Justifying mathematical reasoningMeta concept
Check understanding
- Explain step by step why a columnar addition method gives the correct answer
- Find and explain an error in a worked example (e.g. incorrect regrouping)
- Construct a simple argument for why a general statement is true (e.g. 'adding two even numbers always gives an even number')
“If your child hears another child's explanation for how they solved a maths problem, can your child say whether the reasoning makes sense — and if not, point out exactly where the logic goes wrong?”
