Sure. How about the following game 10 minutes before school ends.
All students stand in a row in front of the board. The first 5 students stand in front of a buzzer. The teacher asks a question. Whoever buzzes is allowed to give the answer. If it is correct, the student gets to go home. All other students have to line up at the back and the next 5 students move to the buzzers. If the answer is wrong, that student has to stand in line and the remaining students can buzz. If no one knows, the next 5 students step up to the buzzer.
