Mark out a playing area as large as a basketball court and spit the class into two teams and give each team an even amount of dodgeballs.On the whistle the class starts throwing the dodgeballs trying to hit the opposite team, the players cannot cross the centerline. If a player is hit, they must go to their teams' jail and wait to be set free. Meanwhile the referee holds the Powerball, a larger or different colored ball. Occasionally during the game, the referee will roll the ball along the centerline. Players have 10-15 seconds to retrieve the ball and get it to the referee without getting hit. If they are successful one of their teammates who has been in jail the longest get to return to the game. The games ends if one team has all their players in jail. Leaving the other team, the winners or the referee calls time and the team with the most players standing would be the winners.
