The skittles are used as a classroom management tool. I give out skittles when our room is cleaned up quickly, everyone is sitting on the carpet correctly, we made good choices at lunch, etc. I don't give them out EVERYTIME something is done correctly, just randomly. Sometimes everyone in the class will get one, and sometimes it's only the students making the right choices. I usually only give out skittles once or twice a day.
The other candy I give out is Hershey's kisses. If you've never heard Dr. Jean's Kiss Your Brain song, it's a hoot. My preschoolers think it is the funniest song. They beg to hear it every morning. The song encourages kids to kiss your brain (kiss your fingers then touch your brain) when they do something smart. I use the Hershey's kisses as an academic reward. When we are doing assessments I will give them out. I will also give them out when I can tell students are paying attention and putting a lot of thought in to their answers/statements.
I used some Dollar Tree containers and a couple packages of stickers (from Hobby Lobby) to make my reward jars this year. I'm really pleased with how they turned out. These will look great on my teacher shelf in my classroom.
Hope your enjoying the last little bit of summer!
