Identify acute and obtuse angles; compare and order angles up to two right angles by size
Suggested ages 8–9
Learning journey
Your child is advancing their understanding of shapes and space — working with coordinates on grids, identifying different types of angles, exploring symmetry, and classifying shapes by their properties.
Evidence of understanding
- Classify given angles as acute, right, or obtuse
- Order four angles from smallest to largest by visual comparison
- Identify all acute and obtuse angles in a given triangle or quadrilateral
Assessment prompt
If Types of angles looks at the hands on a clock showing different times, can they tell you which angle between the hands is acute (sharper than a right angle) and which is obtuse (wider)?
