I would try as countdown to school, birthday or an advent cal. Question of the Day Calendar.small paper cups, a backboard to hold them, and numbered pieces of tissue paper to cover them. Could do a writing prompt for each day.
Milk crates zip-tied together on their sides so that a bench seat fits on top and red bins from Lowe's can slide inside them. I don't have any milk crates, though. I also don't know what "zip-tied" means. I would use different colors.
