I reward students' good behavior and leadership skills with leadership dollars. I print them on gold paper and cut them in advance. Then, every grading period I allow kids to bring their dollars to class and buy prizes from my fun box. I also give out dollars to those who have received no notes home and/or no warnings the entire grading period. It rewards them for their hard work and teaches them to be responsible and keep track of their "money". It is a very effective way to make sure all the quiet students who don't seem to get as much attention know that they are recognized and appreciated.
