I mostly ignored them. When the schools tried to send home worksheets I counseled my kids, "Do a few problems until you're sure you know what they're trying to teach. Then stop." I resented the school infringing on our family time. The grades were not exactly annoying so much as useless. The teacher was supposed to know the kid and know where their strengths and weaknesses were, address them. Producing a letter grade from a pile of paper was only what, 2 bits? of information about my kid. Student-teacher conferences could be good. If they remembered my kid at all, and knew anything about how they were doing in their class. If they opened their grade book during the conference, I would close it and get their attention back, say "Tell me about my child's behavior in your class." Honestly, letter grades are no better than a scarlet letter to hang around the kid's neck.
