My DD will be in 7th this year. I’ve looked at the Apologia and it looks like too much for my oldest. I also love the idea of sticking with living books. Next year we’ll be continuing with 106 Days. I just ordered Natural Science Through the Seasons and we may be using Science Experiments You Can Eat if we have time. I think at some point we’ll have to switch to something more challenging for my oldest, but I’m holding off another year or two.
I read a blog post awhile back (it was probably something someone here posted) about how well someone’s DS did in college even though he hadn’t previously used text books. It inspired me to stick with the living books. I’d post it, but I don’t think I bookmarked the blog post. 🙁
I’m considering these books, but I haven’t heard much about them…they have several sets of books, some of which have suggested credits for high school. I have a couple of the Tiner books and they look really good. http://www.nlpg.com/homeschool/middle-school
