I'm a long-term sub and have been accused by a student of losing her work. I'm sure that I didn't because I keep ungraded work paper-clipped together according to class and then immediately put it into another stack to be passed back once it's graded and in the book. I'm very organised when it comes to this, so I know I didn't lose it. I'm wondering if this is an excuse many teachers hear or if I'm only hearing it because she thinks she can get over on the long-term sub easily. Anyways, I told her that to have the grade put into the grade book she either has to show me the original paper with the grade on it or complete it and hand it in if she doesn't have the original paper . Am I being fair here?
