I use these rewards for band and orchestra members. When an instrument goes home at the end of the day, I leave this note in their cubby randomly. They never know when I will reward them taking their instrument home! I also use these for clean cubbies to avoid crumbled up papers and trash accumulating. Again, they never know when the "cubby fairy" comes. I leave these notes with a small reward (candy, raffle ticket, etc.) and it gets tons of positive reactions!
