Lesson details

Key learning points

  1. Skip counting in steps of the divisor can be used to divide 2-digit numbers.
  2. Dividends can be partitioned into multiples of the divisor to divide efficiently.
  3. Unitising language is used to describe the process of division.

Common misconception

Some children may continue to share one by one when dividing.

Encourage children to skip count in the divisor and remind children that it is an efficient way of dividing.

Keywords

  • Dividend - The amount that you want to divide up.

  • Divisor - The number you divide by.

  • Partial quotient - Part of an answer to a division equation.

  • Partition - Splitting an object or value into smaller parts.

  • Quotient - The result after division has taken place. It is the whole number part.

Model clearly using language of unitisation, ask children to join in when modelling language. Use concrete resources to exemplify structure of division. Remind children that partitioning the dividend gives us partial quotients.
