Mark out a playing area about the side of a basketball court with a marked out center line and place a hula-hoop at each three-point line, slit the class into two teams and get each team to pick one player to be the Jedi. Jedi's start the game inside of a hula-hoop which is their “circle of force”. On the whistle the players start throwing dodgeballs at each other (without crossing the center line). When a player is hit, they must sit down. The Jedi's can heal them by tagging them. If the Jedi has to come out of their “circle of force” to heal someone and they get hit by a dodgeball they are out. Each player that gets hit after the Jedi is eliminated goes out as well. Once a player, or Jedi is out they cannot return even if someone catches a dodgeball. You can give the Jedi a lightsaber (foam noodle) to carry. They can use the saber to tag their fallen teammates. This gives them a bit more reach from their “circle of force”. The game ends when one team has all their players sitting down making the other team the winners, or when the referee calls time, the team with the most players standing would be the winners.
