Natural Math, LLC, founded 2001, places the maker approach at the center of its mathematics education philosophy. The organization's motto is "Make math your own, to make your own math." Physical and virtual modeling opens rich and brave math adventures. For example, families with toddlers do projects on symmetry and tessellations, four-year-olds design function machines, and six-year-olds build models of infinity, fractals, and limits. Natural Math has more than a decade of proven track record in curriculum and experience design, in grant-supported and commercial R&D, in national and international leadership among Math Circles, and in building online communities for mathematical education.
