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. Best of all, the metal tin’s lid doubles as a work surface—the puzzle cards stick to the tin with the powerful magnet on the back of each shape tile! Set includes 30 puzzle cards, 32 shape tiles with magnetic backing, a cloth storage bag, a sturdy metal tin with a lid and a starter guide; each card measures 5" x 7 3/4".
