Spot it. Numbers and Shapes is a fun and rewarding way for preschoolers to learn their one, two, threes and the shapes that inhabit our world. There is always one, and only one, matching symbol between any two cards. Spot it to win. Symbols include the numbers 1 through 9 and basic geometric shapes such as squares and circles. As they search for matches, little ones will visually and verbally identify numbers and shapes, the building blocks of math. The matching symbol needs to be the same color so color recognition is also reinforced.
