In childhood, new objects, events, and people are constantly encountered. Children must develop the cognitive ability to categorize to manage all of these new experiences. This set of 144 realistically-illustrated picture cards delivers concrete practice in this fundamental building block of learning.

Set includes 17 categories with 6-10 cards in each. Teaching notes include activities ranging from simple categorization to identifying items that do not belong, creating sub-categories, and mind-stretching go-together riddles.
