RightStart Mathematics

RightStart teaches number sense with the Cotter Abacus, a two-sided abacus designed for the program, and trains children to see quantities in groups instead of counting them one by one. Card games do much of the work of learning and reviewing facts, which makes it a good match for a young child who balks at worksheets. It covers the elementary and middle-school years. The lessons are taught with the abacus and cards rather than handed over in a workbook, so expect to sit alongside your child for each one; the payoff is a child who understands why the arithmetic works, not just how to do it.
