My 8th grade son has received points off his school behavior card for being "off task" during his math class. While his teacher agrees he got points taken away for minor infractions, she says she is trying to prepare her students for high school. In the past I've taken screen time away for the weekend (he's only allowed to play his video games on the weekends which he loves). Once for a fairly substantial issue I took away screen time for a month. He told me today that disciplining him hasn't really changed his behavior at school which is obviously true. I'm not sure what else to do to get him to keep quiet during this class. If he gets any more points off, the school won't let him go on the 8th grade trip to DC. I told him today he would be embarrassed to have to tell his friends he can't go because he got detention but he said they would understand. Any ideas on what I can do?
