This is a simple, but fun game for the ESL classroom. This game is similar to the "Teacher Says" game, but specifically for body parts.
How to play: Using the body parts that the students know, tell them to touch one body part with another. IE "touch your KNEE with your FINGER." The more body parts the students know the better. Once the students get the hang of it, let them become the teacher. Every now and then, say something that is very difficult to do, like touching your elbow with your tongue.
Variations:
In pairs get the student's to touch the other students body parts. IE "Touch you partner's knee with your finger." Only do this if the students are comfortable with it.
