Avoid all those sticky notes left on your desk (and messy drawers because those sticky notes were apparently super hard to find!) and use this form when you need a sub for the day.
Only have 3 or 4 class periods? Just delete a box or two and resize what's left! You can easily edit the headings in the colored boxes to represent subjects, instead of class periods. And printing in grayscale can save your printer ink when color coding isn't necessary...which I think is NEVER but that's for another day!
