Our vision is to create a world where all learners know, use, and enjoy mathematics through curriculum, professional learning and community.

– IM Team

Our Purpose

Founded in 2011 at the University of Arizona, Illustrative Mathematics is guided and inspired by educators who work in spirited teams to do extraordinary things.

The result is a comprehensive suite of math curricula, designed to encourage engaging mathematical discussion, supported by tasks, lesson plans, professional learning, and community.

IM 6–8 Math™ v. III and IM 9–12 Math™ v. I certified by Illustrative Mathematics are available as open educational resources (OER) and free to access by anyone. IM K–5 Math will be available in 2021. To be assured that you are accessing the most current versions authored by IM, we created an IM Certified designation that highlights the organizations with whom we have an ongoing partnership. Additionally, the aligned professional learning certified by Illustrative Mathematics is designed to be interactive and engaging to ensure the immersive experience and best practices needed to seamlessly implement the curricula in your classrooms.

First partnership leads to continued growth.

Open Up Resources 6–8 Math 2.0 was authored by Illustrative Mathematics. Illustrative Mathematics, authored, reviewed and approved all of the content contained in Open Up Resources 6-8 Math 2.0. OUR 6–8 Math 2.0 is a high-quality curriculum, and Illustrative Mathematics is proud of its collaboration with Open Up Resources, which brought one of the first full-course OER middle school math curriculum to students and teachers across the country. Please contact OUR for more information about their version of an IM-authored curriculum.

Our mission is to create a world where learners know, use, and enjoy mathematics through curriculum development, professional learning, and administrative guidance.

We collaborate with and provide guidance to states, districts, curriculum writers, and assessment writers to help improve mathematics education.
