Collaborative Learning: Students learn ideas more deeply when they discuss ideas with classmates.
Problem-Based Learning: Students learn ideas more usefully for other arenas when they learn by attacking problems—ideally from the real world.
Mixed, Spaced Practice: Students learn ideas more permanently when they are required to engage and re-engage with the ideas for months or even years.
These pillars were synthesized from NCTM standards and research on constructivism in the early 1990s. The Three Pillars are still reflected in current NCTM standards and research in mathematics education; what we know about their benefits for mathematics learning continues to deepen and expand but not shift.
CPM curricula are grounded in an extensive and growing research base. This research base includes foundational educational research that supports CPM’s Three Pillars of Collaboration, Problem-Based Learning, and Mixed Spaced Practice.
CPM Educational Program results in meaningful mathematics learning for students and supports teachers to implement high quality instruction aligned with Common Core math content and practice standards.
CPM provides research briefs that synthesize current scholarship on various topics in mathematics education. Research briefs aim to connect parents, teachers, and administrators with research about mathematics education.

Dr. Tom Sallee, a mathematician and co-founder of CPM, reviewed and synthesized the research on mathematics learning in relation to each of The Three Pillars.

Collaborative Learning is a humanizing way to support students to engage in mathematical practices (i.e., the skills and dispositions necessary to participate in disciplinary discourse) for the production of mathematical knowledge and skills. CPM’s 2024 Report Research Base Collaborative Learning (PDF)
Problem-Based Learning supports students in learning mathematics in ways that will be useful to them in their future mathematics classes, in their careers, and in their lives outside of school and work. When students understand how to solve problems rather than how to correctly select and implement procedures, they develop mathematical authority and thus are more likely to enjoy and see the value in mathematics. CPM’s 2024 Report Research Base Problem-Based Learning (PDF)
Mixed, Spaced Practice supports students in developing mathematical dispositions in which they strive to make sense of problems rather than seek correct answers by mindlessly following procedures. Students will develop procedural fluency as they become increasingly proficient at identifying problem types and selecting appropriate problem-solving strategies.

CPM’s three-part lesson structure is geared towards supporting students to have agency in and take ownership of their learning. This is quite different from other three-part lesson structures such as the gradual release method of I Do / You Do / We Do.

This professional learning is designed for teachers as they begin their implementation of CPM. This series contains multiple components and is grounded in multiple active experiences delivered over the first year. This learning experience will encourage teachers to adjust their instructional practices, expand their content knowledge, and challenge their beliefs about teaching and learning. Teachers and leaders will gain first-hand experience with CPM with emphasis on what they will be teaching. Throughout this series educators will experience the mathematics, consider instructional practices, and learn about the classroom environment necessary for a successful implementation of CPM curriculum resources.
Page 2 of the Professional Learning Progression (PDF) describes all of the components of this learning event and the additional support available. Teachers new to a course, but have previously attended Foundations for Implementation, can choose to engage in the course Content Modules in the Professional Learning Portal rather than attending the entire series of learning events again.
The Building on Instructional Practice Series consists of three different events – Building on Discourse, Building on Assessment, Building on Equity – that are designed for teachers with a minimum of one year of experience teaching with CPM instructional materials and who have completed the Foundations for Implementation Series.
In Building on Equity, participants will learn how to include equitable practices in their classroom and support traditionally underserved students in becoming leaders of their own learning. Essential questions include: How do I shift dependent learners into independent learners? How does my own math identity and cultural background impact my classroom? The focus of day one is equitable classroom culture. Participants will reflect on how their math identity and mindsets impact student learning. They will begin working on a plan for Chapter 1 that creates an equitable classroom culture. The focus of day two and three is implementing equitable tasks. Participants will develop their use of the 5 Practices for Orchestrating Meaningful Mathematical Discussions and curate strategies for supporting all students in becoming leaders of their own learning. Participants will use an equity lens to reflect on and revise their Chapter 1 lesson plans.
In Building on Assessment, participants will apply assessment research and develop methods to provide feedback to students and inform equitable assessment decisions. On day one, participants will align assessment practices with learning progressions and the principle of mastery over time as well as write assessment items. During day two, participants will develop rubrics, explore alternate types of assessment, and plan for implementation that supports student ownership. On the third day, participants will develop strategies to monitor progress and provide evidence of proficiency with identified mathematics content and practices. Participants will develop assessment action plans that will encourage continued collaboration within their learning community.
In Building on Discourse, participants will improve their ability to facilitate meaningful mathematical discourse. This learning experience will encourage participants to adjust their instructional practices in the areas of sharing math authority, developing independent learners, and the creation of equitable classroom environments. Participants will plan for student learning by using teaching practices such as posing purposeful questioning, supporting productive struggle, and facilitating meaningful mathematical discourse. In doing so, participants learn to support students collaboratively engaged with rich tasks with all elements of the Effective Mathematics Teaching Practices incorporated through intentional and reflective planning.
