Great question, Cindy. The books listed on the curriculum guide are only suggestions. Use them as is best for your child and family. If your child loves to read, he or she might get through all of the books suggested. However, if you want to choose only a few so as not to overwhelm, feel free. Also keep in mind that some of those books we read only portions of.
Here’s a little “insider information”: As I write the handbooks that go with each history module, I will update the book list on the curriculum guide’s history modules to mirror only the books that are actually included in the handbook’s daily lesson plans. The other books will, of course, stay in our CM Bookfinder as great alternates or supplements, but the history modules’ lists will be fine tuned as we go along.
(BTW, everybody, I just finished the Joshua through Malachi & Ancient Greece module’s handbook. It’s at the printer’s right now.)
