This activity requires very little prep. All that is needed is a deck of regular player cards and a copy of the reference page. Students can play in groups of two or three.
Once cards are dealt, payers flip over their top card. The player with the highest value (ace is low, king is high) locates the subject/infinitive that corresponds to that card (3 of hearts, king of diamonds, 4 of clubs, 7 of spades, etc.) on the reference sheet and says the correct verb form in French. For more of a challenge the students can be required to say a complete sentence with the verb form. He then takes the cards and adds them to his point pile.
Once the deck is used up, all players count the cards that they placed aside and record their scores on a sheet of paper. All the cards are reshuffled and play continues.
The teacher can decide the end point. (Go through the deck two or three times, first player to 30, 40, 50, 60 points).
