Allow for teachers to set a “room pass limit” for the amount of students who can leave their room at once and allow other students to get in line within a classroom. For example. If Sally asks to go to the bathroom, then Johnny asks right after her, and Marie asks rit after Johnny, they can still set up a pass to go, but it doesn’t start until the person in front of them comes back. This way, I do not have to keep a mental list and still allow only one student out of my room at a time.
