Here's the Parallelogram song! It's a catchy tune!

FUN FACT:
The word polygon actually come from the Greek words polu (meaning many) and gonia (meaning angle).
We used everyday items (straws and twist ties) to practice geometry |
a square is defined as a rectangle with all sides equal in length |
a rhombus--a parallelogram with all sides equal in length (a square is a special type of rhombus) |
What can you make with straws and twist-ties?
In math class, the possibilities are endless!
