I have tables, not desks. Each table had a bucket and everyone put their box of supplies in that bucket. It became time consuming to find their box...and if they went to a different area to work (like literacy stations ) then they would have to go get their box. I like the idea of them just being able to grab any old pencil. I plan on spending more community building this year and discussing the supplies. I am hoping this will alleviate the "I want that pencil!" type of stuff. I remember I had one girl who had to make sure her box was perfectly neat and organized before she came down to the carpet. She'd straighten that box out 3383874539 times a day.
