Unit Summary
In this unit pupils will identify the mathematical structures within stories and use their knowledge of additive structures to create stories and to solve problems.
Lesson Summary
You will learn to create stories to match structures presented in a model.
Key Notes
- The story and the model can represent the same mathematical structure.
- The same mathematical structure can apply in different contexts.
- Different stories can match the same structure.
Vocabulary To Learn
- Represent: To represent something means to show something in a different way.
- Addends: Addends are any numbers added together.
Common Mistakes To Avoid
- Pupils create bar models where the parts do not equal the whole or vice versa.
3 Quick Questions (With Answers)
1. Solve this in steps: explain the method from this lesson and why each step matters.
The story and the model can represent the same mathematical structure. The same mathematical structure can apply in different contexts.
2. Use this key word in a maths sentence and explain it clearly. 'Represent'
To represent something means to show something in a different way. Use this word when showing your method, then check your final answer is reasonable.
3. Spot and fix this common maths mistake.
Mistake: Pupils create bar models where the parts do not equal the whole or vice versa. Correction: Whilst this may be a calculation error, it is important that the context of the story is considered when looking to re-adjust the bar model. Take time to work through the context again building the bar model from the what is known.
