What mastery looks like

  • Distinguish 'factor' from 'multiple' in a written explanation
  • Write an area answer as 48 cm² (not just 48) and a volume estimate as approximately 60 cm³
  • Use 5² notation correctly and read it as 'five squared'

Check your understanding

When Precise Maths Vocabulary talks or writes about maths involving primes, percentages, or polygons, do they use the precise technical words — like "prime factor", "obtuse angle", or "regular hexagon" — correctly and confidently?
