"Become a Teacher" - A comprehension class game

Assign the role of the teacher to one of the pupils. The student who becomes teacher has to order in English his/ her classmates to do things. He/ She will start by saying the phrase; “I am the teacher! Please do what I will say."  Then he / she orders them to do what he/ she desires. For example "Touch your nose!” and  all the others will have to touch their noses or “Close your bags!”, “Open your books!”.  If the student does not begin by saying; “I am the teacher! Please do what I will say”, the others must not obey! Every student who becomes a teacher has to give only 3 orders. The game continues with the next student.
