What Is a MathRack

The original arithmetic rack, also known as a Rekenrek, was developed by Adrian Treffers, a mathematic curriculum researcher, at the Freudenthal Institute in Holland. It was designed to support the natural mathematical development of children’s addition and subtraction strategies as well as encourage and enhance children’s strategic mathematical thinking.

Helping Your Child be Successful

Mathematics education in the schools today often looks quite different to parents than what they remember from their past schooling. Emphasis has shifted away from pencil/paper arithmetic and drill, to mental arithmetic and a deep understanding of number and operation as a foundation for algebra. As a result of new standards, children today are expected to write mathematical arguments, choose appropriate models, analyze patterns, and solve problems.
