The way I play this vocabulary game with my AP Government class is that I place students into heterogeneous groups. In groups, one pair at a time will come up to the front of the room to be in the "hot seat." One student will be facing the board and the other student away from the board. They will need to describe an APGOV vocabulary word without saying the word in their description. The student facing away from the board will have 15 seconds to answer.
While the pair is playing, I have each group write one detail they know about the topic on the white boards (beyond the vocabulary word). This game is awesome and my students love it.
