To help my students improve on areas that they find difficult, I placed a "personal goal" sheet on each table, filling in their name and 2 goals to work on. These goals may be personal, social, academic or emotional. When I observe them working on their goal to improve themselves, I tick off one smiley face. They are rewarded when their sheet is complete and if necessary, given a new one.
These sheets can be printed and laminated for further use.
