Lesson details

Key learning points

  1. If the hundreds digit is smaller than the divisor then it is exchanged for tens and included with the tens digit
  2. If the 100s digit is smaller than the divisor then no partial product is recorded above the 100s digit of the dividend

Keywords

  • Dividend - What we are dividing.

  • Divisor - What we are dividing by.

  • Quotient - The result after division has taken place.

  • Regroup / Regrouping - The process of unitising and exchanging between place values.

Common misconception

Pupils may confuse the terminology of dividend and divisor. Pupils may regroup the incorrect amount.

Ensure pupils can identify the dividend and the divisor. Use language of unitisation to correct any place value misconceptions.

A quick recap / game of the inequalities signs will be helpful. In doing so, pupils will understand that if the divisor is greater than the 100s digit in the dividend, this will result in a 2-digit quotient.
