Bucket Filling it is based off of Carol McCloud's Have You Filled A Bucket Today? book. McCloud has authored 5 books in total about Bucket Filling and Tom Rath has also written a book entitled How Full is Your Bucket? For Kids that I share with students in groups as well. It has been around about 20 years but Lisa Hansen, an elementary counselor, published a curriculum of 10 lessons with reproducible activities through youthlight.com in 2015. I have used activities from The Bucket Squad in small groups but they also support the themes of self-esteem, kindness, empathy, and compassion that could be used for a grade level or school-wide if teachers buy in. A nice feature of the curriculum is a weekly parent/teacher update and tips for each session.
