Your kids can stack up their riches into a three-dimensional penny pyramid that makes cents.

What You'll Need:

  • Several hundred pennies

How to Play Penny Pyramid:

Step 1: Have your children set out a square of pennies 10 pennies long and 10 pennies wide. Then have them make a 8 x 8-penny square on top of the original square, leaving the outside edge only one penny high.

Step 2: They should repeat the process with an 6 x 6-penny square, leaving the outside square one penny high, the next square two pennies high.

Step 3: Have them continue until the center four pennies are the highest, and then add a triangle of pennies to that layer. Then have them add a single penny in the center to top off the pyramid. Can your kids figure out how many pennies they used? Make sure they wash their hands before and after they play.
