Can, Shoe and Dot Organizers
I save tin cans to use as supply sorters. I clean them out, remove the labels, file down any sharp edges and paint them. They can be glued together or put in the same tray to organize pencils, rulers, pens, etc. Over the door shoe racks are great to use for puppets, mail, make-up work or lost and found items.
I keep an inventory of my personal belongings using forms from Microsoft and colored dot stickers. Whenever I bring in a book, CD, or video from home, I record it on my form and stick a colored dot on it. The dots are easy to spot even from across the room.
