GCSE Maths Justify Questions
Justify questions ask students to support an answer with evidence. This might involve a calculation, comparison or written reason.
How To Justify an Answer
- State your answer clearly.
- Show the calculation or evidence.
- Explain why the evidence supports your answer.
- Use units or labels where needed.
Exam tip: Think of justify as “prove your answer is reasonable”.
Common mistake: Giving an answer without evidence may not receive full marks.
