A non-carpeted floor is the best surface for this game. Divide the students up into two even teams and have each team choose a goalie. Have the goalies sit across from one another at each end of the playing area. These are not traditional goalies, their job is to get the balloon and sit on it before the other team counts to three (loudly). The rest of the players all have their own chair that they can not get out of. The game style is similar to soccer but each player moves around the room in a chair and uses their free hand to hit the balloon and their other hand to hold onto the chair. The teams play offense and defense and score when their goalie (who is on the other end of the playing area) pops a balloon. Note to leader: have each kid blow up one balloon before you get started, the game moves fast.
