Several parents have mentioned using the Oak Meadow curriculum with their children. Here is a little blurb from their website:
"Oak Meadow was founded in 1975 by Bonnie and Lawrence Williams, and over the past 35 years, Oak Meadow has grown into a thriving organization serving families and schools around the world. The founding philosophy has remained strong throughout our years of growth and today our courses set the standard for a creative, meaningful home-based education.
We believe that homeschooling can play a significant role in creating a better world by helping children become strong, creative, independent human beings. We are honored to be a part of the thriving homeschooling movement and to have been involved in the education of so many students. A desire to support families in their choice to homeschool is behind everything we do!"
I took a look at their curriculum and decided it was worth the money to purchase several of their grade level resources. You can purchase the full curriculum, just the individual components or you can enroll in their school. At this point, I don't feel the need to enroll in a school but I may as the children move into middle school years. There is an online version as well.
From what I can tell, the school aligns with our beliefs as UU's. I actually lucked out and found two of the books used. I will update once I have the books in hand.
