I teach in a small private Christian school, but this book is an excellent book to use in any setting, especially if you are planning lessons around other texts (both fiction and nonfiction) related to World War II, the Holocaust, or the post-WWII era. I teach both seventh grade language arts and world history, so I have the privilege of incorporating this book with my history unit on WWII and post-WWII. If you do not have this luxury because of departmentalization in a middle school setting, I would highly recommend that you get together with the history teacher(s) and try to plan together. If not, there are still plenty of activities to do in a language-arts-only classroom.
This unit includes higher-level questions for each chapter (can be for oral class discussion, written response, or even homework assignments), writing assignments, map activities, research/project ideas to meet different learning styles, a variety of cross-curricular activities, ideas for differentiation, and a supplemental book list.
