This memoir bundle is something I used for the last week of school. It would also work as a start of school writing piece to get to know your students.
You can use this packet for students to write their own 1-2 page memoirs (your kids will write more than that). There are worksheets for generating a topic, brainstorming and expanding the chosen topic, peer and self editing and revising the memoir, and gallery walk share out (read 3 other memoirs and write comments).
If you wish to extend it another week, in my intro letter (included), I explained which 3 memoirs we read before we began writing. They're three popular memoirs that you can likely find free online.
