Times tables (age 8+)

Mathematics · Mathematical Thinking · meta

Recognise and use repeated reasoning to generalise: extend patterns in times tables and equivalent fractions, derive unknown facts from known facts efficiently, describe general rules

What mastery looks like

  • Notice that all fractions equivalent to 1/2 have a numerator that is half the denominator
  • Use the pattern 3×4=12, 3×40=120, 3×400=1200 and explain the generalisation
  • Derive 8×7 from 8×5=40 plus 8×2=16 and describe the strategy as a general approach

Check your understanding

When Times tables (age 8+) notices a pattern — like that multiplying by 4 is the same as doubling twice — do they use that generalisation to solve similar problems more efficiently?
