Use 2"x4" white shipping labels (Avery 5263). Print red and white labels. Use the Monday through Friday to organize the work that your students will use this week. When you are copying items for future use, put them in the container marked "Next Week's Work" or "Future Work". As you bring master copies back, put them in the "To File" container. After you grade the papers decide if they need to go in "Cubbies" or "Portfolios" with these file labels. I have some other colors available. Need different colors or different words? E-mail me! I will have a you tube in mid July to show you how I use these!
