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 puzzle, the child has to 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.
