This one will be a series to help organize all the papers that come into your room.
The bins in my room help to collect he papers that come in and go out.
1 - Student homework or notes from parents go in a metal flat bin by the front door - it is labeled homework.
2 - Since 3 teach different grades, I have three bins on a shelf by my desk for work to give back to students, labeled for each grade.
3 - Students in my middle school classes are always looking for loose-leaf and I hate when they tear it out of a book or binder, so I keep a bin by their work material just for loose-leaf.
Try these three for organizing papers that come through your door.
