Ds1 is in yr 5. He works really hard at school and is doing very well. He has 2 part time teachers - both seem very nice & approachable. However since half term ds1 has become very aggressive at home, especially with his younger brother. He seems really angry and flies off the handle at the slightest problem.
Eventually got out from him that one of the teachers is punishing the whole class because a handful of children are chatting during work time. This is really upsetting ds1. He is keeping them in for "half of break time" - probably not that long, but seems it to ds1. He is not one of the chatters and feels wrongly punished. I know this is a common form of punishment - ds2 has it sometimes at his school. Ds1 loves play time and runs around playing football - runs off the excess energy.
Should I speak to the school? Anyone else have this problem?
