Lesson details

Key learning points

1. Numbers 6 to 9 can be represented as two parts, one part of 5 and a smaller part.
2. Part-part-whole relationships can be represented as a bar model or on a number line.
3. A variety of representations, including a number line, can be used to explore the five and a bit structure.

Common misconception

Pupils may not connect more abstract representations of part-part-whole relationships with practical examples showing the five and a bit structure.

Take time to connect the representations pupils are familiar with e.g. show finger numeral representation alongside part-part-whole models and bar models to help pupils understand these all show the same relationship.
