This game is flexible and can be run in a variety of ways: - Teams could choose questions individually, with the opportunity for the other team to ‘steal’ if their answer is incorrect. - A whole team may complete a question with one student being chosen to provide an answer. - Individual students from each team may compete simultaneously for a quickest answer. - Red/Blue team students can be paired. The teacher can then either assess which majority of a team got their answer correct fastest (using mini-whiteboards) or poll the class as to how many red/blue team members won within each pair, and therefore determine the overall winning team.
