Do As I Say, Not As I Do

Pick one of your students (the leader) to stand at the front of the classroom while the rest of the group stands in an open space facing her. Tell the leader that she must try and confuse the other students by telling them to perform one action while she acts out another. For instance, while she tells the students to bounce on one foot, she rubs her stomach. The students all have to perform the action she tells them to perform. Any time a player performs the same action as the leader, he gets eliminated from the game. The last person standing, having only performed what the leader said throughout the game, wins.
