This lesson is based on the book Have You Filled a Bucket Today? A Guide to Daily Happiness for Kids by Carol McCloud (Ferne Press, 2006). The book’s message is that we fill each other’s invisible buckets when we show respect and kindness and when we are unkind to others we dip in their bucket and it empties our own. Our happiness increases when we treat others well. Students identify and discuss examples of “bucket filling” and “bucket dipping” from their own lives.
