n Learning and Teaching Mathematics - Building students' mathematical proficiency : connecting mathematical ideas using the Tangram

Abstract

This article describes a classroom-tested approach that brings together different sub-domains of secondary school mathematics using the Tangram: Number Sense and Algebra (unpacking the idea of a square root and irrational numbers, understanding a reverse relationship between area and side length of a square); Geometry and Measurement (spatial reasoning, understanding properties of geometric shapes, measuring area and length).
