Maths Teacher Interview Questions UK: 8 Real Questions and What Interviewers Want

Applying for a Maths Teacher job in the UK? Here is what you are likely to be asked. These questions come from our Maths Teacher question bank of 25 questions, written for UK employers at mid-level level.

Eight Maths Teacher interview questions, and what the interviewer is thinking

1. How would you teach solving simultaneous equations to a Year 10 class, and what misconceptions would you expect?

Why they ask: A classic maths-specific teaching question that tests subject knowledge and pedagogy together.

2. How do you teach for mastery in secondary maths, and how does it differ from teaching to the test?

Why they ask: Mastery approaches shape the NCETM and many departments' schemes of work, so they want your understanding.

3. How do you approach teaching algebra, particularly for students who find it abstract?

Why they ask: Algebra is a gateway concept and a common barrier at secondary level.

4. Explain the structure of GCSE Maths, including tiers, and how you decide which tier a student should be entered for.

Why they ask: Tier entry is a high-stakes decision that every maths teacher must understand.

5. How do you use diagnostic questions and misconceptions in your maths teaching?

Why they ask: Assessment for learning in maths often relies on diagnostic questions, so they want practical examples.

6. A Year 8 student says 'I can't do maths' and refuses to attempt a task. What would you do?

Why they ask: Maths anxiety and fixed mindsets are common and they want to see empathy and strategy.

7. Tell me about a time you improved results or confidence in maths for a group of students.

Why they ask: They want evidence of impact in maths specifically.

8. Why do you want to be a maths teacher, and what makes a great one?

Why they ask: They want motivation and an understanding of the role.

A sample answer to question 1

How would you teach solving simultaneous equations to a Year 10 class, and what misconceptions would you expect?

I would start from what students know, solving a single linear equation, and use a worked example with a concrete context, such as the cost of two items, so that two unknowns feel natural. I would introduce elimination first with matching coefficients, modelling every step and narrating my reasoning, and then move on to multiplying one or both equations, with substitution as an alternative. I would use the worked example effect: showing a full solution, then partially completed ones, then independent practice with carefully varied questions. Common misconceptions include subtracting when they should add with negative terms, only multiplying one side of an equation, or forgetting to substitute back to find the second variable. I would use mini whiteboards to catch these early, and show students how to check by substituting into the original equations. Later, I would link it to graphs, where the solution is an intersection.

Common mistake to avoid: Teaching a procedure without meaning; ignoring sign errors
