T he National Council of Teachers of

Mathematics (NCTM) leads. We lead in

setting—and meeting—high standards for

the teaching and learning of mathematics. We lead

improve teaching. We lead in getting results. That’s

how and why we work.

When you join NCTM, you gain access to all our

expertise, tips, lessons, research, connections, and

insights. And with all that, you get results—in the

classroom and in your career.

Membership matters to your students…

If you oversee the teaching of mathematics—whether

in the classroom or in the office—no one benefits

more from your professional development than your

students. The insight you gain and

apply affects what they do in the

classroom today and their success

with mathematics for years

to come.
