I am sure you can. When I was in high school, one member of the scout team would get one each week. Sort of a "Scout Team Player of the Week." I really liked this as a lot of people fail to realize the importance of a good scout team to help prepare the team every week. I really like the idea of classroom stickers as well.
@GreatestStory When I played we loved the incentive stickers. I would imagine most kids still do these days. As "childish" as it may seem, if done right it is a great way to recognize these kids accomplishments for going out there each and every day and working their asses off to give us a little entertainment on Saturdays (or Tuesdays)
