I did most of my actual planning earlier in the year. I made a sheet for the boys of their daily work and put it in a folder. Then I take out a week's worth of folder's and put it on top of one of the drawers. They are responsible for getting all of their work done. I do help them with their Math and Science.
For my daughter, I put worksheets in her daily folders. Then, I just pull out the worksheets for that day. If there is something new on a worksheet then we go over that first thing. Then, I let her do a few worksheets at a time until all have been completed. I have found that this works best for her.
