Single layer, 8-piece meticulously cut wooden puzzle, Rainbow Fish invites exploration of color and shapes. Puzzles develop eye-hand coordination, fine and gross motor skills, memory, spatial relations, problem solving, patience, and persistence. With only one way to complete the fish-shaped puzzle, the toddler must sort out and make sense of the pieces, then work out how the parts go together to create the whole, a sometimes frustrating experience that benefits from parental encouragement. Puzzle measures 6″ square. Colors are non-toxic, eco-friendly, water based paints.
