What Illustrative Mathematics does
Illustrative Mathematics is a 501(c)(3) nonprofit organization founded in 2011 at the University of Arizona by mathematicians Bill McCallum and Kristin Umland, becoming an independent entity in 2013 and headquartered in Oro Valley, Arizona. It develops and distributes problem-based K-12 mathematics curricula under the IM v.360 umbrella, spanning IM TK Math (launching Fall 2026), IM K-5 Math, IM 6-8 Math (with an accelerated pathway), and IM 9-12 Math. Curriculum content is available free as Open Educational Resources via AccessIM.org and is also distributed commercially through three IM Certified partners—Kendall Hunt (print), Imagine Learning (enhanced digital), and Kiddom (AI-powered platform)—supplemented by a certified professional learning network and additional supplemental partners.
The business model blends freemium reach with licensing, royalties, and professional services revenue. The free OER channel under Creative Commons builds adoption and funnels districts into paid commercial versions sold by partners, while direct revenue is generated through IM Certified Professional Learning delivered by trained facilitators on-site or virtually, and through foundation grants from major philanthropies (Gates, Carnegie, Chan Zuckerberg Initiative, Heising-Simons, Hewlett, Kellogg). Reach metrics include approximately 3.6 million students, 89,000 teachers, 2,313 districts, and 44,700 professional learning attendees, with 39 states served in 2024-2025.
The technology stack centers on standards-aligned curriculum design, an AccessIM.org digital delivery platform, the IM Resource Hub, and integrated third-party AI capabilities through Snorkl, Kiddom, and Coteach AI partnerships. Distribution combines self-serve OER access with enterprise channel partner sales and direct professional learning delivery, supported by content marketing, social media, webinars, and conference presence. The organization has secured state-level adoptions including Utah's K-8 Recommended Primary designation and California framework alignment, and holds all-green EdReports ratings across all review gateways for IM v.360 K-12.
