Here is a management tip that I'm sure ALL of you already use! Each of my students have one pencil in their own pencil box. If their pencil breaks, they may put it in the "broken pencil" box and get a new one from the sharpened pencils (without asking me). Anytime they find a pencil on the floor, they can put it in one of the pencil boxes based on if it's broken or not. I'm sure you already do this!
