- To calculate the value of a part, we need to divide the whole by the number of equal parts.
- To calculate the the number of equal parts, we need to divide the whole by the value of each part.
- To calculate the whole, we need to multiply the number of equal parts by the value of each part.
- Drawing a bar model helps us to visualise the problem.
Common misconception
Children may struggle to make connections between division and the value of a part.
Support children to understand and describe what they know from the information given, for example, the whole, the size of a part, or the number of parts. Also, what it is that they are trying to find. Encourage representation as a bar model.
