Have your Students put chairs into a circle and then sit down.

As the teacher you stand in the middle.

Say to them "If you are wearing ………, change your seats".

The children wearing the item of clothing you mentioned should then get up and change places with another child who is also wearing that same particular item of clothing.

Other suggested statements are:
- If you have long/short/black/blond hair / brown / blue eyes / a brother
- If you like...
- If youwant...

WARNING. This can be a dangerous game if several students rush to the same vacant chair or if students pull chairs away from class mates before they sitdown.
