Right angles

Unit 3 – 2 weeks

Primary KS2 Year 3

The PowerPoint file contains slides you can use in the classroom to support each of the learning outcomes for this unit, listed below.

Geometry topics are not covered by the NCETM Primary Mastery Professional Development materials. Therefore, some slides for this unit have been additionally created to provide the high-level overview to address each learning outcome. However, they do not provide the level of detail seen in other units, so teachers will need to supplement slides with other high quality materials available to them. You should also refer to the national curriculum to ensure coverage. There are also links to the ready-to-progress criteria detailed in the DfE Primary Mathematics Guidance 2020.

Learning outcomes

1 Pupils rotate two lines around a fixed point to make different sized angles
2 Pupils draw triangles and quadrilaterals and identify vertices
3 Pupils learn that a right angle is a ‘square corner’ and identify them in the environment
4 Pupils learn that a rectangle is a 4-sided polygon with four right angles
5 Pupils learn that a square is a rectangle in which the four sides are equal length
6 Pupils cut rectangles and squares on the diagonal and investigate the shapes they make
7 Pupils join four right angles at a point using different right-angled polygons
8 Pupils investigate and draw other polygons with right angles
