To keep myself organized, I designed a notebook to use with each of my 4 classes. There was room for planning as well as class notes (I found I wasn't using my separate planning book very much), learning targets and justification, and graph paper. Each week I would scan the notes for the class web site, which parents and absent students appreciated.
At the end of the year one student asked if he could keep The Notes. Why not?
A few colleagues (not just in math) also used the notebook this last year and offered improvement suggestions. I made 18-week and 36-week versions:
