A friend of mine, who works as a teacher, told me about this great idea they have for class. Whenever a student misses class for whatever reason, they have this folders panel attached to the wall, with the name of each day, from Monday to Friday, so, if there was any homework for a given day, they could come and collect it from there.
Of course this was before the Coronavirus outbreak, but I still think it was a neat idea to organize things.
