Mark out a playing area as large as a basketball court and places a mat or tarp at each three-point line. Slit the class into to two teams and have each team strand on their teams mat or tarp, with even amount of dodgeballs each. On the whistle they start, players must stand on the mat or tarp to play. Only one player at a time may step off to collect dodgeballs, but they cannot throw them unless they are on the “island”. Players keep throwing the dodgeballs trying hit the opposite team, if a player gets hit, they must sit down and stay sitting until the game is ended. The game ends when all the players from one team are sitting down. Leaving the other team as the winners.
