MA3-2DS-01, Classify triangles and quadrilaterals
Stage 3 (Years 5 and 6) · Mathematics · Two-dimensional spatial structure
Investigates and classifies two-dimensional shapes, including triangles and quadrilaterals, by their properties.
MA3-2DS-01 is an outcome from the NESA Mathematics K-10 Syllabus (2022), taught in NSW schools. Because Stage 3 spans Years 5 and 6, the worksheets below come from Year 5 and Year 6. Print them as PDFs, or generate a fresh one. Every maths answer key is computed in code, so it is never wrong.
Teaching guide
Investigates and classifies two-dimensional shapes, including triangles and quadrilaterals, by their properties.
Sort and name 2D and 3D shapes by their properties (sides, angles, faces), then build up to perimeter (add the sides) and area (cover with unit squares).
Generated and checked in code, so it is correct.
Confusing perimeter and area, and judging a shape by its orientation rather than its properties.
