This unit of work is Unit conversions

Unit conversions can be a difficult topic to teach because students often learn rules without really understanding how they work and are then unable to apply these rules independently and in more complex, less familiar situations. Learners often think of different types of conversion as completely different topics and do not make the wider link to proportional reasoning.

We are going to look at how to use different units of mass, length, area, volume and capacity in practical situations and express quantities in terms of larger or smaller units.

We are also going to interpret and use graphs to inform our understanding of direct proportion linked to conversions, applying our understanding in practical situations

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.
