The Math Forum is a leading center for mathematics and mathematics education on the Internet. The Math Forum's mission is to provide resources, materials, activities, person-to-person interactions, and educational products and services that enrich and support teaching and learning in an increasingly technological world.

Our online community includes teachers, students, researchers, parents, educators, and citizens at all levels who have an interest in math and math education.

The Secondary School Teachers Program (SSTP) is structured around three goals: all teachers should continue to professionalize their work by
        continuing to learn and do mathematics
        analyzing and refining classroom practice
        becoming resources to colleagues and the profession
The SSTP is organized around three strands related to these goals and is enriched by additional activities tailored to specific participant needs and by programs involving other components of the PCMI community.
