Idk about the future, but we used to do like 10 math problems at the end of class, and they were supposed to be finished by tomorrow, where we would review them. It’s a day of margin only, we did have 10 mins to do most of them, and lazy people like me did them in recess right before class. The teacher didn’t check them 1 by 1, but if you were picked to present the problem in the review and you didn’t have it done, you were fucked.
