Dodge Ball
There are many versions of dodge ball. Here is a great one for more confined spaces. Have the kids line up in a large circle. Designate a small circle/square inside. Put one group of kids in that area. Kids in the outer circle try to throw the balls (I advice you use foam balls or even beach balls) at the kids in the inner circle/square. Once a child is hit, they have to leave the game. Hits to the head to do not count. Once the first inside group is eliminated (or at set time intervals) put a new group of kids in the center circle.
