Show and tell how a mathematical answer was found using objects, drawings, and spoken words

What mastery looks like

  • Use objects or drawings to demonstrate how an addition or subtraction was solved
  • Respond to 'how do you know?' by pointing to objects or a drawing and describing what was done
  • Listen to a peer's explanation and say whether they agree or disagree

Check your understanding

After Showing Your Working solves a maths problem, can they explain how they got their answer — using counters, a drawing, or words — rather than just writing down the final number?
