Lesson details

Key learning points

Partitioning can be represented on a part-part-whole diagram.
A bar model can be used to represent ways to partition numbers into two parts.
The larger the number the greater the number of combinations.
Being systematic helps you to find all the ways of partitioning a number.

Keywords

Systematic - Having an order to the way we work, identifying and using patterns.
Partition - To split a whole up into parts.
Part-part-whole model - A pictorial representation of a whole and its parts.

Common misconception

When using patterns to identify combinations, pupils may struggle to be systematic and not identify all options systematically.

Spend time exploring the value of recording combinations within a simple table. Encourage checking, e.g. the amount of counters totals eight. Look for patterns and support children in spotting these.

Children may try finding all possible combinations through trial and improvement. Encourage more systematic thinking, using reasoning and discussion to spot patterns in both concrete and abstract representations.
