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.
If pupils are unfamiliar with number rods, ensure pupils take time to play with the rods and explore them for themselves, becoming familiar with how they can represent equivalence. Online tools could be used to allow pupils to manipulate number rods.
