I am using these for all those papers that are graded and waiting to be handed back. I bought scrapbook paper from Michael's and used my silhouette to cut out the numbers for the periods (5th is my conference period). Then I used Modge Podge under the paper then over the paper. I may end up giving it a few more coats so it can stand up to high school kids.
How do you organize graded papers? Did you see Chonte's Math Classroom post? Did you see her paper organizer? Are you jealous? She has the best finds.
