Using the measure model

The measure construct of fractions requires some different thinking about fractions than the commonly used part-whole idea. Watch the video Fractions as Measures.

Using the measure model for fractions supports understanding of several important aspects of fractions.

  • Thinking of a fraction as a number is a critical component of developing a sense of the size of a fraction in relation to other fractions.
  • Using linear models as a tool for exploring equivalent fractions utilises the concept of subdividing a fraction (as a unit of measure) into smaller units.

Using the number line model supports the process of adding and subtracting fractions, by counting forward or back along the number line.
