Hockey Tag
A selection of children are chosen to be the "taggers".
Each other child in the class has a hockey stick and ball, they dribble the ball into space trying to avoid the "taggers" who are trying to knock the ball away from the player. If the ball is succesfully taken away by the "tagger" then the the children's role is reversed.
Another variation is to collect the ball and wait for someone to free you by passing the ball between your legs.
