I volunteered abroad in rural Ethiopia and a village in a remote mountainous area of China. I plan to return to both places and teach for as long as I can make it work. I want to focus on STEM, but first I would like to reteach myself math and science from pre-school all the way to college-level math, such as Calculus, Physics, etc., so that I am confidently able to teach them. Almost none of them speak English, so I will be teaching them that as well along the way, since I can speak Amharic, Mandarin and Cantonese.
BUT I would like to teach them from a real-world approach where I am able to immediately show them the practical usefulness of what I'm teaching them. I've seen the website "Mathalicious" and it is inspiring. But I would like to get a set of textbooks that are widely used in academia to get them from a pre-school level of understanding of these subjects, where the only required prerequisite is to understand English, to the advanced levels. And I have also seen websites like Khan Academy but I would like something that is more official and mimics the curriculum progression flow that is standard in public/private school settings. Eventually, I hope to find a way to get at least a few children here somehow.
What I've found so far: http://www.doe.mass.edu/frameworks/
This website lists objectives and goals, but doesn't list any textbooks to follow.
This is the only state website I've seen so far that includes state-approved textbook materials that I can go through. It only lists Reading and math so far and the list is not really detailed at all though.
So, to be as specific as possible, I am searching for a list of good (text)books (based on your professional experience) that I can work through to arrive at advanced math and science.
Hopefully, I can get an answer like, "Follow this progression of books "xxx". Ask here if you need help figuring out how to apply it to the 'real world'."
