Recognise, compose, decompose and manipulate 2D and 3D shapes

Unit 4 – 3 weeks

Primary KS1 Year 1

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.
