Mathematics · Multiplication & Division · procedural

Solve multi-step word problems using the four operations with whole numbers, including interpreting remainders in context; represent with equations using a letter for the unknown; check with estimation

What mastery looks like

  • 52 children go on a trip in minibuses holding 9 each — how many minibuses are needed? (interpret remainder)
  • A shop sells packs of 6 pencils for £1.50 each — how much do 5 packs cost?
  • Represent a two-step problem with an equation using n for the unknown

Check your understanding

If Division with remainders reads 'a school buys 7 boxes of 24 pens and shares them equally between 8 classes', can they work through all the steps and decide sensibly what to do with any remainder?
