We have the kids on a couple different curriculums depending on what they’re studying. Like the younger kids we have them on a mix of Abeka and Sonlight studies and the older kids get David Barton’s Wall Builders studies for history. We also let each of them have an elective course of study like animal husbandry, mechanical engineering, geology, and etc.
They get about five to six hours of study five days a week (more if it’s snowing).
So far we’ve sent one to Hillsdale College so we must be doing something right.
We used Saxon math but Abeka for everything else. Daughter hated math but Saxon made it easier as their explanations were clear and built slowly on each idea. It would introduce a formula, work on it for 2 or 3 lessons then add another layer for 2 or 3 more lessons.
