Polygon Vs Quadrilateral
By google infinite
A polygon is any 2-dimensional shape formed with straight lines. Triangles, quadrilaterals, pentagons, and hexagons are all examples of polygons.
How to Find the Area of a Triangle
By eHow
In this video learn how the area of a triangle can be determined by multiplying half of the base by the height as a triangle is essentially half of a quadrilateral shape. Calculate the area of a triangle with instructions from a college-level math teacher in this free video on geometry. Narrator draws examples on a whiteboard with marker.

Students learn the definition of a polygon as well as the definitions of concave and convex polygons. Students also learn the following polygon classifications: triangle (3 sides) quadrilateral (4 sides) pentagon (5 sides) hexagon (6 sides) heptagon (7 sides) octagon (8 sides) nonagon (9 sides) decagon (10 sides) dodecagon (12 sides).

3rd Grade Math Rap
By McCarthy Math Academy
With a little help from the group, Mindless Behavior, I have created a math video with lyrics to help my students to understand and apply core math skills for third grade. People of all ages can jam out to this one. Enjoy!
I've got a case of the operation blues.
Because I don't know which one I should use.
Look at the word problem for the clues.
The key words tell you how to choose.
Each means you multiply or you must divide.
Tryna find the total? Then you multiply
Total's in the problem? Then you must divide.
Not quick to solve it, draw it, get it right.
Addition's easy for me and you
Sum, In all, together, and total too.
When do you subtract? How many more?
Fewer? Left? Less? Difference in a score?
Place value's next. Disco on the " dess "
Ones, tens, hundreds, to the left
Thousands, Ten thousands, hundred...thousand
Say the name of the place, yeah.
The value's the amount of the place
For example, 2,060.
The value of the 2 is 2-0-0-0,
The value of the 6 is 6-0.
When you round, find and underline the place
Spotlight to the right, decide the digit's fate
5 or more, add 1 to the rounding place
4 or less, do nothing but walk away, (estimate)
A pen, penny is one, one cent
A Nic-kel is five, a dime is ten cents
25 for a quarter, George Washington
100 cents makes a dollar, there he goes again.
For pictographs, you gotta check out the key
One smiley face might really equal three
For bar graphs, pay attention to the scale
Think it's counting by ones, huh, you'll fail
Fractions are easy, just draw your best.
Here they go from least to greatest
1/12, 1/6, ¼, 1/3,
½, 2/3, ¾, Fraction nerd!
You see that number on top,
That's called the numerator
It describes the amount
That is being considered
And if you jump down from the fraction bar
Denominator
It's the total number of equal parts.
Let me give you an example:
Leslie Moin has some coins
A total of 9
2 happen to be pennies
While 7 are dimes.
What's the fraction of dimes?
How many coins? 9
How many dimes? 7
Say the fraction -- seven ninths
Length times width is Area
Distance around is Perimeter
Break down the GEOMETRY
3 sides makes triangle
4 sides = quadrilateral
5 pentagon, 6 hexagon
8 octagon, 10 decagon
Lines that never cross - PARALLEL
Lines that meet or cross - INTERSECTING
Lines that form right angles -- PERPENDICULAR
Same shape, same size -- CONGRUENT
Line that cuts in half - SYMMETRY
Up and Down - VERTICAL
Left to Right -- HORIZONTAL
An angle less than right - ACUTE
An angle opened wide - OBTUSE
Ninety degrees square corner - RIGHT ANGLE
Back to triangles
3 sides the same = equilateral
2 sides the same = isosceles
no sides the same = Hey, that's a scalene right!
So, that's it.
That's our math song.
Before we leave,
Remember to read
Your math problems three times before you answer.
That way you know what the problem
Is asking you to do.
Don't be lazy, be brilliant.
Piece! Like a fraction.
