Hi and welcome Roan! 🙂
First, I have to ask why are you thinking of making the change? Have you been dissatisfied with Sonlight? If you are happy with what you are using, I wouldn’t change. As the old saying goes, if it ain’t broke….
If you are really feeling a pull to a more CM philosophy, you can definitely use your favorite Sonlight books as part of your CM homeschool. Have you looked at the free curriculum guide here on SCM? It will walk you through what they recommend for all the subjects (except state history) and grades you mentioned above.
If I were you, and I were happy with many of the Sonlight choices, I would study Charlotte Mason’s philosophy more for myself, so that I could apply her principles and put together my own curriculum plan. In fact, that is exactly what I’ve done for most of my homeschooling years (minus the Sonlight part).
If you are the type who loves having everything planned our for you, then I would definitely go with the SCM guides to help you pull everything together.
Here’s what we are doing for my daughter’s CM high school social studies:
James Stobaugh’s history texts are our spines for American, World, and British history. Then I add in whatever living books I want to. My daughter reads one lesson from the text and 20 minutes from a living book 3 days a week.
We use SCM’s Visits To geography series along with reading from a living geography book once a week.
On the 5th day of the week, my daughter chooses an essay question from the Stobaugh books and writes an essay on it. She then reads from a living history book for 10 minutes.
We will add in Government and Economics at some point. We have already covered some of this using Uncle Eric books, a book on the election process, and videos from Prager University.
We aren’t required to do state history here in Florida but if we were, I would use living books for that as well.
I pull our living book choices from Simply Charlotte Mason, Ambleside Online, and many other resources.
Hope you find the perfect fit for your family! 🙂
