Make math visual with a dynamic instructional routine and collaborative graphic organizers. The Concept Circle Thinking Routine (CCTR) invites students to explore and discuss a math concept through multiple representations, including manipulatives, drawings, numbers, words, and symbols.
A central math concept is placed in the center of the Concept Circle, and students represent the idea in multiple ways. They discuss and connect their representations to deepen mathematical understanding and build mathematical language. The routine encourages explanation, questioning, and justification. This routine honors diversity of thinking, values all mathematical voices, and teaches how mathematics can be represented and understood in different ways. By creating diverse representations and showing relationships in the concept circle, students strengthen their understanding of mathematical concepts while identifying patterns and connections.
Designed by an educator and researcher for K-12 classrooms, intervention groups, centers, and enrichment, this flexible routine helps students engage in meaningful math discourse.
Suggested Concepts
- Counting, Number Sense, and Place Value
