Pattern Recognition set helps children discover rules to predict sequence and further develop logical thinking, and early math and reading skills with pattern cards. A great exercise for increasing brain power. The challenge begins when a child pulls a card and begins to duplicate and fill in the missing pieces of the pattern using the tray and tiles to complete the pattern. Set includes 60 illustrated tiles, one tray for tile placement, 40 cards that are printed with three levels of difficulty and an instruction booklet with solutions and the rules that explain them.
