This is a great game for quick conjugation review. Regular preterite, ser/ir, and "-car/-gar/-zar" verbs are included. Each student is given a game sheet with infinitives and subjects. They have to "race" their partner to get the best time. You can either use a timer online and project it on the smartboard/screen or give students individual timers to use. When they think they are finished, they write the time that it says on the timer down. They switch papers with their partners and for each wrong conjugation they have to add 30 second to their time. At the end of the game, the player with the lowest time is the winner. Students always love this game and it gets very competitive!
