Why learn about number lines?

To help think about sums, sketch a line. Draw jumps along the line to show adding and subtracting.

Quick tips for tutors

Number lines include:

  • Recognising that number lines may be empty or numbered and that the numbering may be continuous or go up in simple multiples.
  • Recognising that number lines may be used to add and subtract.
  • Finding the difference by counting on and counting back.
  • Matching calculations to diagrams of number lines.
  • Using a number line to add and subtract whole numbers, and decimals including money.
  • Finding the difference between positive and negative numbers.
  • Carrying out time calculations.
  • Recognising number lines may be marked with fractions or decimal numbers.
  • Using double number lines to do conversions and find equivalents between fractions, decimals and percentages.
  • Recognising that number lines can also be used for multiplication by repeated addition or division by repeated subtraction.

What do the levels mean?

Skillswise uses the levels of the National Qualifications Framework, which start at Entry 1, 2 and 3 and then go on to Level 1 and Level 2.

  • Entry 3 covers the basic concepts and is a good preparation for starting a Level 1 course.
  • Level 1 is roughly equivalent to a GCSE D-G grade in England, Northern Ireland and Wales, and a Foundation level at Standard Grade in Scotland. A useful qualification for many jobs.
