MA2-GM-03, Angles and right angles

Stage 2 (Years 3 and 4) ยท Mathematics ยท Geometric measure

Identifies angles and classifies them by comparing each to a right angle.

MA2-GM-03 is an outcome from the NESA Mathematics K-10 Syllabus (2022), taught in NSW schools. Because Stage 2 spans Years 3 and 4, the worksheets below come from Year 3 and Year 4. Print them as PDFs, or generate a fresh one. Every maths answer key is computed in code, so it is never wrong.

Teaching guide

What students learn

Identifies angles and classifies them by comparing each to a right angle.

How to teach it

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).

Worked example
Find the area.
Answer: 30
Why: 2 ร— 15 = 30

Generated and checked in code, so it is correct.

Watch out for

Confusing perimeter and area, and judging a shape by its orientation rather than its properties.
