I use this cute sign on a bucket that I hang above the doorway to my classroom. It reminds my students each day to be a "Bucket Filler" to someone they know! You could also just print and hang the sign, but I have to say that the bright orange bucket is super adorable!
One the first day of school, after I read the story, we talked about ways we can be "Bucket Fillers" everyday. I then gave each student a couple of brightly colored paper stars and had them write specific actions and/or words they could use to be a "Bucket Filler" and then we filled the bucket with those ideas! The kids LOVED the story and activity and it has really fostered kind, loving behavior amongst the children already!
