While learning about communities, students will write a letter to someone of their choosing to learn what life was like for them as a kid in the community they grew up in. Students are able to identify similarities and differences between their life and the person they wrote to.
When I have used this in my classroom, students have loved hearing about other people's lives. After sharing the letters with the class, I have had the students create venn diagrams comparing themselves to the person they wrote to.
Make sure you have a back up plan for students who do not get a letter back. In the past, I have had family members write letters for me to give out or paired kids with someone who did receive a letter.
I hope your students enjoy this project.
