Who are you?

Assign each student a secret identity (or allow them to choose one). These might have to do with a particular topic, e.g. jobs, or just be famous people of their choice. One at a time, the students enter a ‘party’ and start chatting to each other (in pairs / groups). The goal is to determine the identity through asking general questions (e.g. Where do you live? What do you do? What do you like doing?).
