One of our regular homeschooling patrons just alerted me that a new 10th anniversary edition of The Well-Trained Mind by Susan Wise Bauer and Jessie Wise was published in past May (ISBN: 9780393067088). This 814 page book explains the philosophy behind a Classical curriculum and provides a year-by-year outline on how to implement it. It’s a must-have for most collections. There are quite a number of homeschoolers using a Classical curriculum and even more who use some of it or are influenced by it.
This same patron also told me that there are audiobook versions of Susan Wise Bauer’s 4-volume The Story of the World series, a chronological history that takes readers (or, in this case, listeners) from ancient times through the present. If you can afford them, the books will be well-used in most collections, and I think the audiobooks will be a fine investment as well, something even some non-homeschooling families will find interesting.
