Age: Preschool-1st grade
Math: Sizes (relative to one another)

An incredibly simple and comical way to look at sizes when compared to one another. From these two opposite creature's perspectives, they see themselves as the norm. When they meet each other, they believe the other to be different. The big guy declares the small guy as small and vice versa and both try and refute the other's declaration. Until one enormous hairy foot and one little creature appear to provide perspective. Nothing is ever absolute when comparing dimension!
