Fractions, Decimals & Percentages

Mathematics · Mathematical Thinking · meta

Look for and use mathematical structure: exploit the relationship between fractions, decimals, and percentages; use factor pairs to simplify multiplication; apply angle facts to find unknowns; use properties of regular polygons systematically

What mastery looks like

  • Use the structure 25 × 16 = 25 × 4 × 4 = 100 × 4 = 400 by exploiting factor pairs
  • Recognise that 0.75 = 3/4 = 75% and use whichever form is most efficient for the problem
  • Use the fact that angles on a straight line sum to 180° as a structural tool to find missing angles

Check your understanding

When Fractions, Decimals & Percentages notices that fractions, decimals, and percentages are just different ways of writing the same thing, do they use that understanding to switch between them fluidly when it makes a calculation easier?
