This unit of work is Scale drawings.

Working with scale factors can be challenging for some learners, particularly where the principles of proportional reasoning have been taught in isolation and the association between them has not been made clear.

In this unit we emphasise the links between scale drawings and learners prior understanding of proportional reasoning.

We will develop learners’ ability to apply their understanding of scale drawings to real-life situations in a range of contexts.

Extended learners will also apply their understanding to interpret the effect on area of Scale drawings

This unit of work is just one of several approaches that you could take when teaching this topic and you should aim to adapt the resources to match ability level of your learners as well as your school context.
