I've used Teaching Textbooks (http://teachingtextbooks.com/ http://teachingtextbooks.com/) for math up to Precalculus. It's a self-paced, rather engaging math program with good word problems. For elementary school, their curriculum has a more interactive program with word problems, quizzes, etc. and in middle school and high school it becomes self-paced lectures with problem set / workbooks. Another good, similar program for high school is k12 which I've heard good things about too. There are some good / new curriculums out there for homeschoolers.
