The point

This is a point.. This point does not want to be a point so it decides to chang.

This is a line. The point that became a line doesn’t want to be a line anymore. So it decides to change.

Here is an angle The line decided that he doesn’t want to be a line he wants to be a …

Triangle. This is a triangle. Triangles don’t like being triangles because there are too many triangles in the world and that it is not special if there are a lot more of what you are. So he decided that he would change to some thing else. He wants to be an equilateral.

This is an square Being an equilateral is not fun (don’t ask why I don’t know I have never bin one.) So he decided to change to a parallelogram.

This is a parallelogram. Parallelograms are funny looking nobody wants to be one so he decided to change into a trapazoid.

This is a trapezoid Trapezoids look like up-side-down skirts I sure do not want to be that. So he changed into a pentagon.

This is a pentagon. Pentagons don’t have enough sides so he decided to change into a hexagon.

This is a hexagon Hexagons have one more side then a pentagon that is getting better but I think we still can have more sides so he decided to be a heptagon.

This is a heptagon Heptagons don’t look like some thing I would want to be so he decided to be an octagon.

This is an octagon Octagons are to comon I want some thing that is not nor

Multiplying by 10,100,

10 If you have a ten and you multiply it by a 6 all you do is take the 1 off the ten and add the number you are multiply in the ones place. 6 x 10 = 60 2 x 10 = 20

100 When you are multiplying by 100 you do almost the same thing as you do when you multiply by 10. But when you multiply with 100 you add a zero. You take the 1 off and add the number you are multiplying by. 8 x 100 = x 200 = 8,000.
