RightStart™ Mathematics is a complete math program that uses visualization of quantities, de-emphasizes counting, and provides strategies and games for learning the facts. The primary learning tool is the Cotter Abacus, a specially designed two-sided abacus that is both kinesthetic and visual. These beginning lessons will build a firm foundation with number sense through quantity recognition and visualization strategies using the AL Abacus. RS2 Level A helps the child understand quantities based around 5s and 10s. This level includes addition and subtraction to 10, place value to the hundreds, and some basic geometry and measurement. Money and clocks are introduced. Card games are included in the lessons. Problem solving is emphasized. This is typically equivalent to Kindergarten or First Grade math, but RightStart recommends taking this placement test to determine the best level for your child to begin. If your child shows an early interested in mathematics, they can start this curriculum as a toddler, or in preschool.
