Lesson details

Key learning points

  1. A part must be part of a whole.
  2. If __ is the whole then __ is part of the whole.
  3. The whole can be different in different situations.

Keywords

  • Whole - The whole is all the parts or everything, the total amount.

  • Part - A part is some of the whole.

Common misconception

Children may think that a part only needs to be something smaller than the whole and not part of it.

Spend some time identifying wholes in the classroom and then get the children to identify a part of it. Get the children to play games involving spotting non-examples to strengthen their understanding - Paris is an example of this in the slides.

This lesson makes use of examples from Geography as well as more familiar contexts such as the classroom. Consider your pupils and adapt images and contexts as required to suit their needs and experiences.
