Transcript
| 00:00 | wow , we are going to learn so many cool | |
| 00:03 | things on this home school pop video . All right | |
| 00:06 | . What's the first thing we should learn ? How | |
| 00:09 | about addition ? I love Edition . I love it | |
| 00:16 | very much . I love Edition . I add up | |
| 00:19 | all my stuff . I know the voice of an | |
| 00:22 | angel . All right , So , really ? Why | |
| 00:27 | do I love audition ? Why do I love Edition | |
| 00:31 | ? And why should you love Edition ? Well , | |
| 00:35 | I love Edition . Because Edition is so simple and | |
| 00:40 | so much fun . We're gonna show you were gonna | |
| 00:43 | prove to you that addition is so simple and so | |
| 00:46 | much fun . You're gonna have a great time doing | |
| 00:49 | it . Okay , So , you might be wondering | |
| 00:52 | what is addition ? What do we do when we | |
| 00:54 | do addition ? Well , addition is putting numbers together | |
| 00:58 | . It's like a great game of putting numbers together | |
| 01:03 | . Okay , addition is putting numbers together . Now | |
| 01:09 | we're going to show you exactly how this works by | |
| 01:12 | talking about this sport . Do you know what sport | |
| 01:18 | this is ? Okay ? Mhm . Yeah , this | |
| 01:23 | is golf . Mhm . This lady hit the golf | |
| 01:29 | ball and she's hoping that the golf ball goes into | |
| 01:33 | the hole . We're pulling for you sally . Don't | |
| 01:37 | know if you actually got the ball in the hole | |
| 01:39 | but we're pulling for you Sally . You can do | |
| 01:41 | it sally , you can do it . You see | |
| 01:43 | she's so excited . She doesn't know . She doesn't | |
| 01:46 | know . But we don't know either . So anyway | |
| 01:50 | , all we can do is guess we don't really | |
| 01:52 | know sally all that well . But let's pretend that | |
| 01:57 | Sally loves golf and let's pretend that Sally likes to | |
| 02:02 | collect golf balls . So sally is playing with one | |
| 02:09 | golf ball . Let's say that's the only golf ball | |
| 02:13 | she has with her right now she's got one golf | |
| 02:16 | ball but she finds another golf ball by a tree | |
| 02:24 | . So she had one golf ball and then she | |
| 02:27 | found another one . We need to put these numbers | |
| 02:32 | together don't we to find out how many golf balls | |
| 02:35 | she has now putting numbers together . That's that's addition | |
| 02:40 | , that's addition . So now we put these two | |
| 02:45 | numbers together , she had one golf ball , she | |
| 02:49 | found another one . So let's add both of those | |
| 02:53 | balls , how many do we have ? Mhm Yeah | |
| 02:59 | to sally now has two golf balls . Good job | |
| 03:05 | sally , oh audition I knew I loved you audition | |
| 03:11 | . All you are is just putting numbers together . | |
| 03:15 | So simple , so fun a game anyone can play | |
| 03:21 | well you know sally you know sally she went back | |
| 03:26 | to that golf course the very next day because remember | |
| 03:30 | she loves golf right and of course sally brought her | |
| 03:36 | to golf balls because remember she had one golf ball | |
| 03:39 | and she found another one so now she has to | |
| 03:42 | but you know what , she had a great day | |
| 03:44 | at the course and she actually found two more balls | |
| 03:49 | . I know and that crazy sadly is really great | |
| 03:53 | at finding golf balls . She found two more balls | |
| 03:59 | . Now we have to find out how many golf | |
| 04:02 | balls she has . Wait a second . We're putting | |
| 04:06 | that we're putting numbers together . It's addition it's time | |
| 04:09 | we're gonna get to through addition again . Remember addition | |
| 04:12 | is putting numbers together . She had two balls and | |
| 04:16 | now she's found two more balls and we get to | |
| 04:19 | find out how many she has now that's edition putting | |
| 04:23 | numbers together . So she had two balls and she's | |
| 04:29 | found two new ones . So we need to find | |
| 04:31 | out what two plus two is . What a great | |
| 04:36 | addition problem . What's two plus two ? If you | |
| 04:40 | don't know you can actually just count the golf balls | |
| 04:44 | . What's two plus two ? Yeah 42 plus two | |
| 04:51 | equals four . Remember addition is putting numbers together . | |
| 04:59 | Two plus two equals four . That's addition putting numbers | |
| 05:06 | together . Oh bless her heart . Sally's at it | |
| 05:13 | again . She's back at the golf course to collect | |
| 05:18 | more golf balls . So sally brings all of her | |
| 05:23 | golf balls now she has four of them . She | |
| 05:27 | brought all four to the golf course . Well she | |
| 05:32 | looked high and low and wouldn't you know it ? | |
| 05:35 | She found three golf balls during her time at the | |
| 05:39 | golf course . I know she's so good at collecting | |
| 05:42 | golf balls . Now we need to figure out how | |
| 05:47 | many golf balls she has and yes we're putting numbers | |
| 05:50 | together so it's going to be an addition problem . | |
| 05:54 | She had four golf balls and now she has three | |
| 05:59 | more golf balls . So what is four plus three | |
| 06:06 | ? Remember with addition we're just putting numbers together so | |
| 06:12 | if you need help you can actually count the number | |
| 06:15 | of golf balls on the screen . What's four plus | |
| 06:19 | three ? Yeah , four plus three equals seven . | |
| 06:29 | She has seven golf balls now . Great job adding | |
| 06:36 | . Well , now , you know , the basics | |
| 06:39 | of audition and now , you know why I love | |
| 06:42 | auditions so much in the comments below , Tell us | |
| 06:46 | how much you love edition , because it's fun , | |
| 06:49 | right ? It's simple . It's fun . Where sally | |
| 06:52 | , where sally , ah , there she is , | |
| 06:55 | she is , There's our little star . Thanks for | |
| 06:58 | helping us count how many golf balls chicha . And | |
