| 00:0-1 | in this video , we are going to teach you | |
| 00:03 | a really cool trick . No , it has nothing | |
| 00:05 | to do with yo yo's , although you can learn | |
| 00:09 | a lot of tricks with the yo yo . So | |
| 00:11 | what is this number trick ? It's something cool called | |
| 00:15 | Rounding numbers . Rounding numbers . Mhm . Let's say | |
| 00:21 | Frankie Loves playing tennis , he loves playing tennis so | |
| 00:25 | much , he has a huge collection of tennis balls | |
| 00:30 | . In fact , Frankie owns 39 tennis balls . | |
| 00:34 | His friends know he collects tennis balls . So one | |
| 00:37 | of his friends asked him about how many tennis balls | |
| 00:41 | do you have ? His friend isn't asking for the | |
| 00:46 | exact amount his friend is asking about how many tennis | |
| 00:49 | balls do you have ? His friend could have also | |
| 00:53 | asked this way , roughly how many tennis balls do | |
| 00:57 | you have , Frankie knows that 39 is just one | |
| 01:02 | less than 40 as you can see from this number | |
| 01:05 | line . So he answers , I have about 40 | |
| 01:08 | tennis balls that's rounding . Rounding . Makes a number | |
| 01:13 | more simple when knowing the exact number isn't important . | |
| 01:18 | That's pretty awesome . Rounding makes a number more simple | |
| 01:21 | when knowing the exact number isn't important . In our | |
| 01:27 | example , Frankie rounded the number 39 up to the | |
| 01:30 | number 40 . His friend didn't want to know the | |
| 01:33 | exact number of tennis balls . His friend asked for | |
| 01:38 | an estimate Frankie has about 40 tennis balls . Rounding | |
| 01:44 | is especially common with bigger numbers . For example , | |
| 01:48 | did you know about six million people visit the famous | |
| 01:51 | coliseum in Rome each year ? Do exactly six million | |
| 01:56 | people visit the coliseum each year ? No , that's | |
| 01:59 | why we said about six million the exact number was | |
| 02:03 | rounded so that the number we shared would be simple | |
| 02:07 | and easy to remember . That's what Rounding does . | |
| 02:12 | Rounding makes a number more simple when knowing the exact | |
| 02:16 | number isn't important . Mhm . It's used when we | |
| 02:21 | say words like about or roughly we might say there | |
| 02:25 | are about this many or there are roughly this many | |
| 02:31 | . Okay , now that we know what rounding is | |
| 02:34 | and what it does , we need to learn how | |
| 02:37 | to round numbers . Let's pick a random number 46 | |
| 02:42 | . Before we do any rounding we need to review | |
| 02:45 | our place values . Do you remember place values ? | |
| 02:49 | It's important to know our place values so we can | |
| 02:52 | know exactly how to round the number . What digit | |
| 02:56 | is in the one spot ? Yes the number six | |
| 03:01 | . This first spot is always the ones spot . | |
| 03:05 | What digit is in the tens spot . Uh huh | |
| 03:10 | . The number four . The second spot is always | |
| 03:14 | the tens spot . Great job . Now that we | |
| 03:19 | know the place values , let's round 46 to the | |
| 03:22 | nearest 10 . You will always have two options to | |
| 03:26 | round up or to round down . In this example | |
| 03:30 | we will either round up to 50 or will round | |
| 03:34 | down to 40 . But which one do we need | |
| 03:37 | to do To find out ? We need to look | |
| 03:41 | at the digit before the spot . We are rounding | |
| 03:43 | to the digit before the four is six . If | |
| 03:47 | you are rounding to the nearest 10 , you always | |
| 03:50 | look at the one spot . Okay , Here is | |
| 03:54 | where we do the trick . If the spot before | |
| 03:57 | is five or more round up , let's say that | |
| 04:00 | again . If the spot before is five or more | |
| 04:03 | round up . All right . So the digit in | |
| 04:07 | the one spot is the # six . Are we | |
| 04:10 | going to round up or down ? Yes . Up | |
| 04:15 | . So this number will go up to 50 . | |
| 04:18 | That is the nearest 10 . We did it . | |
| 04:20 | We rounded a number 46 , gets rounded up to | |
| 04:25 | 50 . You did an awesome job . Let's do | |
| 04:28 | another one . Okay , how about the number 23 | |
| 04:33 | . What digit is in the one spot ? Yes | |
| 04:36 | , the number three . This first spot is always | |
| 04:40 | the one spot . What digit is in the 10 | |
| 04:42 | spot ? Yes , the number two . The second | |
| 04:46 | spot is always the 10 spot . Now that we | |
| 04:50 | know the place values . Let's round 23 to the | |
| 04:54 | nearest 10 . Remember you will always have two options | |
| 04:58 | to round up or to round down . In this | |
| 05:02 | example we will either round up to 30 or will | |
| 05:05 | round down to 20 . Next we need to look | |
| 05:10 | at the digit before the spot . We are rounding | |
| 05:12 | to the digit before the two is three , if | |
| 05:16 | you are rounding to the nearest 10 , you always | |
| 05:19 | look at the one spot . Okay , here is | |
| 05:22 | where we do the trick if the spot before is | |
| 05:25 | five or more round up , that's fun to say | |
| 05:28 | , let's say it one more time . If the | |
| 05:29 | spot before is five or more round up . All | |
| 05:33 | right , so the ditch it in the one spot | |
| 05:35 | is the number three . Are we going to round | |
| 05:38 | up or down ? Yes , down . So this | |
| 05:43 | number will go down to 20 . That is the | |
| 05:47 | nearest 10 . That's how you round numbers 23 gets | |
| 05:52 | rounded down to 20 . Great job . Let's use | |
| 05:57 | the trick on an even bigger number because it always | |
| 06:00 | works no matter how big the number is . Okay | |
| 06:05 | , how about the number 544 . What digit is | |
| 06:10 | in the tens spot ? Yes , the number four | |
| 06:14 | . Remember the second spot is always the 10 spot | |
| 06:18 | . What digit is in the hundreds spot ? Yeah | |
| 06:22 | . Yes , the number five the third spot is | |
| 06:25 | always the hundreds spot . Mhm . Now that we | |
| 06:29 | know the place values , let's round 544 to the | |
| 06:33 | nearest 100 . You will always have two options to | |
| 06:37 | round up or to round down . In this example | |
| 06:40 | we will either round up to 600 or will round | |
| 06:44 | down to 500 , but which one do we need | |
| 06:47 | to do ? Well , we need to look at | |
| 06:51 | the digit before the spot , we are rounding to | |
| 06:54 | the digit before the five is four . If you | |
| 06:58 | are rounding to the nearest 100 you always look at | |
| 07:01 | the 10 spot . Are you ready for the trick | |
| 07:05 | ? You know it ? Now , if the spot | |
| 07:07 | before is five or more round up , that's fun | |
| 07:10 | to say let's say it again together , if the | |
| 07:12 | spot before is five or more round up . Cool | |
| 07:16 | . Okay , so the digit in the 10 spot | |
| 07:20 | is the number four , are we going to round | |
| 07:23 | up or down ? Yes , down . So this | |
| 07:28 | number will go down to 500 , that is the | |
| 07:32 | nearest 100 that's how you round numbers 544 gets rounded | |
| 07:39 | down to 500 . Now , you know the trick | |
| 07:44 | to round any number if the spot before is five | |
| 07:48 | or more round up one more time . If the | |
| 07:51 | spot before is five or more round up . Great | |
| 07:54 | job . You did awesome special . Thanks to our | |
