The explosive ninth book in the Left Behind series will carry the world to the brink of Armageddon. A year of Algebra on Videotape is broken down into three phases, each phase being available separately. Phase two continues the basics. Phase three teaches advanced topics. If you have a slow learner, phases one and two could count as a year's credit in Algebra 1.
Prices vary accordingly.
I reviewed Algebra 1, phase one, good quality, and am very impressed. I love the fact that the worksheets are in Firebaugh's handwriting - the same handwriting he uses in his video lectures. And then there is the teacher himself. His coverage of Algebra is so thorough that I saw things I don't even remember learning in my college Algebra courses. He also provides solutions with the answer keys so that if you do have trouble working an equation you will have help figuring out where you took the wrong turn.
