Last year one of my adorable first graders brought in a book to our class. Her mother wrote me a note saying that her daughter thought the book would be perfect for us! The idea is that when you help "fill up" peoples' buckets by being nice to them, they in turn will spread the love :).
We loved the book, but I didn't do a very good job following through with the ideas... needless to say it didn't really stick. This year when I started blogging I saw http://thefirstgradeparade.blogspot.com/2010/09/have-you-filled-bucket.html on First Grade Parade. I didn't have access to the same book, but I was able to get a hold of How Full is your Bucket? What I loved about this version is that it talked about how kids are sometimes mean not because they are bullies but because they are hurting inside.
So I created my own "bucket wall." So far my kids love it and it is really sticking. I actually assigned people to write to for now. I want to make sure all my kids feel loved! After I finished explaining the project, one of my little girls said "You mean you are letting us pass notes???"
