RightStart Mathematics is a comprehensive math program for children that is easy to teach and provides the foundation for everyday life, for advanced math, and for science in our technological world. The research-based elementary and intermediate RightStart Mathematics program is easy to use: the lessons tell you what to teach, and how and why, day by day and year by year. This unique program uses visualization of quantities, de-emphasizes counting, and provides visual strategies (mental pictures) for memorizing the facts. Understanding is emphasized. Math needs to be taught so 95 percent is understood and only 5 percent memorized. When children don't understand, they memorize until the burden becomes too great and then they give up. When children understand, they need less time in review and practice. In Levels A-E, the primary learning tool is the AL Abacus, a special kinesthetic and visualizable two-sided abacus; practice is provided with math card games.
