As I stated multiple times, it's easier in elementary then secondary. I teach in an inner city school with kids absolutely dying for adult attention. I've never been accused of playing favorites with my approach. I have special stools in my classroom that move- all the kids want to sit on the them. Certain kids get to sit on the stools all day long every day. Other kids only get them as a rare reward. No resentment- AT ALL. Yes I can't control their emotions but I can talk to them and explain why things are the way they are.
