This team activity can be space demanding especially if you teach a large class. But it is very easy to arrange the classroom for it. You just need to divide students into two groups and place two chairs in front of them. One is marked true and the other one false. Only two students compete against each other at the same time. Read one statement from the list. Students must be quick in reaction and sit on a correct chair according to the correctness of the sentence. If you say that "The sun is black.", correct reaction is to sit on the false chair. The only thing they need to do is to listen and comprehend correctly. Then another pair takes turn .
