This "What's Your Story?" PowerPoint guides students through all the basics of memoirs (definitions, examples, characteristics), but then goes on to include a compare-contrast chart comparing the memoir and autobiography. The PPT, which could easily be used as a mini-lesson before jumping into reading a memoir, is also a nice introduction to the six-word memoir writing project.
The PPT also includes a short quiz and answer key! The PPT could also be printed for use in handout form.
