[Homeschool High School Math]

Openstax has free textbooks for various college courses.

Their Elementary Algebra text covers a standard Algebra 1 course, and the Intermediate Algebra course Algebra 2.  There's also Prealgebra, Algebra and Trig, College Algebra, Pre-Calc and 3 semesters worth of Calculus to round it off.  Only drawback - the are no answer keys; you need a school email address for Instructor access to those.

There's also a High School Section with AP courses: History, Physics,  Micro/Macro Econ, and Stats.

[Who thinks the new editions BJU Math look really slick?]

Has anybody looked at the new edition math books from BJU?  From Grade 6 to PreAlgebra the books have a much cleaner look to them.  There seems to be more white space on the page, and there isn't so much 'clutter'.  I really like them.
