This set of 25 colorful two-piece puzzles helps kids master early counting and number recognition skills through brain-teasing puzzle play. Each matching puzzle features one number from 1 to 25 on one piece and a corresponding number of illustrated animals and items on the other. Designed with little ones in mind, each puzzle is self-correcting, which makes it easier for kids to puzzle out the one right answer. Each set comes in a sturdy reusable box that doubles as a storage container.
