Preschoolers can count on fun with the Adding Alligator learning toy from Fisher Price. Designed to introduce numbers and early math concepts using blocks and stacking play, kids can explore adding and subtracting by stacking the numbered blocks up to ""feed"" the alligator. When they slide the alligator's head down, it stops on the top block, and the correct sum of the numbers is revealed. Kids can try adding different number combinations, or they can remove blocks to see how subtraction works. Blocks stack on the base for easy storage. Colors and decorations may vary.
