I know this has been addressed before, but I don't remember where...anyhoo...Do you number your students? If you do, what do you do when you have a student move away or have one move in? Do you give a new student an old number? I don't want to switch numbers around since that would be too confusing. Also, when a new student moves in, do you put them at the end of your class list or do you put them into the abc order???
