Explaining Mathematical Reasoning
With teacher prompting, explain and justify mathematical reasoning using drawings, number sentences, or words
Suggested ages 6–7
Learning journey
Your child is developing mathematical reasoning skills — learning to plan approaches to problems, explain their thinking clearly, spot patterns, and connect real-world situations to mathematical solutions.
Evidence of understanding
- Explain a solution strategy using a drawing or number sentence (e.g. 'I made ten first, then added the rest')
- Justify why an answer is correct by showing an alternative method that gives the same result
- Identify and explain an error in a worked example or a peer's solution
Assessment prompt
If you ask Explaining Mathematical Reasoning "how did you work that out?", can they show you with a drawing or explain their steps in simple words?
