Area Antics

This popular activity plays like the card game “War”, but with a new twist. Players estimate, and then measure, the area of shapes by covering them with centimeter blocks. With practice, they internalize the concept of area and learn to estimate it. This activity can also be used to learn about perimeter. Adding more layers of blocks introduces the concept of volume.
