The Hammer Bench and Balls comes with 3 coloured balls. The child must place them on the rubber holes in the bench and then hammer them until they roll down the ramp and out onto the floor. They retrieve the balls and repeat the activity.
For a younger child I would initially remove the hammer and allow them to push the balls down with their hands. Quite a lot of strength is required to do this! Strengthening of the hand is vital for later activities such as writing. The small ramp allows the child to practise eye tracking, an important skill for reading later on.