| 07:01 | remember addition is just putting numbers together . We are | |
| 07:07 | so happy to have you with us . I mean | |
| 07:09 | , you are so awesome , You really are . | |
| 07:13 | Oh , you like my poster , Mr Whiskers poster | |
| 07:16 | , You know , it's pretty cool , pretty cool | |
| 07:19 | . You know , it's a pretty cool poster . | |
| 07:22 | Pretty cool cat too . I wonder what he would | |
| 07:24 | like to learn about next . If he would learn | |
| 07:27 | from one of our videos , what would he like | |
| 07:29 | to learn next ? How about , let's learn about | |
| 07:37 | equal parts . We're going to learn how to recognize | |
| 07:41 | if something shows equal parts or if something shows unequal | |
| 07:46 | parts . Hold on . My , my boss is | |
| 07:53 | giving me his pizza order again . I'm telling you | |
| 07:56 | he loves pizza way too much . I mean I | |
| 07:59 | like pizza . It's fine , but he's always giving | |
| 08:03 | me his pizza order . I'm always picking it up | |
| 08:05 | for him and this is just , this is uh | |
| 08:09 | , you know , I just here , I just | |
| 08:11 | got to keep writing down , You know , he's | |
| 08:12 | got all these instructions . He likes his pizza a | |
| 08:15 | certain way . Oh wow . Oh , he's , | |
| 08:20 | he wants , he wants me to have some of | |
| 08:22 | the pizza with him . Oh , man and and | |
| 08:25 | Tad and and Gilbert . Oh , all four of | |
| 08:29 | us having the same pizza . All the sharing of | |
| 08:33 | pizza . So what would that look like ? What | |
| 08:38 | would it look like if we had this pizza put | |
| 08:41 | in four equal parts ? How would we know that | |
| 08:46 | these parts of the pizza were equal mm A pizza | |
| 08:53 | with four equal parts . Might look like this . | |
| 08:56 | Pretty cool . Huh ? We know the parts are | |
| 09:01 | equal because each of the parts are the same size | |
| 09:08 | . Mhm . We're going to play a game called | |
| 09:12 | Are these equal parts ? Okay . It's not really | |
| 09:17 | a game but we can make it into a game | |
| 09:19 | , right , Okay . It's not like checkers , | |
| 09:22 | It's not like chess . You know , it's not | |
| 09:24 | like basketball , like soccer . Okay . It's not | |
| 09:28 | like a game game game . Okay . But it's | |
| 09:31 | still going to be fun and we're gonna be able | |
| 09:34 | to see work with me or Okay , we're gonna | |
| 09:37 | be able to see if these pictures show equal parts | |
| 09:43 | or if these pictures show unequal parts . So here | |
| 09:50 | is our first picture . Now we're gonna be looking | |
| 09:53 | to see if this picture shows equal parts and this | |
| 09:58 | picture shows how many parts . Two good job now | |
| 10:04 | are these equal parts ? Yes this picture shows two | |
| 10:14 | equal parts and we know they're equal because they're the | |
| 10:17 | same size . Now look at this one . This | |
| 10:23 | picture shows how many parts Yeah three parts . Now | |
| 10:30 | are these equal parts ? No they're not equal parts | |
| 10:36 | . They're not equal parts because they're not all the | |
| 10:39 | same size . This picture does not show equal parts | |
| 10:45 | . Great job . Now let's give this picture . | |
| 10:50 | Try how many parts to this picture show three good | |
| 10:57 | job . And are these parts equal parts . No | |
| 11:05 | they're not equal parts . Can you imagine if you | |
| 11:08 | got that bottom part ? If this if this square | |
| 11:11 | was like a cake and you've got that bottom part | |
| 11:14 | . That wouldn't be fair . Why these are not | |
| 11:16 | equal parts . Let's give this triangle picture a try | |
| 11:23 | . How many parts does this picture show ? Great | |
| 11:28 | Job . three . And are these equal parts ? | |
| 11:35 | Yeah . Yes they're equal parts because they are all | |
| 11:39 | the same size . Equal parts means each part is | |
| 11:43 | the same size . Great job . What about this | |
| 11:50 | picture ? How many parts does this picture have ? | |
| 11:54 | Be careful when you count . It's a little bit | |
| 11:57 | tricky . This picture has four parts . Now . | |
| 12:04 | Are these equal parts ? No they're not equal parts | |
| 12:10 | . How do we know because they're not the same | |
| 12:13 | size ? I don't know about you but I feel | |
| 12:20 | pretty good about this . Equal parts stuff . It | |
| 12:23 | just means that the parts are the same size when | |
| 12:26 | they're the same size . That means they're equal oh | |
| 12:31 | this little baby is putting together a little craft you | |
| 12:35 | know it's so great . I just love that . | |
| 12:37 | This has so good . Wait a second . Papers | |
| 12:41 | from that book , isn't it ? Okay , this | |
| 12:44 | is , see this is , this is not an | |
| 12:46 | approved arts and crafts activity right now . Okay , | |
| 12:51 | we're gonna have to take care of this . But | |
| 12:53 | first let's learn about subtraction . Oh , do you | |
| 13:04 | know where I am ? Yeah . You know , | |
| 13:07 | I'm waiting patiently in this waiting room . Oh man | |
| 13:12 | , it has been a while . Have you ever | |
| 13:15 | been in a waiting room before ? Cool . Yeah | |
| 13:23 | , they can be fun but you do have to | |
| 13:24 | be patient and it's a good time to think , | |
| 13:27 | you know , you can think about all kinds of | |
| 13:29 | things like , okay , I have eight cowboy hats | |
| 13:35 | . I know it's crazy . It's weird . Eight | |
| 13:37 | cowboy hats and they're all the exact same . The | |
| 13:41 | exact same hat . I've got eight of them . | |
| 13:44 | Eight brown cowboy hats . I mean what's the guy | |
| 13:49 | going to do with eight brown cowboy hats that look | |
| 13:53 | the exact same ? What could I possibly do with | |
| 13:58 | eight brown cowboy hats that are all the same . | |
| 14:02 | I mean I should probably give some of them away | |
