Lesson details

Key learning points

  1. Number lines and scales represent fractions in a continuous context.
  2. The whole has been divided into __ equal parts and the line shows __ of them.

Common misconception

Children need to understand that fractions can also be fractions of 1 and have an exact position on a number line. There may be confusion over labelling an exact point rather than a part of the line.

Use the language of labelling a point on the line and avoid talking about 'half of the line' which is the language of parts of a whole. This helps children to see that fractions are numbers in their own right with a unique position on a number line.

Keywords

  • Continuous - Continuous means that every position on the line or scale has a value.

  • Equal - Equal means that something has exactly the same amount or value.
