RightStart Mathematics is a paid hybrid mathematics program for kindergarten through seventh grade, with Android, iOS, and web availability. It is designed for elementary and middle-school children to understand, apply, and enjoy mathematics. Lessons visualize quantities, reduce emphasis on counting, and use strategies and games for learning math facts. The main tool is the two-sided Cotter Abacus, which provides visual and kinesthetic learning and supports place value through thousands. Math card games supply practice and review while the program minimizes review worksheets and eliminates flash cards. Homeschool materials are organized by levels rather than grades, allowing students to begin at a recommended level and progress at their own pace. Lesson plans, parent guidance, and offline access are included. The maker also describes tutoring and classroom offerings, apps, and a placement test that requires no account. The Level A homeschool book bundle PDF is listed at $109.25, paid once.
