You can download the free PDF planner for this American Girl Kirsten Lesson Plan for an American Girl Unit Study. This American Girl Lesson Plan Calendar is three weeks long, with an optional fourth week. All of the details for this free calendar are on the free American Girl Teacher’s Guide. I designed this unit and did these activities with my kids. We had so much fun doing this unit, so I am sharing it! It was perfect as part of a “gap year” in between our regular curriculum.
