This product is designed for the muscle strength training of children with cerebral palsy. By pulling off the character parts on the cardboard teaching aids with your fingers, children are interested in the pattern and train their logic. In the process of separating the cardboard pattern, they train the coordination between the finger muscle and the hand eye, and then they piece together the missing role and follow the role to make specific actions, so as to achieve the effect of training different muscle groups repeatedly every day.