| 14:05 | . You know , I could give away one of | |
| 14:08 | my hats to bob . I'm cooking , might want | |
| 14:11 | one . Yeah , she might like a brown cowboy | |
| 14:13 | hat , you know , I can give one a | |
| 14:16 | nancy , you know just in case she ever got | |
| 14:18 | invited to western party and chomsky , he'd take a | |
| 14:22 | hat . So as I'm sitting here thinking about my | |
| 14:27 | eight hats , I need to figure out how many | |
| 14:29 | hats I'll have left if I give some of them | |
| 14:32 | away to figure that out . We need to use | |
| 14:37 | subtraction . You see subtraction is when you take numbers | |
| 14:42 | away . Yeah , very simple subtraction is when you | |
| 14:45 | take numbers away . So I begin with eight hats | |
| 14:51 | and I decided to give one away . We're gonna | |
| 14:55 | need to subtract one from eight . The way we | |
| 14:59 | would write this is 8 -1 . Now remember when | |
| 15:06 | we subtract we're just taking numbers away so 8 -1 | |
| 15:11 | we're gonna just take one away . There we go | |
| 15:15 | . How many hats do I have left ? What | |
| 15:18 | is 8 -1 ? If it helps you can just | |
| 15:22 | count how many hats I have left . What is | |
| 15:26 | 8 -1 ? Mm . Yeah seven eight minus one | |
| 15:34 | is seven . Now I have seven hats . Remember | |
| 15:41 | subtraction is when you take numbers away and as you | |
| 15:46 | might have noticed we use the minus sign when we | |
| 15:49 | write a subtraction problem you can see it right there | |
| 15:53 | in the middle . It's just like a dash that's | |
| 15:56 | the minus sign . So now I have seven hats | |
| 16:01 | but two of my friends stopped by and I decided | |
| 16:03 | you know what I know I just have seven hats | |
| 16:06 | now but I want to give two of them away | |
| 16:09 | . Now I'm gonna be subtracting two hats from my | |
| 16:13 | collection . We would write this by saying 7 -2 | |
| 16:21 | . Now let's take away two hats . We'll find | |
| 16:23 | out how many we have left . What a wonderful | |
| 16:26 | subtraction problem . What is 7 -2 . If you | |
| 16:32 | need help you can just count how many hats are | |
| 16:34 | left . What is 7 -2 ? Seven minus two | |
| 16:40 | equals five . Yeah . Five hats . And you | |
| 16:44 | can even count them 12345 There are five hats left | |
| 16:49 | . Seven minus two equals five . Do you see | |
| 16:55 | how fun and simple subtraction is ? Subtraction is when | |
| 16:59 | you take numbers away . So now I have five | |
| 17:04 | hats in my collection . Only five hats left . | |
| 17:08 | But then I meet up with my cousins who we | |
| 17:11 | dewey and Stewie who want to have hats too and | |
| 17:15 | I'd love to give them hats so I'm gonna give | |
| 17:18 | three more hats away . So I have five hats | |
| 17:22 | and we're gonna subtract three hats , we would write | |
| 17:25 | that five minus three . Oh I love subtraction so | |
| 17:33 | much . Alright Bada Bing . There we go . | |
| 17:38 | The three hats are gone , so 5 -3 . | |
| 17:43 | How many hats are left ? It's pretty simple , | |
| 17:47 | isn't it ? Mhm , mm hmm . Yeah 5 | |
| 17:54 | -3 equals two . Good job . Subtraction is just | |
| 17:59 | taking numbers away and 5 -3 leaves you with two | |
| 18:04 | . Now I have just two hats . We love | |
| 18:08 | subtraction . I mean subtraction is when you take numbers | |
| 18:13 | away and why am I in the middle of the | |
| 18:16 | road with the shopping card ? So I had my | |
| 18:23 | two hats and that's fun because then the hat has | |
| 18:27 | a friend and they're like buddies and they're like a | |
| 18:30 | pair of friends and then chomsky came by and I | |
| 18:38 | said oh I'm going to have to do subtraction again | |
| 18:43 | , I'm going to have to subtract again . Old | |
| 18:45 | chomsky , you know the charms the game by , | |
| 18:50 | I said I'm going to have to subtract again Mhm | |
| 18:55 | I'm going to have to subtract one more time , | |
| 19:01 | so I have two hats minus one , 2 -1 | |
| 19:09 | . So we subtract that one , we take that | |
| 19:13 | one away and how many hats are left ? What | |
| 19:17 | is 2 -1 , yep , 2 -1 equals one | |
| 19:28 | . There's only one hat left , which is fine | |
| 19:31 | . I mean you know , I can only wear | |
| 19:33 | one hat at a time and it was the same | |
| 19:36 | exact hat I think about it . Subtraction has been | |
| 19:40 | good to me , it's good . Subtraction is taking | |
| 19:43 | numbers away Sometimes . I do wonder what would have | |
| 19:50 | happened if I didn't give that Hattaway . If if | |
| 19:55 | hat he still had his friend they could have gone | |
| 19:58 | to the beach together . They could have gone to | |
| 20:01 | birthday parties together . But actually they had a better | |
| 20:08 | purpose to make a friend happy . So in this | |
| 20:13 | waiting room , all I got to say is thanks | |
| 20:17 | subtraction . You are pretty awesome . Oh this is | |
| 20:29 | such a heavy cart . Oh my goodness . It's | |
| 20:33 | hard work . You know A lot of times learning | |
| 20:35 | can be hard work too . But we hope that | |
| 20:38 | these videos are really helpful . Make learning fun . | |
| 20:41 | So that learning is hard like pushing this cart . | |
| 20:45 | Oh my goodness ! All right . What's the next | |
| 20:48 | thing we should learn about ? Let's learn about even | |
| 20:53 | and odd numbers . A number belongs to one of | |
| 20:57 | two groups . Either it's an even number or it's | |
| 21:00 | an odd number . So what's going on ? Why | |
| 21:03 | is this even a thing we're going to talk about | |
| 21:06 | it even in odd is actually pretty easy , but | |
| 21:12 | it's just a matter of knowing what to look for | |
| 21:15 | . So we're going to be like detectives together . | |
| 21:17 | Okay , You're gonna have to have an eagle , | |
| 21:20 | uh , to help us out on her quest . | |
