I've started giving out "Star Bucks" in my 8th grade class, and it's been working out great. The kids will be able to redeem the "Star Bucks" for candy/stickers/pencils etc, and my "Star Bucks" all have the Starbucks logo on it which makes me chuckle. Anyways, I have this really hardworking girl in my class, Hannah, who is still a little behind, and is coming in early for extra help. On Tuesday I gave her a "Star Buck" for answering a question most of the way right (because I really wanted to encourage her and give her one). After class, she comes up to my lectern, and in this really sad voice says "Mr. K, I didn't answer the question right," and then hands back the Star Buck. I try to refuse it, saying it was close enough, and she just says, "No, no" then puts the Star Buck on my lectern and walks back to her desk.
It was so cute and awesome. I'm sad she didn't keep it, but it was so nice to see that she really wanted to actually win one, and was honest enough to want to do it the right way.
