I looked at him suspiciously and said okay , I will see what I can find. The next day I brought in the box top and asked him to show me how this will work. He put his binder and materials into the box top and put the box into the desk.
I looked at him and said how will this help. He said he has two reasons it will work. The first one is that because the box top blocks the opening, he can't just stuff his papers into his desk. He has to actually open slide out the box top to put papers and pencils in. Also because he is sliding the box out it reminds him to put the papers in his binder. He also said that since we move our materials around to other desks he will be able to take the box top out and just move it .
So he began using his system and sure enough the organization became much better. His technique also spread amongst the class and now many other students have their own box top in the desk. For those chronically disorganized it is worth a shot. A free desk organizer sitting in the paper room.
