The CMA method consists of a three-step process to teach Abacus and Mental Maths.
CMA 3-Step Method
Unlike the one-hand method that mainly uses the Left Brain, the two-hand abacus method uses both the Right brain and the Left brain. The Right Brain is mainly associated with the Imagination while the Left Brain is mainly associated with Logic.
By stimulating both sides of the brain simultaneously, the CMA’s Abacus and Mental Math method encourages Total Brain Development.
