Saxon math, developed by John Saxon, is a teaching method for incremental learning of mathematics. It involves teaching a new mathematical concept every day and constant review of old concepts. In all books before Algebra 1/2 (the equivalent of a Pre-Algebra book), the book is designed for the student to complete assorted mental math problems, learn a new mathmatical concept, practice problems relating to that lesson, and solve a varied number of problems which are similar to the practice problems learned in that lesson and select previous lessons- all for one day's math.
