Start with the books. Michael Waski has three books which will be available this Fall 2019. They are Montessori Algebra for the Younger Adolescent (Vol 1), Montessori Algebra for the Older Adolescent (Vol 2), and Montessori Geometry for the Adolescent. Next, move to the Review Sets. Skill Review Sets are thousands of unique math problems, with exams and answer keys, which are a perfect supplement to the books. Finally, keep an eye out for workshops & webinars which help you maximize your progress with the books and review sets!
