National Council of Teachers of Mathematics (NCTM) is the world’s largest mathematics education organization, with 80,000 members. OCTM is an NCTM Affiliate.  {Other regional affilliates: Washington State Mathematics Council, Puget Sound Council of Teachers of Mathematics, British Columbia Association of Mathematics Teachers}

NCTM Illuminations has resources for teaching and learning mathematics for grades pre-K—12, including lessons and interactive tools searchable by NCTM’s Principles and Standards and by the Common Core State Standards.

Principles to Actions, NCTM’s landmark publication, describes specific, research-based teaching practices and core principals that are essential for a high-quality mathematics education for all students.

NCTM Classroom Resources, which became part of NCTM in 2015, provides resources, materials, activities, person-to-person interactions, and educational products and services to support K-12 math education. 

The National Council of Supervisors of Mathematics (NCSM) is a mathematics leadership organization for educational leaders that provides professional learning opportunities necessary to support and sustain improved student achievement.
