Another source of homeschooling materials other than Pathway publishers would be Rod and Staff. Rod and Staff is an AMish-Mennonite or Beachy Amish company that has very good school books. I taught for five years in a private Christian school and I introduced them to Rod and Staff English grammar. These are superlative grammar books and are lauded on most homeschool websites. They are also incredibly inexpensive, particularly when compared with other company's offerings. Rod and Staff has a full range of materials for grades 1-10 , but I believe they are extending it to 12th grade soon or perhaps already. I think their science books are terrific as well. I used the fifth and sixth grade curriculum and it included the text, a teacher's text, workbooks, and a test booklet. The cost of each was very reasonable, in fact the tests were about $1. They will send you a sample of curiculum for any specific grade you are interested in as well. I also have used Schoolaid books which are used both by Amish and Mennonites.  An O.O. Mennonite schoolteacher friend of mine wrote the health book which was well researched and very science based. Rod and Staff can be ordered directly from their business or online through sites like Anabaptistbookstore. com. Susan
