Algebra is generalized arithmetic, so basic math skills are reviewed and built upon throughout the course.
Saxon math is used in the study of Algebra I and II. The Saxon approach uses incremental development and continual review. The incremental development is the introduction of topics in easily understandable pieces (increments), permitting the assimilation of one facet of a concept before the next facet is introduced. Both facets are then practiced together until another is introduced.
Since Algebra I is the critical course for developing skills used in advanced math and science and for developing thinking skills used in modern technological society, this course involves rigorous practice.
