I play Star wars Dodgeball, where all the kids have a ball each and throw the balls at the other team.

The first team to have all the other team sat down wins. When a player is hit, they must sit down. One person on each side is a secret Jedi Knight and has the power to touch his team mates who are sat down. Once he has touched them, they can rejoin the game. Teams have to figure out who the jedi is on each team, as when the jedi gets hit by a ball, nobody else can be saved.

Best game in the world ever, kids absolutely love it and always ask me if they can play it whenever I am at the school.
