- Expressions can be used to express the combinations of different parts of the whole.
Common misconception
Pupils may look at each rod as representing a number rather than focusing on the colour.
Remind pupils that the rods have no numerical value and encourage pupils discuss the rods by their colour name. They may notice proportional relationships but these should not be labelled numerically.
