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 represent an equation in a part-whole model correctly.
Key Notes
- A representation helps to make sense of an equation or problem.
- A bar model can be used to represent an equation.
- A part-whole model can be used to represent an equation.
Vocabulary To Learn
- Represent: To represent something means to show something in a different way.
Common Mistakes To Avoid
- Pupils struggle to draw a bar model to represent an equation without a context.
3 Quick Questions (With Answers)
1. Solve this in steps: explain the method from this lesson and why each step matters.
A representation helps to make sense of an equation or problem. A bar model can be used to represent an equation.
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 struggle to draw a bar model to represent an equation without a context. Correction: Refer back to the language of parts and wholes to help pupils identify which numbers in the equation represent the parts and which number represent the whole. You may like to reduce the numbers to number within 10 to emphasise the structure at first.
