But just with the form tutor
Would it be appropriate to bring up concerns re the behaviour in the class with them or not?
There's one child in particular who seems to either single handedly disrupt the class or recruiting the others to muck about.
He spends half the lesson either pretending to go to the toilet or if he's refused he spends it asking to go to the toilet. He was amongst those responsible for preventing the class from finishing reading yesterday and while they were kept in to finish and miss half of lunch, guess who got to fuck off to the toilet 
The same name crops up on pretty much a daily basis. Dd just wants to get on with her work.
The only plus side is he is no longer sat next to my dd but I had to get him.removed from.next to her as he was bullying her. He may not be next to her throwing her stuff abkut and shoving her around but he's still stopping them all from.being able.to get on with things.
