Solve a range of problems, including finding change
I can use efficient and reliable strategies to solve problems involving money, including finding change.
Lesson details
Key learning points
- Informal calculation strategies such as rounding and compensating can be applied to calculating with money.
- 'Same sum' and 'Same difference' can be applied to calculating with money.
- Column addition and subtraction can be used to calculate with money but is not always the most efficient strategy.
Keywords
Representation - A representation is a way of showing a mathematical idea. Concrete objects, pictures and symbols can all be used to represent mathematics.
Common misconception
Pupils can sometimes see words like 'altogether' in a problem and assume it is an addition problem.
Provide lots of examples of contextualised problems and focus on mathematical language, including where it might be misleading.
Drawing a bar model alongside a word problem helps pupils to understand which words relate to which operations. Pupils struggling during the practice tasks may benefit from further bar models.
