Lesson Summary
You will learn to use efficient strategies and common measure conversions to solve problems in a range of contexts.
Key Notes
- Use known facts to solve problems involving measures.
- Use informal methods such as partitioning and bridging to solve problems involving measures.
- Convert between units of measure to simplify problems.
Vocabulary To Learn
- convert: To change a value from one form to another, such as converting 1 m into 1,000 mm
Common Mistakes To Avoid
- Pupils may need support to identify the operation(s) involved in solving a problem and when a problem is presented with mixed units and it is necessary to convert one of them.
3 Quick Questions (With Answers)
1. Solve this in steps: explain the method from this lesson and why each step matters.
Use known facts to solve problems involving measures. Use informal methods such as partitioning and bridging to solve problems involving measures.
2. Use this key word in a maths sentence and explain it clearly. 'convert'
To change a value from one form to another, such as converting 1 m into 1,000 mm. Use this word when showing your method, then check your final answer is reasonable.
3. Spot and fix this common maths mistake.
Mistake: Pupils may need support to identify the operation(s) involved in solving a problem and when a problem is presented with mixed units and it is necessary to convert one of them. Correction: Read the problems aloud. Ensure that children identify the operation(s) involved and see this as a clear step in solving the problem. Emphasise the units of measure so that attention is drawn to them and they identify whether conversion is needed.
