Teach a few French professions, course names/school subjects, and avoir. A "quiz and trade" style game in which students show a partner a profession and say "Je suis actrice". Their partner responds with school subjects they have, in order to do that job "Tu as danse, theatre, et chorale".
There are 16 professions (actor, archeologist, painter, translator...) and with duplicated you can easily accommodate a large class. Plus the duplicates allow them to practice the plural forms "Nous sommes actrices, nous avons danse et chorale"
Full directions on the Power Point.
Geared at Allez Viens 1, chapter 2.
Game assumes that school subjects have been taught.
Could easily be adapted to any other language, just change the profession names.
