Ray’s Arithmetic teaches arithmetic in an orderly fashion, starting with basic mathematical rules and principles and building upon those rules as students progress in their studies. Ray’s Arithmetic utilizes two of the most valuable mathematical teaching tools which have been virtually erased from modern education — story problems and oral math. Oral math was a common practice in the 19th and early 20th century and helped develop the minds of innovators like Henry Ford and Thomas Edison. For centuries, Ray’s Arithmetic has equipped students with the foundational tools needed to conquer any form of mathematics with relative ease. Now you can offer your students that same advantage.
