I have three always homeschooled boys (entering 7th, 9th, and 11th grades). I feel like I've let them down in the math department. I can do lots of math, but my oldest has no interest in learning from me. My middle really likes Khan Academy, but got stuck despite spending adequate time last year working on Algebra I topics. He also doesn't like to work with me on math. My youngest could be good at math, but isn't particularly motivated. He's not doing high school math yet, but I might have a chance to get him on track before 9th grade. I can't picture any of them learning from just a textbook.
So what is working for high school math at your house with your kids?
