These files are for racing/car themed classroom. Use them for students to return finished work and unfinished work. I would suggest printing and glue to a manilla envelope and laminate. Use the space provided on the "Finish Line" sheet to write the assignment down and have student turn them in to the envelope when completed and they cross out their student number on the front with a wet erase marker. You will know immediately who has not finished work by looking at their number (racing flag). One file is red and one is blue. I use these in my third grade class and designate on color for morning class and one color for my afternoon class. Also, use the "Pit Stop" file for students to put any assignment that they have not completed. They circle their number and I train them to go to that folder/file as they have work time to finish anything. No losing papers in a messy desk/binder/or tote tray!
