Have five minutes before break time that you need to kill? Enter Sumo, the most fun your kids will have all class. And the next class. And the next.
Seat your students in a large circle to function as the ring. Divide the class into two teams. One student (wrestler) from each team enters the ring and stands face to face with the other. Not too close together. A meter is or more is ideal.
Both wrestlers put their hands behind their back in a way that they can hold a flashcard (put there by you), keeping it hidden from their opponent. Put one minute on the clock. The point is for students to maneuver so that they can see their opponent’s flashcard and call it out before the opponent sees theirs.
Students aren’t allowed to use their hands for anything but holding the flashcard, nor are they allowed to talk unless it’s to call out the flashcard. The other students are only allowed to cheer on their teammate (they’ll often try to cheat by telling their teammate what’s on the opponent’s flashcard).
Sumo isn’t the most communicative game in the EFL/ESL teacher’s arsenal, so use it sparingly and never at length. But when it comes to killing 5 minutes, except no substitute.
