Roly loves hats, and they look great on him too! Have your little mathematician help this oh-so stylish cat count the hats in his collection by using his addition skills to make sure the right amount of hats are on the table. This game is a good way to have your kid practice representing addition facts with objects and it'll test her understanding of cumulative addition as she builds upon previous sums to satisfy Roly's need to keep tabs on all his hats.
