Saxon Math is another well-researched program which is popular in the United States for its incremental approach to Mathematics. It breaks down complex concepts into related increments, thus, giving students ample time to understand and practice the lesson. It distributes instruction, practice, and assessment throughout the lessons and school year which enables students to master concepts. In Saxon Math, as new lessons are introduced, previously learned concepts are likewise reviewed. This helps in ensuring that the child integrates and retains math concepts.
