Why this why now
This unit builds on pupils' understanding of fractions and multiplication to describe the relationship between two factors in a ratio context. They represent ratio in different ways and use the described relationship to calculate unknown values. They link ratio and proportion to scaling as used in maps and other contexts. Pupils also use scaling and positive scale factors to identify and describe the relationship between polygons. This work will be further developed in Year 7.
Prior knowledge requirements
- Use multiplication and division facts
- Recognise scaling in simple contexts
- Compare quantities and express multiplicative relationships
