John Harold Saxon Jr. (1923-1996)was an American mathematics educator who authored or co-authored and self-published a series of textbooks, collectively using an incremental teaching style which became known as Saxon math.
I read/studied this book more than 30 years ago. It was an excellent review of the math I learned in high school. Now that I am retired I am going through it once again to prepare me for the Algebra 2 text (which I have).
My goal is to finish Algebra 1 & 2 in the next six months and then move onto the Saxon Advanced Mathematics text. My first major math goal is to get through the equivalent of Calculus 3, and move on to some introductory physics after that.
The Saxon series suits me well. It has more than 130 lessons with about 30 practice problems in each lesson. Every four lessons has a twenty problems test to evaluate your progress. Well designed program.
Suits some well, others not as well. Boilerplate for algebra when you don't have anything better to use. For the diligent or those who enjoy math the many problems will be helpful, for the rest they are intimidating. Very narrative-based, so in some ways good for those who want their math explained to them in words. Spiral method is supposed to keep you sharp on past skills.
As an homeschooler, I am doing the Saxon series. Most of my brothers also went through this series, so it's nice to find little comments or doodles in my books from them when they were around my age.
