• Curriculum Overview: IM K–12 Math is a problem-based core curriculum built on the principle that all students are capable learners of grade-level mathematics. Students learn math by doing math. They are encouraged to use their current understanding of math, their lived experiences, and the world around them as resources for problem-solving. By starting with what students already know, teachers invite all students to contribute to mathematical learning, centering student thinking, and being responsive as students develop conceptual understanding.
