In this section, we illustrate the developmental trajectory for fractions. This illustration is indicative of the progression with some milestones illustrated along the way.

The NumberSense Mathematics Programme learning trajectory for the development of the fraction concept assumes that there are a number of interrelated concepts within the overarching concept of fractions. For the primary school years these are:

- The existence of a part of a whole: the fraction
- Naming of fractions and fraction notation (social knowledge)
- Comparing fractions
- Awareness of the equivalence of fractions
- Operations with and involving fractions
