Set up two poly dots approximately 2m apart. Two children face each other on either side. One child has a ball and the other doesn’t. The child with the ball’s objective is to place the ball on top of a dot with their foot on top. The other child is trying to put their foot on the dot before the attacker can put the ball there. The attacker can then try to get to the other dot or fake one way and go back etc.
Encourage sideways movement on toes instead turning whole body in that direction.
