Identify structures within stories and use knowledge of structures to create stories
Lesson details
Learning outcome
I can identify structures within stories and use knowledge of structures to create stories.
Key learning points
- Bar models can represent the maths in a story or problem.
- A story can represent the maths presented in a representation.
- The structure of the maths can be represented by a model or a story.
Keywords
Represent - To represent something means to show an idea or concept. One concept can be represented in multiple ways.
Additive - Additive means related to addition. An additive structure is one that is composed by adding parts.
Multiplicative - Multiplicative means related to multiplication. A multiplicative structure is one that is composed by multiplication.
Common misconception
Pupils struggle to identify appropriate sized bars that fit the problem as well as equate to the size of the whole.
Find parts that fit the structure of the problem first, then ask what the whole would be. Change the size of the whole and ask pupils which rod(s) would need to change. Encourage children to reason their decisions by comparing the size of the rods.
Teacher tip
Ensure pupils regularly articulate what each rod represents in relation to the problem. To deepen thinking, can pupils show you the same structure of the problem using a different set of coloured rods?
