I wonder if making it impersonal might be a better start. I'm afraid my Citizenship hat comes to the fore and looking at having right to an education; a small case on a student misbehaving, who is affected, why does it matter, what should be done etc. then look at school rules and see if they are 'up to the job' of ensuring everyone has he right to an education. Plan B think about ways of moving the group round each time. Use a pack of playing cards everyone with a heart etc. everyone with a 2. I have done it with sweets, scrabble letters etc. Plan C come up with school rules for classroom; include rewards and sanctions.
