Equivalent fractions

Mathematics · Fractions · conceptual

Recognise and show, using diagrams, equivalent fractions with small denominators

What mastery looks like

  • Show that 1/2 = 2/4 using a diagram of equal parts
  • Use a fraction wall or bar model to find equivalent fractions
  • Explain why two fractions are equivalent by comparing the shaded areas

Check your understanding

If Equivalent fractions sees a bar divided into 4 equal parts with 2 shaded, can they tell you that's the same as 1/2 — and draw a different bar showing the same amount another way?
