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.
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.
Keywords
