We homeschool our son and after a lot of trouble with an online course that used Saxon math, we landed on Math Academy. I found it much easier to use than Khan both for the parent and student. I do sometimes wish there was video content and discussion of application. But my son does it first thing every weekday and really seems to do good with it. Also worth noting it is accredited and lets you print a transcript.
