Typically, I keep an entire unit in one box. I have a file folder for each day or lesson of instruction. On Friday, before I leave for the weekend, I take the file folders out of my box and put them in this hanging pocket organizer behind my desk (get a similar one here). That way, when I come in on Monday, everything I need for the lesson is right at my finger tips! I'll also add, that this is great if you are unexpectedly out sick one day. You can just direct the sub to follow the lesson in pocket!
What is your favorite method of organization? Have you tried the project cases? I'd love to hear from you!
