I used this writing activity in 2 different ways:
The first way was during a making connections activity. I read the story "I Broke My Trunk" (A Elephant and Piggie Book) by Mo Willems. Students made a connection to the story by drawing and writing about a time when they got hurt.
The second way was during Earth Day. We discussed how the earth is hurting and the students drew a picture and wrote a sentence about a way that they could "heal" the earth.
Hope you can incorporate this activity in one of your lessons. Enjoy :)
