Thanks to one of coworkers, Danielle for the basic idea of this game.
Divide the students into 2 teams. Have 2 desks at the front of the class, facing each other, with an eraser in the middle of the 2 desks. One student from each team comes and sits in the hot seat. Rotate through so that all the students get a chance to play. You then ask a question of some sort. The first person that grabs the eraser can try to answer the question. My rule is that you can take the eraser whenever you want, but I"ll only say the question once. I then count 10 seconds down on my fingers. Their team can help them with the answer, but only in English. If correct, they get 1 point. If not, the other team gets a chance to answer the question.
This week in class, we're studying "When I _________, I ______/ I __________when I ________.
So, I would say something like, "When I feel happy, I _________." Or "I'm late for school when __________"
And of course, to make it even more exciting or if one team is behind by a lot of points, have a "Bonus Round," where the teams pick their best 3 players and each question is worth 2 or 3 points, or something like that.
