Geometry for Singapore primary maths
Look for shape properties, perpendicular heights and equal angles. Use diagrams to explain area and perimeter, explore symmetry and nets, and connect circles and solids to measurements.
Choose your primary level and path. Each guide links to the interactive lesson and its prerequisite ideas.
