This game should take up an entire class period. Divide students into teams. Teams take turns choosing a question (1-54). If they answer correctly, click and a box with a question mark will appear. Click on the question mark to reveal how many points the team has earned (1, 2, or 3). If teams select one of the stars, they get to steal 2 points from another team. This keeps the game fun, because one team cannot get too far ahead and even teams that don't know much have an opportunity to get points.
By the way, this is a hybrid of a few different PPT games that I've found on teaching websites. Special thanks to those who designed the templates for "The Monster Game" (available on EFL 2.0), "Star Power" (waygook.org), and "BAAM."
