I'm at my wits end with some of my students. On almost any assignment, test, or project I give at least 2 students forget to put their names on the paper. I've been subtracting 1 point from the assignment, hoping that would get the point across. However, it hasn't. So I told all my students that from now on if they turn in something without their name on it I'm going to throw it away and they will have to re-do the assignment at home and bring it back the very next day.
