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. Ensure the wholes you use are clearly defined.
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.
