This is a simple game that has students practicing which verbs use avoir to conjugate the passe compose/past tense and which use etre.
Students can be by themselves, or in groups. Each group/student is given two sheets. One is split into two sections: Avoir and Etre. The other has a bunch of different verbs in the infinitive. They must cut out the verbs and place them in the correct category.
This is great played as a game, but also works for centers if you do those as well.
