CPM

CPM Educational Program, a California non-profit corporation, has provided problem-based instructional materials and professional development for teachers since its inception in 1989. 

CPM teaching strategies focus on how students best learn and retain mathematics. The research-based principles that guide the course are the following:

• Students should engage in problem-based lessons structured around a core idea.

• Guided by a knowledgeable teacher, students should interact in groups to foster mathematical discourse.

• Practice with concepts and procedures should be spaced over time; that is, mastery comes over time.Collaborative
