Further Up and Further In is a literature-based unit using The Chronicles of Narnia by C.S. Lewis. In addition to the textbook, you will need a copy of all seven of the Narnia books. Lesson plans cover Bible, character education, history, science, art, music, cooking, critical thinking, and writing topics. Each unit is based on one book in the Narnia series. Some additional resources are used, such as other books by C.S. Lewis, other reading books, and videos. Grammar, math, and spelling should be done separately. An introduction explains how to use the book.
