I have included two versions: a black and white version and colored version.
I like to give my students 3 each 9 weeks. These passes are their only way out of the classroom (to go to the bathroom, get something out of their locker, etc.). Students may also use these passes to replace a homework assignment. Using the passes this way has cut down on students asking to leave the room; they don’t want to use their homework passes unless they really need to go.
I like to print the black and white ones on colored paper so that it is harder so students to copy them.
