What mastery looks like

  • Choose a mental method for 345 + 200 but a written method for 345 + 278
  • Select a ruler vs a metre stick based on the object being measured
  • Decide when a number line is more useful than base-ten blocks for a given problem

Check your understanding

When Choosing the right strategy faces a maths problem, do they think about which method suits it best — like doing easy ones in their head, using a written method for bigger calculations, or sketching a diagram for geometry?
