I purchased the Great Courses video set for Chemistry and several books for my ds. Barb Harmony’s site is where I borrowed all the ideas from (someone here posted a link to her site). I’m using her plans as a guide for me and *might* find him a class to attend but not sure about that yet.
I’ve only used one book in the Life of Fred series so I can’t comment on that.
For grammar, my ds used Our Mother Tongue this year (he’s in 10th). I do not plan for him to use any other grammar program in the next two years. He will have his notes from this book as a guide, plus, we have several books on grammar/parts of speech he can use as reference tools. He will be adding a foreign language to his subjects (probably Spanish) and he does a Latin program, as well, which I think is enough at this stage.
