All Grades: Lesson Types

P: Problem Solving

Problem Solving Lessons help students and teachers realize the CCSSM requirement that “(Students) take an active stance in solving mathematical problems.” These lessons are designed to assess and develop students’ capacity to apply their mathematics flexibly to non-routine unstructured problems, both from the real world and within pure mathematics.

C: Concept Development

Concept Development Lessons help students and teachers realize the CCSSM requirement that “Proficient students expect mathematics to make sense.” These lessons are designed to reveal and develop students’ conceptions, and misconceptions, of significant mathematical ideas and how these connect to their other knowledge.
