Lesson details

Key learning points

  1. Each of the numbers six to ten can be partitioned into two parts in different ways.
  2. A part-part-whole model or a bar model can be used to represent the whole and the parts.
  3. If we know one part we can find the other part.
  4. Knowing about odd and even parts means you know if the missing part is odd or even.

Common misconception

Pupils are not yet fluent in number pairs and partitions of numbers 6 to 10 and so rely on counting to find missing parts.

Develop subitising skills so that pupils are able to recognise small partitions instantly. Encourage choral repetition of stem sentences emphasising wholes and parts.

Keywords

  • Partition - To split a whole up into parts.

  • Whole - All of something. Complete.

  • Part - A piece or section of a whole.
