Cut out the players, the balls and the nets or hoops.
Paste the player on one side and the net on the other side of a horizontal piece of card stock. Laminate.
Add 5 or 6 pieces of velcro to the laminated card stock...making a path between the player and his net/hoop.
When the child does a wanted behavior, make the ball advance one velcro at a time. When the ball is in the net, the child receives a prize or reward.
