Looking for a fun way to motivate middle school or high school students to keep their cellphones away? Look no further! This is an extremely effective cellphone policy for grades 6 - 12 that will improve student focus and learning in your classroom. I've spent the last few years perfecting this Cellphone Challenge; it not only keeps the phones out of sight but the students actually hold EACH OTHER accountable! I've encouraged my teacher colleagues to implement this and they have had major success with it as well. Included are editable posters for 5 or 6 class periods that you can customize with your own class names and rewards! To keep track of their progress you can use stickers, magnets, or simply draw in the box with a pen or pencil. Be sure to read the detailed instructions on how to implement this cellphone policy effectively to maximize your success. The posters are 8.5x11 but can be printed as a larger size by following these directions: Save the slide you want to print as a PDF. Open the PDF and click File > Print Page Sizing & Handling > Poster Tile Scale: 200% Overlap: 0.005 Another option is to have it printed at a larger size on a school copier or at an office supply store.
