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.
As one of my left-overbooks from high school, found this book generally helpful for relearning/refreshing the concepts again. However, the layout of the text being incremental and integrated is a less than ideal reference book (compared to texts that group similar lessons sequentially in blocks or units). This is only because the sheer amount of content (algebra, geometry, precalculus, examples. etc.) makes it difficulty to identify foundational areas and progression quickly, save for "cover-to-cover" reading. I still stand by my thoughts the quality of the content learned is very good with rigor.
The text is made for progressing through lessons sequentially, but students may find certain lessons difficult to understand. A knowledgeable teacher, tutor, or reference material is a blessing to clarify some concepts on select lessons, as some areas are not as intuitively explained as the rest of the text (or can result in confusion). The problem sets are preceded by practice problems (typically two or so depending on the material addressed), and has 30 additional problems per lesson. Although the answer section of this book offers a final solution for every odd answer, it is noteworthy they did not offer both for the practice problems in this text (although, it is found in the teacher's answer book).
Would recommend despite the frustration with the math subjects I had as a student, as it helps students delve into advanced topics. From a student perspective, I encourage educators to considering limiting the number of problems assigned to their students from each set, as doing all questions in the later problem sets as the units increase in complexity and can be overwhelming. Otherwise, more time and frustration is spent trying to complete and "get through" every problem opposed to understanding concepts, formulas, and methods more clearly.
I went through this book to be able to help my daughter, if needed, as she began working through it. I am not a great mathematician. 😊 I have worked through Saxon (3rd ed.) Pre-Algebra, Algebra 1, and now Algebra 2, and am convinced that it is the best math program. It uses the spiral approach, which allows for mastery of the concepts through incremental teaching and repetition of those concepts in the daily work.
We watched the YouTube videos that Scott Clifton has posted, teaching each lesson. We also relied on the Saxon Teacher videos on vitalsource.com. They offer a yearly subscription to the videos for around $35.
Is your child struggling with math that seems confusing and convoluted to you? Start this series at whatever point he or she needs help, and stick with it. Just do all the problems. You WILL solve your child's math problem. I did it with my own children, and have recommended these books to many others. THEY WORK.
