Hey, how do I download it?
This is a warmer, and there is nothing to download. It's just an idea for your lesson, not a worksheet.
Students work in pairs or small groups, making different noises with their mouth - the partner or the rest of the group should guess what this person is doing. 'You are yawning!' 'You are kissing your Mom good-bye!', 'You're snoring!', etc.
The teacher should first demonstrate the activity to make sure the students have had a laugh at you and are not too shy to make funny noises themselves!
