Founded in 1920, The National Council of Teachers of Mathematics has served as the public voice of mathematics education for more than 100 years, supporting teachers to ensure equitable mathematics learning of the highest quality for each and every student through vision, leadership, professional

everyone sees the value, beauty, and joy of mathematics and is empowered by the opportunities mathematics affords. For additional information about NCTM and the Services it provides, please see the
