We've all been there: you're in the midst of a discussion, when a student's hand goes up. You call on the student, perhaps a bit too eagerly, fully expecting a question worthy of your fascinating, expertly-led discussion...only to have them ask to go to the bathroom.
Well, no more embarrassing moments like these or wasted class time when you put students in charge of their own bladders with these finely crafted, all-inclusive passes. A student just unobtrusively hands you the pass and...voilå! Instant classroom management cred with your students, colleagues, and administrators!
These come six to a sheet. I cut them in half and every student gets three per semester. Print on colored paper for easy identification. Students with leftover passes at the end of the semester get extra credit, a forgiven assignment, or ??? - your call.
Warning Tip: In the case of an "emergency" no one is going to be very understanding if you're totally inflexible about things.
