Lesson details

Key learning points

  1. If the tens number is not a multiple of the divisor then the remainder is recorded next to the ones digit.
  2. If there is a remainder after dividing the tens digit the tens are exchanged and the ones digit becomes a 2-digit number
  3. If the number of ones, including any exchanged tens, is not a multiple of the divisor, there will be a remainder.

Common misconception

Working through algorithmically without having an understanding of the regrouped amount.

Clear modelling with PVC. Ask children 'What does this number represent?'. Continue to use sentence stems.

Keywords

  • Remainder - A remainder is an amount left over after division (happens when the first number does not divide exactly by the other).

  • Regroup / regrouping - The process of unitising and exchanging between place values is known as regrouping.

At this stage it is important to highlight that if the ones is not a multiple of the divisor, there will be a remainder. Encourage children to think about whether short division is the most efficient strategy compared to mental strategies.
