Your kids are probably familiar with the empowering story of “The Little Engine That Could.” But what about the little shapes that could – hold up a stack of books?

In this exercise, your child will learn how to test the strength of different shapes. By making their own shapes and then balancing books on top of them, they can observe how strong each shape is. After they’re done, they’re going to feel just as determined as that little engine. Or maybe even that little square.
