Do you ever lose planning time to cover for another absent teacher in your school? Is that preparation time owed back to you under your collective agreement? If so, it's in your best interest to track those lost prep periods as well as when they are paid back.
I made this freebie for my own personal use when the sticky note system I had was overflowing in all directions, and I thought I'd share it with other teachers who might have the same arrangements. Print off a copy or two & place it in the front of your planning binder, or even tack it to a bulletin board near your desk.
If you like it, leave me a little comment please. If you have suggestions, I'm always open to those as well.
