In my classroom, we talk about living a life of "purpose" - each one unique and specialized to the individual, based on a team building unit we complete at the beginning of the year. To review and refresh when we come back from winter break, we talk about the following quote from T.A. Barron "Every piece of the universe, even the tiniest little snow crystal, matters somehow. I have a place in the pattern, and so do you." Students then write about what they feel their purpose is right now as a fourth grader, and what they would like to see it become in the future!
