As instructors, we all know how haggard most students look on the day that a paper is due—the sunken cheeks, the bleary eyes, the undaunted yawns all signal to me that heady material isn’t going to be as quickly (or as enthusiastically) received as usual. So, many of us make it a point to have some sort of fun activity on the day that a paper is due. We all know the kind of activity I’m talking about—the kind where students don’t have to have read or prepare prior to coming to class.
