Have students fill out this form and hand it in as a replacement for the assignment they aren't handing in. Then, cut off the bottom and put it in a green pocket on the wall. The next day, pull all slips and call for late work and parent signed late sheets. If they don't have them, move the slips to the yellow pocket. Do the same the next day. When slips are in the red pocket, students call home with me there to tell their parents what the situation is. It works, and it relieves the teacher of a lot of extra recording. I have added the flow chart as well to help students know what they are required to do.
