Lesson details

Key learning points

  1. Division means splitting into equal parts or groups.
  2. Skip counting in the group size can be used to calculate the number of equal groups in a division story.
  3. We say 50 divided into groups of 10 is equal to 5
  4. We can write 50 ÷ 10 = 5

Keywords

  • Division - Division means splitting into equal parts or groups.

  • Multiple - A multiple is the result of multiplying a number by another whole number.

Common misconception

Pupils may think that the 'divisor' (the number we are dividing by) always represents the number of groups.

Avoid generalising the divisor as the 'number of group' for every division problem, explaining that this only works in contexts in which grouping takes place. For sharing problems later in the unit, the divisor is the 'size of each group'.

Pupils could use number rods with number lines or rulers to support calculating throughout the session. For Task B, pupils could be challenged to find the number of animals with 15 legs as only seastars could have a total of 15 legs.