| 21:23 | We're gonna use dinosaurs , dinosaurs are awesome . And | |
| 21:27 | here's a red dinosaur . That's I don't know why | |
| 21:30 | it's windy . There's wind going on . And I | |
| 21:33 | don't know what's what's let's change the scenery . Let's | |
| 21:36 | let's make it more modern day . There you go | |
| 21:39 | . Look at that . Just walking through the neighborhood | |
| 21:41 | strolling . He's ready to help us discover the secret | |
| 21:48 | , right to knowing even an odd . So what | |
| 21:52 | is this key that we're looking for ? What are | |
| 21:54 | we looking for that will tell us if a number | |
| 21:56 | is even or if the number is odd and even | |
| 22:02 | number can be grouped by to an odd number cannot | |
| 22:07 | be evenly grouped by two . So it's all about | |
| 22:10 | the number two . And that might sound confusing . | |
| 22:12 | Let me show you and you'll see here is the | |
| 22:16 | easiest number to do . We're looking for the number | |
| 22:20 | two . Okay . Can it be put in a | |
| 22:23 | group of two ? Well yes because it's the number | |
| 22:25 | two . We've got to dinosaurs . That makes to | |
| 22:28 | even now this is odd . This dinosaurs All alone | |
| 22:34 | . He's not in a group of two . This | |
| 22:36 | makes the number one an odd number because he's all | |
| 22:40 | alone . That's odd . It's an odd number . | |
| 22:45 | Let's look back at the number to see what's neat | |
| 22:48 | about . This is it's an even group of two | |
| 22:51 | . That means our dinosaur has a friend , he | |
| 22:53 | can talk to his friend , he can hang out | |
| 22:55 | . It's not it's not weird . It's not odd | |
| 22:58 | . It's an even number here . We have three | |
| 23:01 | dinosaurs . Now can we put the number three in | |
| 23:05 | even groups of two ? Well no because that third | |
| 23:08 | dinosaurs all alone . The top two dinosaurs have somebody | |
| 23:11 | three is odd . There's one that's missing a partner | |
| 23:15 | here we have four dinosaurs . Now we're looking for | |
| 23:19 | groups of the number two . Now we have two | |
| 23:22 | groups of . To hear . That means it's an | |
| 23:24 | even number . Each dinosaur has a friend , wow | |
| 23:31 | five dinosaurs but look One on the bottom doesn't have | |
| 23:36 | a pal , doesn't have a friend . That's odd | |
| 23:40 | . It's not evenly grouped into 25 is an odd | |
| 23:44 | number . Hey buddy . Okay . Don't don't run | |
| 23:47 | . Okay , we'll get back to the even numbers | |
| 23:49 | . I know you don't like the odds . You | |
| 23:50 | don't like being the odd dinosaur out . It's okay | |
| 23:53 | . I promise this next number is going to be | |
| 23:56 | even because it goes for even odd , even odd | |
| 23:59 | . Just hang on man dinosaurs . You know , | |
| 24:04 | so temperamental . You know I mean what's that all | |
| 24:08 | about ? I mean a dog , dog wouldn't have | |
| 24:10 | done that . You know , dogs are better I | |
| 24:13 | think now than dinosaurs . You know , I'm just | |
| 24:18 | kidding , dinosaurs are so cool . Moving on here | |
| 24:27 | we have six dinosaurs now . Each dinosaur has a | |
| 24:32 | friend . That means six is even . You can | |
| 24:36 | split it up in groups of two . Oh here | |
| 24:42 | we have seven dinosaurs . But there's one dinosaur that's | |
| 24:46 | all alone . Six of them have friends . But | |
| 24:49 | one is all alone . Doesn't have a pair . | |
| 24:51 | Seven is odd for the number eight . Does everyone | |
| 24:59 | have a friend ? Yes , there's no one without | |
| 25:02 | a friend . Number eight is an even number . | |
| 25:06 | It splits up into two very nicely . Eight is | |
| 25:09 | even let's go even higher than number nine . Now | |
| 25:14 | you can see really quick , it's easy to spot | |
| 25:17 | is nine even or odd . Yes , it's odd | |
| 25:22 | . There's one who doesn't have a friend . Nine | |
| 25:24 | Izod . Oh my goodness . 10 . 10 is | |
| 25:29 | it even or is odd ? You tell me you | |
| 25:33 | know how to do it now . You know the | |
| 25:34 | trick ? Yes , 10 is even everybody has a | |
| 25:39 | friend . Now we're about to teach you to sneaky | |
| 25:45 | tricks that you can use with even and odd numbers | |
| 25:49 | . Okay , so seriously ? Because it's well it's | |
| 25:53 | it's not it's not really sneaky . But anyway , | |
| 25:57 | so this first trick is that all of the numbers | |
| 26:00 | alternate from odd to even and back . And we're | |
| 26:05 | going to show you what that means and what that | |
| 26:08 | looks like . Here we have the 1st 10 numbers | |
| 26:14 | , numbers one through 10 . And the trick was | |
| 26:17 | all of the numbers alternate from odd to even and | |
| 26:21 | back . Do you remember if number one is odd | |
| 26:24 | or even ? Yeah . Yes . Number one is | |
| 26:30 | odd because remember number one all by himself doesn't have | |
| 26:33 | a friend , doesn't have a partner . It's not | |
| 26:35 | an even number . Number one is odd . Now | |
| 26:39 | we remember number two right . Number two is even | |
| 26:44 | . Yes because it can be grouped into because it | |
| 26:46 | is too . Now if they alternate that means which | |
| 26:50 | one is number three it's odd . This is where | |
| 26:58 | it gets fun . If three is odd then that | |
| 27:01 | means four is yeah even good job . And if | |
| 27:08 | four is even , that means five must be odd | |
| 27:14 | . Yeah and if five is odd , that means | |
| 27:18 | six must be you guessed it even and if six | |
| 27:24 | is even , that means seven must be odd . | |
| 27:30 | Yes seven is odd . If seven is odd that | |
| 27:34 | means eight is come on . What's the pattern ? | |
| 27:37 | Eight is even and if aid is even , that | |
| 27:41 | means night must be odd and nine is odd . | |
| 27:46 | Come on . Is this not just the most fun | |
| 27:48 | drink ever ? If nine is odd , that means | |
| 27:53 | 10 is even . They all alternate . So the | |
