sign up (free!)
Students sign out when they leave the classroom; can also have magnetic pictures/words for nurse, bathroom, etc. so students can put it beside their name so you know exactly where they are.
work boxes, have one for each student, when they finish their work they can go to their work box and pull out things to work on that the teacher has placed in there. (lets the teacher assign different things for the student/if they need extra practice in an area) - DIFFERENTIATION!
Sub Tub... great to have in your classroom to be prepared for when you need a sub. Contains a Welcome Binder explaining the daily schedule, where things are in the room and anything the sub might need like computer log-in codes. Tub also has hanging folders for each day of the week with emergency lesson ideas, great books, games and other activities to do!
