Her system is to keep a sheet of mailing labels on her clipboard, keep running notes on the students as they work, then afix them to notecards to keep handy for conferences, etc - great idea!
So what I do is keep file folder labels (they fit well in the note space of my Student Record forms) attached to my clipboard, then stick the labels into the file folders. Brilliant! Not only do I not need to worry that I'll forget to record something of importance, but I also find that I'm making many more notes. I am especially getting many more "good" notes into student folders, rather than simply documenting discipline or off-task notes.
