Hi There Sounds tough, and it is a situation that many teachers face; the needs of the few outweighing the needs of the many, and spoiling the class learning. That's a noble intention. But keeping them in with all the other kids is ruining- I say, ruining- the room for everyone. I feel this too. These kids, if they are persistently and aggressively playing Ker-Plunk with your lesson plan, need a new strategy. In an ideal world they would be assigned to a personal teacher. This world is far from ideal, so we make it make sense as much as possible. They lose their lunches and golden time- big deal, as you point out quite correctly. Some kids chew up lost lunchtimes like caramel. They need the next level; temporary exclusions, parking in other rooms, and provision external to the classroom. If you can't save them, then save as many as you can. Get the school/ line management involved in the solution, and definitely get meetings with the parents to let them know what will happen if no progress is made. But I get the feeling that these kids are enjoying the attention, and have quickly realised that mucking about will lead to....not very much, actually. Misbehaviour brings them power and attention, and that attention can exaggerate the behaviours in a hideous feedback mechanism.
