About Us

The UNITED STATES MENTAL MATH FEDERATION (USMMF) is a not-for-profit organization and was founded in 2006. Mental math education, especially the Abacus Mental Math, is rapidly picking up the focus for education in early childhood around the world. The membership spans every state and territory of the U.S. and beyond. There are more than 10,000 abacus mental math tutoring centers in the world but only less than 100 in the United States. The difference indicates a strong demand of the mental math education in this country in the near future, if not current.

The USMMF conducts and sponsors the Speedy Math Competition which is a once a year event encouraging youngsters to be active in mental math. USMMF also work with mental math associations around the world in coordinating international events. As a not-for-profit membership organization, the USMMF applies its revenue to services and programs benefiting its members and mental math in America.