| 27:58 | first trick is that they alternate , the numbers alternate | |
| 28:02 | , odd , even odd , even odd , even | |
| 28:06 | odd , even odd . Even now . We're going | |
| 28:09 | to look at the second trick . The second trick | |
| 28:12 | is that with numbers bigger than 10 If it's odd | |
| 28:16 | or even you can see on the end With numbers | |
| 28:21 | bigger than 10 . If it's odd or even you | |
| 28:23 | can see on the end to demonstrate , let's play | |
| 28:30 | a game . We here at home school pop call | |
| 28:33 | Odd or even . We're gonna look at a number | |
| 28:37 | that's bigger than 10 . We're gonna look on the | |
| 28:39 | end to see if it's even or if it's odd | |
| 28:43 | . Our 1st 1 is the number 21 . Is | |
| 28:46 | it odd ? Or is it even ? It's odd | |
| 28:52 | . How why what we look on the end ? | |
| 28:55 | The end is a one . A one is odd | |
| 28:58 | . It's all by itself . A one is odd | |
| 29:02 | . So 21 is odd because one is the ending | |
| 29:06 | . It did . You know ? That means 71 | |
| 29:12 | is odd and 101 is odd and 131 is odd | |
| 29:18 | and the number 1000 and one is odd . Why | |
| 29:21 | they all end in ? What ? Let's try this | |
| 29:25 | one . The number 32 . Is it odd ? | |
| 29:28 | Or is it even 32 is even ? Well how | |
| 29:36 | do we know because of the ending ? Look at | |
| 29:38 | the ending , it's the number 22 is an even | |
| 29:41 | number because it's a group of two . It can | |
| 29:44 | be put in groups of two because it is to | |
| 29:47 | the same rule applies . This is the second trick | |
| 29:50 | with numbers bigger than 10 if it's odd or even | |
| 29:53 | you can see on the end every single number that | |
| 29:58 | you can think of ends in two is an even | |
| 30:02 | number . Let's try one . That's a little more | |
| 30:09 | tricky . Let's try the number . 100 is 100 | |
| 30:13 | odd or is it even 100 is even ? It's | |
| 30:26 | even and we know that because of the ending , | |
| 30:29 | it ends in a zero . Now remember second trick | |
| 30:33 | with numbers bigger than 10 if it's odd or even | |
| 30:37 | You can see on the end and ending is a | |
| 30:40 | zero and every number that ends and zero is even | |
| 30:45 | . Let's look at the chart again As you can | |
| 30:49 | see 10 on the bottom ends in zero . And | |
| 30:54 | it's even every single number that ends in zero is | |
| 30:58 | even just like every number that ends in a one | |
| 31:01 | is odd . Every number that ends in a two | |
| 31:04 | is even . Every number that ends in a three | |
| 31:08 | is odd because three is odd . Every number that | |
| 31:11 | ends in a four is even and it goes on | |
| 31:14 | and on , numbers that end in five are odd | |
| 31:17 | , numbers that end in six or even numbers that | |
| 31:20 | end in seven are odd . Yeah , Numbers that | |
| 31:26 | end in eight are even numbers that end in nine | |
| 31:31 | are odd and the numbers like 10 end in zero | |
| 31:35 | are always even . So there you go odd . | |
| 31:40 | And even as long as you learn these , you'll | |
| 31:44 | know any number because the endings always tell you if | |
| 31:48 | it's otter even . So once you know these , | |
| 31:50 | you'll know all of them , You're doing great . | |
| 31:56 | You're increasing your skills just like this razor , you're | |
| 31:59 | racing on the water , you're increasing your skills , | |
| 32:02 | you're doing a wonderful job . And next we are | |
| 32:06 | going to learn about three dimensional shapes . This is | |
| 32:11 | gonna be awesome . Love the three D shapes . | |
| 32:13 | A lot of people know the two D shapes . | |
| 32:15 | You might not know the three D shapes . You're | |
| 32:17 | in the right place before we get started . Me | |
| 32:21 | just dance here real quick . This is really cool | |
| 32:24 | music . I really like this . You know , | |
| 32:25 | I like the dance . You know , some people | |
| 32:27 | , they're not dancers , you know , I dance | |
| 32:29 | , I dabble and dancing , you know ? All | |
| 32:33 | right , that's enough . Can somebody turn that music | |
| 32:36 | off ? Seriously ? I can I can't teach like | |
| 32:38 | this . I can't teach with this music going on | |
| 32:41 | . You know , I didn't feel like I'm in | |
| 32:42 | a candy shop . Listen to some music off , | |
| 32:44 | please . Thanks . So here they are , our | |
| 32:49 | old friends . The two D shapes . You're familiar | |
| 32:52 | with these . You know , you're familiar with the | |
| 32:54 | circle , the oval , the triangle , the pentagon | |
| 32:59 | , the trapezoid , the hex a gone , the | |
| 33:02 | square , the rectangle , the parallelogram in the octagon | |
| 33:07 | . These are all our our shapes , R2D shapes | |
| 33:11 | , you know , but these are old family friends | |
| 33:13 | of ours . We don't want to just Forget about | |
| 33:16 | these . And before we look at 3D shapes , | |
| 33:18 | it's really important for us to look at these shapes | |
| 33:21 | again because these are old friends . So we're gonna | |
| 33:24 | look at each one of these one by one just | |
| 33:26 | to make sure you know who they are . Before | |
| 33:29 | we learn all these new shapes . This first shape | |
| 33:34 | doesn't even need an introduction . It's the circle , | |
| 33:37 | the circle that round figure . It's awesome . We | |
| 33:40 | love this shape . It's one of the first ones | |
| 33:43 | we ever learn the circle . This next shape is | |
| 33:48 | one of the stretchy shapes . The oval , it's | |
| 33:51 | like a circle got stretched out . Its elongated . | |
| 33:55 | It's a tremendous shape . The oval , mm . | |
| 34:02 | Mhm . Here's another familiar shape . The triangle . | |
| 34:06 | Three sides . We love the triangle . The triangle | |
| 34:11 | is great , The three sighted friend . Three sides | |
| 34:14 | . A triangle . Wait , I keep saying we | |
