Since retiring from homeschooling I have worked as a math tutor. I have passed all teacher certification exams required to teach high school math in Florida. As I help students with high school math I write out my explanations and add illustrations so I can help the next student more efficiently. Over the years these explanations have grown into a book that is about 150 pages long. Maybe someone can use it - it is free if you want it. This e-book contains the explanations and examples I use as I tutor, but no practice problems. You would have to use it along with a textbook or other curriculum. E-books are very easy to update. For example, if you find the color coding annoying I can give you a black and white version. If you have any comments on the book please post them in this thread.
