The Preschool Puzzler, model 7131, is a three-sided puzzle with large pieces designed to teach beginning matching skills to children with physical, cognitive, or neurological disabilities. The child must match plastic pieces to the corresponding hole by color or shape before the timer on top runs out. If all three sides are not complete and the timer is not stopped in time, the puzzle flips open and the pieces fly off. Puzzle pieces come in the shape of a heart, star, moon, square, duck, bear, and cat. COLOR: This puzzle has a white base, a red, white, blue, and yellow timer, and red, green, and blue side panels. Puzzle pieces are light blue, yellow, dark blue, red, green, and white.
