This educational card game is truly amazing! There is always one, and only one, matching symbol between any two cards. Spot it to win! As they search for matches, preschoolers will learn to identify numbers and geometric shapes, the building blocks of math. Color recognition is also developed, as the matching symbol needs to be the same color. Spot it! Numbers & Shapes is the perfect first math game for preschoolers!
