Why learn to subtract?

Subtraction tells you what’s left when you take one amount from another.

Quick tips for tutors

Subtraction includes:

  • Subtracting three-digit numbers.
  • Recalling Subtraction facts to 20.
  • Subtracting using efficient mental methods.
  • Subtracting using rounding.

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.
