Each student gets a pencil and a paper. On the command "GO!" the students start walking around in the classroom. When the teacher says "STOP!" the students have to pick a fellow student who stands close to them. The teacher asks a question which the students have to answer with their partner. The students write down their answer on the paper. Then the teacher says "CHANGE!" and each student has to start walking around in the classroom again until the teacher says "STOP!" again. The students have to pick a new partner and answer a new question. This can be repeated over and over again.
