Illustrative Mathematics® Adds BetterLesson to IM Certified® Partner Network, Bringing Personalized Coaching to IM® Math v.360 Classrooms

September 3, 2025 — Illustrative Mathematics (IM) today announced that BetterLesson has joined the IM Certified® partner network, adding personalized, hands-on coaching to support K–12 districts implementing IM Math v.360.

Successful implementation isn’t just about choosing the right curriculum. It’s about empowering teachers, building consistent routines, and fostering lasting confidence in the classroom. That’s where BetterLesson excels. With a proven track record of supporting over 86,000 educators and nearly 4 million students, BetterLesson brings deep expertise in personalized coaching and professional learning. 

“A great curriculum is just the beginning—it’s the partnership, planning, and support that bring it to life,” said Kristin Umland, CEO and cofounder of Illustrative Mathematics. “IM has great professional development, but we do not offer coaching, and we are excited to welcome BetterLesson as a certified coaching partner. We can’t wait to see how schools thrive with this added layer of support, which so many have said is essential for helping teachers implement problem-based instruction effectively.”

As an IM Certified partner, BetterLesson will work closely with IM to provide role-aligned coaching and professional-development services at every stage of implementation, from initial planning through classroom refinement.

“We've spent over a decade helping K–12 educators implement student-centered practices that drive real results,” said BetterLesson CEO Matthew Kennard. “High-quality curricula like IM Math v.360 deserve equally high-quality implementation support. When districts invest in personalized coaching alongside curriculum adoption, they’re ensuring their teachers have the confidence and skills to bring problem-based learning to life in every classroom—and that’s where sustainable change happens.”
