Multiple-choice questions - A, B or C - on hallway and classroom behaviour, phones and headphones, homework and deadlines, punctuality, lab safety and dress code.
School rules are a topic every class already has opinions about, which makes them unusually good quiz material. The questions run A, B or C across the areas that actually generate arguments: behaviour in the corridor and the classroom, phones and headphones, homework and deadlines, being on time, safety in the lab, and what counts as dress code.
Nothing needs preparing. Play it, pause on each question, let students choose, then resume for the answer and keep score for teams or individuals; a fifteen to thirty second timer sharpens it further. A2-B1, and it earns its place as a bell-ringer, a back-to-school warm-up or a lesson left for a substitute.
