The unit study in Book 5 is on The United States. First, it covers the fundamental principles for which the United States stands, then shows the westward growth of the nation. The book is simple enough for a young child to do independently, or a teacher or parent may present the lessons. Each drawing lesson includes a colorful picture and step-by-step instructions, while the writing lesson includes four simple handwritten sentences. The teacher or parent may introduce letter formation or have the children copy the sentences for handwriting practice, or use lessons as springboards for creative writing or report writing. Developed by an elementary school teacher and co-authored by her daughter. A brief list of the 21 lessons in the book includes The Pledge of Allegiance, Lincoln, Statue of Liberty, Capitol, Lewis and Clark, log cabin, The Alamo, map of the United States, flat boat, train, Model T.
