This is the third week that we've used these buttons for peer compliments. Every Friday, students select one another to receive each button until they have all been rewarded. I do not limit the number of buttons a single student may receive, as long as they do not receive duplicate awards with the same word. I do not sway the choices, but I do look out for people who play favorites.
Students wear the buttons all morning - where they are seen by others in the halls, in the cafeteria, and during one recess.
