CPM Mathematics
Problem-Based Math Curriculum for Grades 6–12
Research-backed math curriculum for grades 6–12, built by teachers and designed to develop deep mathematical understanding through collaboration and problem solving.
Why CPM
What Makes CPM Different
Every design decision in CPM curriculum comes back to one question: how do students best learn and retain mathematics? Here's what 35 years of classroom practice and a growing body of research taught us.
35+years of classroom practice and researchStudent-Centered Learning
Students work in collaborative study teams of 2–4, providing structured opportunities for mathematical discourse, risk-taking, and idea refinement. Teaching strategies are designed to make collaborative study teams genuinely effective, not just a seating arrangement.
Problem-Based Instruction
Every lesson is built around engaging, non-routine problems. Students construct knowledge through embedded questioning and productive struggle, arriving at mathematical understanding rather than having it handed to them.
Research-Supported Design
CPM's Three Pillars (Collaborative Learning, Problem-Based Learning, and Mixed Spaced Practice) are grounded in decades of mathematics education research and validated by the 2024 Research Base update. Built from the research up, not retrofitted to it.
Connected Knowledge
Topics don't exist in isolation in CPM. Concepts are interleaved across the course so students revisit and reinforce ideas over time. Mixed, spaced practice builds genuine long-term retention, not cramming before a test.
High-Quality Resources
CPM curriculum comes with a full ecosystem of support: embedded digital tools, access to homework answers, resources to keep families in the loop, and a variety of resources for teachers including access to CPM's extensive professional learning offerings.
Built on Evidence
CPM's Three Pillars of Research
Synthesized from NCTM standards and decades of constructivist research, CPM's Three Pillars (Collaborative Learning, Problem-Based Learning, and Mixed Spaced Practice) continue to be validated by current mathematics education scholarship. Read the full research base to understand the evidence behind every CPM lesson.
Everything You Need
High-Quality Resources Included
CPM curriculum comes with a full ecosystem of support tools for students, teachers, and families, built in, not bolted on.
eTools
Interactive digital tools for mathematical exploration (graphing, geometry, algebra tiles, and more), accessible on any device.
Improved Independent Practice
Practice problems designed to support mixed, spaced practice and balance content over time. For CC3e and IC, teachers can turn answers on or off. Available digitally or in print through the student consumable.
Family Support Resources
Collections of exercises and communication around key skills to help families support learning at home, including Guided Skill Supports (CC3e), Skill Builders and Tools & Topics letters (IC), and Infinite Practice.
Preview Videos
Video walkthroughs of each CPM course and chapter, ideal for understanding the storyline of the course and lesson planning. Currently available for Inspiring Connections.
Professional Learning
Comprehensive, ongoing PL from CPM's team of experienced teacher-educators, from Foundations for Implementation to leadership development.
