This activity is a great supplement to D'Accord 1 - Unité 7 - Chez nous or D'Accord 2 - Unité Préliminaire
Choose 9 volunteers to come up to the front and give you all of here and identity card. The rest of the class now uses the handout to try to guess the identity of the students at the front. They can ask one question of one student at a time.
Ex: Est-ce que tu parles russe?
Everyone needs to be listening to all the answers to help them narrow down the search. If the student is ready to guess he or she will ask: Es-tu Claude?
To make the game even more challenging, I sometimes hand out 8 cards out of 9, and have 8 volunteers. That way, they have to figure out the missing person as a bonus.
