Where to put their work???

My next planning task is deciding where to put the work for them to choose from when I have enough work for work time. I saw that at 1+1+1 she is using the workbox system which is really a cool idea but I have 20 little lovelies so that will not work space wise for me. I found the most adorable little trays at Dollar General and couldn't resist. Will post a picture soon. They are the perfect size for most of the work. I bought every one that I could find at all the area stores and they come in four different colors that almost match my group colors. They have blue, pink, red, and green and my group colors and blue, purple, red and green. My room is organized into activity centers versus subject centers so this is going to be the challenge. I currently have a magnetic center, a drama center, a pocket chart center, a DVD center, and a computer center, all other tasks are done on the carpet or at tables. I am thinking of just placing the work for now on top of my bookcases and changing out between language and math work times for now.
