When teachers arrange their desks in groups, they need an easy way to label each group. Many teachers number them, or gang things from the ceiling using string, but the following idea was the easiest to set up and most easily recognizable table identification system I’ve ever seen. It’s so easy that it blows everything else out of the water. Take a solid piece of construction paper or cardstock and fold it in half. Then tuck one end in the metal bar between ceiling tiles. Done. Anyone with half a brain who walks into the room will know what color goes with each group of desks and it’ll take you 2 minutes flat to put up all the papers. Just make sure your school doesn’t have any fire codes you’d be violating if you attach anything to the ceiling…