| 34:19 | love the shapes . I mean we like the shapes | |
| 34:22 | . But do you love the shapes ? Do I | |
| 34:24 | love the shapes ? I mean , I don't know | |
| 34:27 | . I need to take it easy here . Uh | |
| 34:30 | All right , let's keep going . Yeah . Ah | |
| 34:34 | The square of four sides all equal . You know | |
| 34:38 | , the square is good . The squares a good | |
| 34:40 | shape . You know , sometimes you just need a | |
| 34:43 | square . Sometimes you just need a square . Here's | |
| 34:49 | the rectangle . The rectangle is longer than the square | |
| 34:54 | because not all four sides are equal . The rectangle | |
| 35:00 | . I know I'm we're in the middle of something | |
| 35:04 | here , but I have to share this . Okay | |
| 35:05 | , so what do you call a hamster with a | |
| 35:08 | top hat ? Abraham stir Lincoln . I digress the | |
| 35:18 | trapezoid . A cool shape with two of the sides | |
| 35:22 | being parallel to each other and the parallelogram , another | |
| 35:25 | four sided shape . Both pairs of sides are parallel | |
| 35:30 | to each other and finally the pentagon with five sides | |
| 35:36 | . The hex a gone with six sides and the | |
| 35:38 | octagon with eight sides . What awesome shapes . So | |
| 35:48 | let's go ahead and do a quick to D shaped | |
| 35:51 | quiz . I need your help . I want to | |
| 35:53 | see if you really learn these if you really know | |
| 35:56 | these before we get into the three D . Shape | |
| 35:57 | . So help me out here , we're gonna have | |
| 35:59 | an awesome time . Wait what ? It's not my | |
| 36:05 | birthday . Oh well what type of shape is on | |
| 36:09 | the top ? Yeah . Yeah . A circle . | |
| 36:16 | What type of shape is in the middle ? A | |
| 36:23 | square , awesome . Okay now what shape is on | |
| 36:29 | the bottom ? Of course A triangle , awesome job | |
| 36:36 | . Now we've got more , this is a little | |
| 36:40 | trickier . Which shape is in the middle ? Mhm | |
| 36:44 | mm . Yeah . A trapezoid . Which shape is | |
| 36:50 | on the right ? The pentagon . Good job . | |
| 36:57 | And which shape is on the left ? Yeah , | |
| 37:05 | the square . Now try these . Which shape is | |
| 37:12 | on the bottom ? Yeah , the oval . Which | |
| 37:19 | shape is on the top ? Yeah , the parallelogram | |
| 37:28 | . Which shape is in the middle . All right | |
| 37:35 | . The rectangle . Great job . All right . | |
| 37:39 | The last one which shape is on the left ? | |
| 37:48 | Yeah , the hexagon which shape is on the right | |
| 37:58 | . Great . The octagon and which shape is in | |
| 38:02 | the middle , phenomenal ? The pentagon . Yeah . | |
| 38:10 | All right . We're ready to learn the three D | |
| 38:13 | shapes . We're going to learn how to identify the | |
| 38:16 | three dimensional shapes . If you struggle through the quiz | |
| 38:19 | , you might want to watch the first part of | |
| 38:21 | the video again . Otherwise let's get started . So | |
| 38:26 | as we're starting out it's important to remember what makes | |
| 38:30 | a three D . Shape a three D . Shape | |
| 38:33 | . There's an old rhyme that says three D shapes | |
| 38:36 | are fat , not flat . And you can see | |
| 38:38 | that with the sphere which is a three D . | |
| 38:41 | Shape . We're about to learn and the circle , | |
| 38:44 | the circle is flat but the sphere is three D | |
| 38:49 | . It's three Dimensional . All the shapes are like | |
| 38:52 | that . So let's learn all these three D shapes | |
| 38:56 | . So the first three D . Shape we're going | |
| 38:58 | to learn is the sphere , the one that we | |
| 39:01 | just mentioned . The sphere is the three D . | |
| 39:03 | Version of the circle . It's perfectly round . There | |
| 39:12 | are spheres all around us . One of the spheres | |
| 39:14 | we see all the time . Our balls like this | |
| 39:17 | soccer ball , a soccer ball is a sphere , | |
| 39:21 | it's perfectly round , it's a three D circle . | |
| 39:23 | It's a sphere , you know this fear , Yes | |
| 39:27 | , it's the Earth , it's where we live . | |
| 39:30 | Our planet is a sphere . How cool is that | |
| 39:34 | ? Our own planet is a sphere perfectly round . | |
| 39:38 | It's a sphere in this picture . We have two | |
| 39:43 | spheres . Can you spot them ? Yeah , the | |
| 39:46 | two spheres are the two bullying balls . Perfect round | |
| 39:52 | spheres , spheres are all around us . Here we | |
| 39:57 | have a group of three spheres and you can count | |
| 40:00 | them right now . 123 spheres all together the shape | |
| 40:06 | of a ball , a sphere perfectly round . Well | |
| 40:12 | there you have it . The sphere . What a | |
| 40:14 | cool three D shape to start with . Its round | |
| 40:17 | there examples all around us and it's just so cool | |
| 40:21 | . And you know what ? The three d shapes | |
| 40:23 | are going to get even better . Our second three | |
| 40:28 | D shape is the cone . The cone is a | |
| 40:31 | really cool shape with a circle as the base or | |
| 40:35 | the bottom . And it all comes up to one | |
| 40:38 | point called a vertex . Here's an example of a | |
| 40:42 | cone . I think we all love the ice cream | |
| 40:45 | cone . If it doesn't have any ice cream inside | |
| 40:47 | and you flipped it upside down , you'd be able | |
| 40:49 | to see the circle base and it all comes up | |
| 40:52 | to one point called the vertex . Here are two | |
| 40:57 | cones , a red cone and a blue cone . | |
| 41:01 | And you can see both cones have that circle basin | |
| 41:04 | . All comes up to of vertex . What ? | |
| 41:07 | Wonderful cones ? Yeah . Have you seen these before | |
| 41:12 | ? Their traffic cones here are many cones . I | |
| 41:17 | didn't count all of them , but there's a lot | |
| 41:20 | and they're wonderful wonderful cones . Yeah . So that's | |
| 41:25 | our second three D shape . The kona wonderful cone | |
