Yes, you absolutely can use SOTW as a stand-alone program. But it can be so much more!! The AG is worth the maps alone - doing mapwork with every topic over the years builds an understanding of Geography that is naturally integrated with the history of those areas. I also appreciated her literature suggestions. Many families never get to the supplemental activities - but for us, they are key. They can be a lot to keep up with on your own, so I have chosen to turn SOTW into a class with other homeschooling families - it ensures that I follow through and actually make it happen. I have found that the hands-on experiences become an excellent memory aid. Years later we still remember Fort Necessity, because we built it and acted out the battle! I remember the Gordian Knot & Alexander the Great because we learned how to tie trick knots, we chopped down a British Flagpole when we were learning about New Zealand, we burried a heart under a tree when we were learning about Livingstone... many of these activities were things that I came up with myself, but the Activity Guide was a good starting point. We also have a themed snack and learn more about the culture of these areas with song, dance, games, etc. Now that we are heading through the cycle again, we will incorporate a lot more supplemental reading, and integrate it into our writing program. History was never very interesting to me as a subject in PS, it is now my son's favorite subject and I am passionate about it too! I will admit that I am Type A about this program, and not everyone wants to put that much energy into it... but it can be so much fun and very rewarding. I think that the Activity Book is a great product for parents that want more enrichment but may not have the energy to come up with it all themselves.
