As described on my schoolroom page, each of my guys has a shelf with their drawers and materials. I use adhesive velcro dots to place a label on each drawer and these may change from day to day since they only have 6 drawers each. Also, I've decided to only do science twice a week and history twice a week, so those drawers flip flop each day.
As I write this we are only two days in and so far the boys aren't using these drawers very independently in terms of "working through" them. However, at this stage I am wanting to sit with each of them, especially as they do their core subjects, so I can assess where they're at and then determine what might be most appropriate for them to begin to do on their own.
For now, I'm using some pieces of cardstock that I laminated to write their "assignments" on, and I place these in the corresponding drawer. These can easily be wiped off each day and reused.
In the above photo you can see one set of my oldest son's drawers. In the photo below, you can see his "assignment card" along with the necessary materials (in this case, his Reading A-Z book and science notebook).
I guess you could say that for now we are mostly using our "workboxes" to organize their work instead of as a system to increase their independence. And for now I'm fine with that. I really like having a designated spot to put all the materials they need for each day. It seems a lot easier to break that all down by subject instead of having it all glopped together somewhere in our schoolroom. The drawers are not wide enough for all my teaching manuals, but for the ones that fit, it's nice to be able to stick the manual in the drawer along with a paper-clipped assignment card. So far, it hasn't been taking me a whole lot of time each night to get the drawers ready for the next day.