| 41:29 | with the great circle base . It all comes up | |
| 41:32 | to one point called the vertex . How awesome is | |
| 41:37 | that ? Our third three D shape is the pyramid | |
| 41:41 | . I love the pyramid . The pyramid is great | |
| 41:43 | . It comes up to one point just like the | |
| 41:46 | cone . Except the base is a square and the | |
| 41:48 | sides instead of being smooth . They are triangles . | |
| 41:54 | Okay like these are awesome . These are so cool | |
| 41:59 | . The pyramids of Egypt , you see that they | |
| 42:01 | have the triangle sides and the bottoms of these pyramids | |
| 42:06 | are square . They're awesome examples of the pyramid . | |
| 42:09 | This is a pretty cool pyramid . It's a decoration | |
| 42:12 | that you plug into the wall but it's a great | |
| 42:14 | example of what a pyramid looks like . The bottom | |
| 42:17 | of the bases square . And there's the triangles on | |
| 42:21 | the sides . How cool is this ? Here's another | |
| 42:26 | pyramid and it's made of glass . There are so | |
| 42:29 | many decorations and things around . Maybe even your house | |
| 42:33 | that are shaped like a pyramid because pyramids look so | |
| 42:36 | cool . People love putting them everywhere . There you | |
| 42:40 | go . I mean , you know the pyramid ? | |
| 42:41 | It's in good shape . You know , you see | |
| 42:42 | a lot of them around . They've got the square | |
| 42:45 | bottom or base and the triangles on the sides and | |
| 42:49 | all goes up to a vertex . It's a classic | |
| 42:51 | shape . It's pretty awesome . Our 4th 3D shape | |
| 42:57 | is the cylinder . Now a cylinder is easy to | |
| 42:59 | spot because it's got a circle on the top and | |
| 43:02 | a circle on the bottom . And it's smooth all | |
| 43:06 | around here we have a can of soup and it's | |
| 43:12 | a cylinder has a circle on the top , a | |
| 43:15 | circle on the bottom and it's smooth all around . | |
| 43:19 | All cans and most jars are cylinders . Here we | |
| 43:24 | have three cylinders . Their candles . And can I | |
| 43:27 | tell you a secret ? Most candles are cylinders to | |
| 43:32 | write this . This is just too crazy and too | |
| 43:37 | awesome . Here are two more cylinders . Are you | |
| 43:41 | kidding me ? Are you kidding me ? Even batteries | |
| 43:44 | are cylinders , cylinders are seriously everywhere . A circle | |
| 43:48 | on the top , a circle on the bottom and | |
| 43:51 | smooth all around . I mean really ? The cylinder | |
| 43:55 | is everywhere . I mean , you know the circle | |
| 43:58 | on the top circle on the bottom , smooth all | |
| 44:00 | around . I cylinder like what in the world do | |
| 44:03 | you have to be everywhere ? Okay , the next | |
| 44:10 | three D shape is the cube . The cube is | |
| 44:13 | the three D version of the square . It has | |
| 44:16 | six sides or faces that are all squares . Mm | |
| 44:22 | hmm . Here we have two dice dice are in | |
| 44:27 | the shape of a cube . So these two dice | |
| 44:30 | or two cubes , they have six sides or faces | |
| 44:34 | that are all squares . Here we have many cubes | |
| 44:41 | . These are cubes that are made out of wood | |
| 44:44 | . Each of them have six sides or faces that | |
| 44:48 | are all squares . Here are seven cubes of ice | |
| 44:56 | . Have you ever had a warm drink and you | |
| 44:58 | need to put ice in it ? It's awesome because | |
| 45:00 | it has this great shape , the shape of a | |
| 45:03 | cube , six sides or faces all squares . I | |
| 45:08 | mean there you go . The cube , right ? | |
| 45:11 | The three D version of a square . And it's | |
| 45:14 | got squares all along The sides , right there . | |
| 45:18 | six sides or faces all squares . And I don't | |
| 45:21 | know . I think it's pretty cool shape . Mm | |
| 45:26 | Our final three D shape is the rectangular prism . | |
| 45:29 | The rectangular prism is the three D version of the | |
| 45:32 | rectangle . It has six sides or faces that are | |
| 45:36 | all wrecked . Okay . An awesome example of the | |
| 45:40 | rectangular prism are bricks and here we have four bricks | |
| 45:44 | which are four rectangular prisms . The three D . | |
| 45:48 | version of the Rectangle . You may have seen this | |
| 45:55 | in your classroom or in your home . It's a | |
| 45:58 | clean Xbox . And the clean Xbox is a great | |
| 46:01 | example of the rectangular prism . It's got six sides | |
| 46:05 | or faces that are all rectangles . Okay , so | |
| 46:08 | the secret is , most boxes are rectangular prism . | |
| 46:13 | So here's another rectangular prism and it's a box and | |
| 46:16 | it's a shorter box , but it still has rectangles | |
| 46:19 | all around . And it's rectangular prism . What else | |
| 46:25 | can we say ? It's a cool shape . The | |
| 46:27 | rectangular prism is the three D . Version of the | |
| 46:30 | rectangle has six sides or faces that are all rectangles | |
| 46:34 | . And it's just a neat shape to have around | |
| 46:37 | , I think . I mean , you know . | |
| 46:39 | Okay , so let's review . Pyramid , mm hmm | |
| 47:04 | cylinders , mhm sphere , mhm cylinder cones . Yeah | |
| 47:33 | . Pyramid , rectangular prism . Mhm . Mhm spheres | |
| 47:50 | . Let's do some more On the top here . | |
| 47:56 | We have cubes . We can tell that because it's | |
| 48:00 | the 3D square . It has six sides or faces | |
| 48:04 | . Each of them are squares . Is pretty cool | |
| 48:07 | . Do you remember what shape these bricks are ? | |
| 48:10 | Yeah , a rectangular prism . They are rectangular prisms | |
| 48:16 | there . The 3D versions of the rectangle at the | |
| 48:24 | top . We have a cone cone . It's got | |
| 48:29 | a circle base on the bottom and all comes up | |
| 48:33 | to one point called a vertex . Do you remember | |
| 48:37 | the shape here on the bottom ? These are three | |
| 48:41 | cylinders . They have a circle on the top and | |
