Do I understand this stamp page correctly? It's a list of homework with grades showing it was complete with all work expected done, turned in, and graded? (stamped in some way?) That you are an A student but here received a B that just went to a D because of this stamped page that's missing? Indeed, yes, tell your parents. Perhaps one of them saw it and doesn't understand it's importance. Someone could've placed it somewhere and forgotten to tell you. Or think of some place it could be that you've missed. I would appreciate my child involving me so I could help him.
The teacher had seen this sheet recorded all along until now? The point I'm making here is that the work had all been done and graded with the exception of this one page that isn't about subject matter(English ) but a matter or responsibility that's been lost. That's a pretty hefty penalty for something that's not subject related. Not a true evaluation of your knowledge of the material scored.
Did the teacher also keep track in a grade book what the true average is? Keep track that assignments were turned in? Because this is teacher responsibility in the long run. He/she should have an accurate record of grades. For what purpose is this record worth 200 points? Enough to lower a B grade to a D. I'm questioning the fairness of this. This isn't about a missing assignment, homework not done nor a test failed or a real final grade for this subject. Therefore not an accurate accounting of the true grade earned; unreflective of what was learned. Simply a missing page that has no reflection on what was learned/done. Am I understanding this correctly? while I can understand attaching points to such a requirement that seems pretty hefty to lower your grade that much.
It's possible your parent's could argue this case. You aren't in the habit of being neglectful. You are an A student. Your character and past record speak to that. Your grades have been excellent. Could an exception be made or some makeup activity assigned to overcome this grade? You have grades that could earn a scholarship if we're here longer than we expect. I hate to see this ruin your future opportunities and bring your grade average down. You don't know without asking. It could be you need your parents help to intervene and speak to the teacher to see if there's anything that can be worked out to change this grade. Sometimes it's only necessary to approach a teacher to work out a compromise. Your parents add a bit of weight to asking for this assistance. When a teacher sees parents and student working together to work out a solution it can make a huge difference in how they see the issue. They're more willing to make compromises.
FW is right. With the right approach most teachers are willing to compromise a bit in the right circumstances.
Let us know how this all works out. In the meantime I'll pray you find this paper. No one would've taken it from you would they? You seemed to have "just seen it in your backpack and that fast it's gone".
