Why this why now
This unit builds on and formalizes knowledge of angles as a measure of turn and as properties of 2D shapes. Pupils classify and define acute, obtuse and reflex angles, identifying them in shapes and using them to classify shapes. They calculate missing angles, using knowledge that there are 360 degrees in a full turn and also use an angle measurer or protractor to measure and construct angles. This will be built on as they learn to draw construct shapes in the future.
Prior knowledge requirements
- Identify right angles
- Compare angles using visual tools
- Estimate angle size using known benchmarks

Angles: compare, name, estimate and measure angles
In this unit pupils will compare the size of angles where there is a clear visual difference and use the terms acute, obtuse and reflex when describing the size of angles or amount of rotation with relation to right angles using a unit called degrees.
