"Oops! I'm missing something" is a sheet used as part of having my students take responsibility for their actions. Students know that if they come to class without an assignment they grab an "Oops Form" and fill it out. They then show me the form and bring it home to have a parent sign. I keep these in each student's file. Repeat offenders are often shocked when I pull out a stack of papers to show them just how many assignments I have not received.
