Imagine a physical education (PE) lesson where a game of ‘dodge ball’ is on the agenda and the teacher starts the lesson in the following way:Teacher

Today we are going to cooperate in different ball games; that is to say, we will do some cooperation activities in conjunction with playing ball games. We’ll form two teams and the players in one team have to throw the ball and try to hit the players in the other team. If the ball hits someone’s head, it doesn’t count. One team has to try to beat the other team by throwing the ball at somebody – dodge ball. In short, the aim of the game is to cooperate.