| 48:45 | a circle on the bottom . And it's smooth all | |
| 48:49 | around . You're doing such an awesome job . Seriously | |
| 48:56 | . So , cool . So , what's this top | |
| 48:58 | shape , do you remember ? Yeah , it's a | |
| 49:01 | pyramid . A pyramid . A pyramid has a square | |
| 49:04 | base . It comes up to one vertex or one | |
| 49:07 | point and has triangles as the sides . All right | |
| 49:16 | . Do you remember this last shape here on the | |
| 49:18 | bottom ? Yes . It's the sphere , the sphere | |
| 49:22 | which is the three D . Circle . And we | |
| 49:25 | started with it and we're ending with it and it's | |
| 49:27 | so awesome . Hey Petey . I know , I | |
| 49:34 | know I heard about your plane . You know it's | |
| 49:36 | a cool plane . You know and and it's it's | |
| 49:39 | neat . I don't know if it flies or you | |
| 49:41 | you look pretty confident that it's gonna fly which is | |
| 49:44 | cool . Yeah , I see you . Hello ? | |
| 49:48 | Yeah thanks for waving . Thanks for saying hello . | |
| 49:50 | You know we're actually in the middle of learning , | |
| 49:52 | we're in the middle of learning a lot of new | |
| 49:55 | cool things right now . So I actually do have | |
| 49:58 | to go high . You're still waving . Okay . | |
| 50:00 | Um We're gonna go because now we need to learn | |
| 50:05 | about roman numerals , which is a different way to | |
| 50:09 | write numbers . And it was used a long time | |
| 50:12 | ago in ancient Rome . And it's been used since | |
| 50:15 | then . And you can think of it almost as | |
| 50:17 | a secret code way of writing the numbers . It's | |
| 50:21 | pretty simple to learn . And we're going to go | |
| 50:23 | through that . The first roman numeral we're going to | |
| 50:28 | learn is the roman numeral . I and I is | |
| 50:33 | one I equals one . So if you see an | |
| 50:37 | eye with the roman numeral , it's one . The | |
| 50:40 | letter V . Is the roman numeral that means five | |
| 50:45 | . And the letter X . Is the roman numeral | |
| 50:49 | that means 10 . So when you think one it's | |
| 50:53 | an eye , you think five , it's a V | |
| 50:57 | . And if you think 10 it's an X . | |
| 51:02 | So that's it . Just those three . I it | |
| 51:06 | almost looks like a one . That's how you can | |
| 51:08 | remember that . I is a one I . Is | |
| 51:12 | the roman numeral for one . A V . Is | |
| 51:15 | in the number five . When you spell it out | |
| 51:17 | the number five , you see that right there . | |
| 51:19 | It has a V . In it . So when | |
| 51:21 | you think of V . You know oh you know | |
| 51:24 | what ? There's a V . In the spelled out | |
| 51:28 | number five . So the has to be five now | |
| 51:32 | 10 is exit , we can't think of anything that | |
| 51:36 | could remind us of that . So there is no | |
| 51:38 | memorization thing just when you see the exits 10 and | |
| 51:42 | that's just what we're going to have to do . | |
| 51:45 | Mhm . Okay , one last time here , I | |
| 51:47 | just want to make sure you get it . There's | |
| 51:49 | only three . I is the roman numeral for one | |
| 51:52 | , the is the roman numeral for five and X | |
| 51:57 | . Is the roman numeral for 10 . And you've | |
| 52:00 | got to understand that so that we can start playing | |
| 52:02 | kind of a game of putting them together And making | |
| 52:06 | numbers other than just 15 and 10 . So let's | |
| 52:10 | get started . So let's practice putting these Roman numerals | |
| 52:17 | together . What number do you think this is two | |
| 52:22 | ? U . C . Two eyes and i is | |
| 52:26 | one . So the answer is to two eyes is | |
| 52:32 | the number 21 What about this one ? You what | |
| 52:41 | number do you think this is why there are three | |
| 52:46 | eyes ? Yeah it's the number three . The let's | |
| 52:54 | try this one . What number do you think this | |
| 52:57 | is ? We see two X . Is an X | |
| 53:04 | equals 10 . So 10 plus 10 equals 20 . | |
| 53:10 | Great job . This is the number 20 . Whoa | |
| 53:19 | . This one is so cool . Okay . An | |
| 53:22 | X . And A V . What number do you | |
| 53:24 | think ? This is A A . The X . | |
| 53:30 | Is a 10 V . Is what number five , | |
| 53:36 | awesome . So what is 10 plus five ? 15 | |
| 53:44 | . Whoa . Thanks so much for helping out now | |
| 53:49 | that we've looked at how to put some of these | |
| 53:51 | together . I want to tell you about two special | |
| 53:54 | numerals that are a little bit different . And so | |
| 53:57 | you're gonna have to just remember these on their own | |
| 54:00 | . The first is the number four and the number | |
| 54:02 | four is represented with an I . And V . | |
| 54:06 | And eyes before the V . Because four is one | |
| 54:10 | less than five which is V . So remember with | |
| 54:14 | four its I . V . With nine similar except | |
| 54:20 | with the X . Nine is I . X . | |
| 54:23 | X . Is 10 and I is just before it | |
| 54:26 | . So nine is I . X . Okay . | |
| 54:31 | That was really cool . Thanks for hanging out and | |
| 54:34 | learning those with me . But we're not done . | |
| 54:36 | We want to go through all the numbers up to | |
| 54:39 | 30 just using the numerals and I want to see | |
| 54:42 | how much you've really learned . So if you'll do | |
| 54:45 | me a favor as the numerals go up , I | |
| 54:48 | want you to say the numbers along with me and | |
| 54:52 | we can practice together . Sound good . Alright , | |
| 54:55 | let's get started . One two 34 five , sex | |
| 55:12 | seven eight nine 10 11 . Mhm . 12 13 | |
| 55:27 | , 14 15 , 16 , 17 , 18 , | |
| 55:38 | 19 , 20 21 22 23 24 25 26 , | |
| 55:52 | 27 28 29 and 30 . Mhm . Well there | |
| 56:00 | you have a new way to write numbers , wow | |
| 56:05 | . You completed the video . That is so impressive | |
| 56:09 | . Well , you might notice there's a circle right | |
| 56:11 | here on this video page that you can click to | |
