Common misconception

Pupils confuse the fraction part of each whole with the value of the number of items in each part.

Progressively build from looking at the size of each part in relation to the whole using bar models to start with. After pupils are secure with this, introduce the quantities and be clear to distinguish between the value and size of each part.

Ensure clarity with your language when talking about the number of items in each part and the size of each part in comparison to the whole. For this lesson, we refer to the number of items as the value of the part, and the fractional part we refer to as each part's size in comparison to the whole.
