Part of managing your classroom is regulating when students leave the room. Restroom passes encourage students to budget their restroom usage.
These restroom passes limit the amount of times that students can take away from class time and use the restroom. If students use their time wisely, and miss less time, they are rewarded with extra credit for unused passes.
I have students glue the passes into their notebook, and the "Restroom Manager" (class job), stamps the pass when a student uses it. At the end of the marking period, they receive bonus points for unused passes.
Included are 8 passes for up to 6 marking periods.
