Mark out a playing area about the size of a basketball court, with a marked out center line and slit the class into two teams. Place all the dodgeball along the center line and all players must stand on the end line. On the whistle the players run up to the dodgeballs and start throwing them at the opposite team (without crossing the center line). If a player is hit, they must go to the other side (become a Traitor). If a player catches a dodgeball the person that threw it must go to the other side. The games end when all players are on one side (the last person to be hit would be the winner) or the referee calls time and the side with the most players would be the winners.
