This unique set is designed to grow children’s confidence and critical analytical thinking skills as they build and solve puzzles—no reading required! Packed with puzzle cards that increase in difficulty and are designed to be completed in chronological order, the set challenges kids to find tiles of a particular shape, size and color…place them on matching shapes within a bubble…then maneuver the tiles to build images outside the bubble. Set includes 30 puzzle cards, 32 shape tiles, a sturdy storage tray and a starter guide; each card measures 5" x 7 3/4".
