Area of a Triangle Hats

Why not have fun while learning Geometry formulas?

I decided we needed to turn the rather long and wordy formulas into a more fun and exciting activity… so we made Party Hats!!!

The formula is written inside the triangle.  As we put them together we would sing a song about the area of a triangle and then we danced and marched around the room.

Lots of fun!
