Darnelle, We are definitely soul sisters here! I find that everyone reaches that point in math when they can't teach it anymore, you know? The more I think about it, the more value I find in the fact that the kids TAUGHT THEMSELVES. Because in college, that's what it's all about, so it really made them MORE prepared. Our weakness is really a strength!
I do recommend DIVE CDs, but now there are even more choices for video programs as well. But we used DIVE very successfully.
Just wanted to say that I've had the same experience as you with the Saxon/DIVE Calculus situation. I've never had calculus, so definitely was not able to teach it. But after so many years in Saxon Math, my boys moved right in to calculus using DIVE and did extremely well. My oldest took calculus in his first semester of college and made a 98% 'A' in the class. All without Mom knowing how to teach it. (Had to laugh at what you said about when the boys would show you their work! My 11th grade son still does that with his calculus - I nod and smile and say "you're a genius!")
I'm not sure if you promote certain home school products, but if you do, DIVE is definitely a winner. I have lots of friends who love me lots just because I introduced them to DIVE!
Thanks for what you do. Not enough people know that they actually CAN home school through high school. Personally, I couldn't do it any other way.
