For young readers, a wonderful Enslow book that imaginatively addresses these issues is Molly the Great Repsects the Flag: A Book About Being A Good Citizen. Author Shelley Marshall's 24-page title provides a character driven narrative from which larger notions of citizenship emerge. The book’s Guided Reading Level "F" and lovely, watercolor-style illustrations invite readers to enjoy each page and absorb its message about civic responsibility. Molly the Great Respects the Flag also comes with a free, downloadable teacher’s guide, including curricular-based activities and a useful reproducible piece.
The book, included in Enslow’s "Character Education with Super Ben and Molly the Great" series, is available in paperback for $6.95. The title is also available in a library-bound version.
