Let me let you in on a little secret. You are going to LOVE this website:
busyteacherscafe.com
This site is filled with forms, calendars, monthly themes and tons of additional resources.
My favorite part of this website though, is its ability to type right inside calendars and forms and simply print them off - ready to use!
For example, I can open up the calendar for March and type in students names for helper of the day or sharing schedules, classroom events, etc and print it out. No worrying about saving the file first or messing with formatting settings! (Printables --> Management & Forms)
Serious, check it out! It's defiantly a time saver!
