Writing a "thank you" letter is an excellent way for young children to practice gratitude. A 2014 study found that writing a gratitude letter contributed to young children's (7-11) awareness of positive social exchanges, increased their gratefulness, and improved well-being.
In the Gratitude Letter worksheet, children are provided a template for writing a letter to someone for whom they are thankful. Children are asked to list why they are grateful, what makes the person special to them, and other questions to help bring forward positive memories.References: Froh, J.
