TGT Maths interview questions and answers (2026)
TGT Maths interview prep for CBSE and ICSE schools — panel questions, model answers, and a Class 9 or 10 demo lesson plan the panel actually rewards.
What this interview actually looks like
An honest breakdown of how Indian schools run this interview — not a generic template.
- 1Written test (30 min) — Class 9 and 10 problems, one geometry proof, one word problem.
- 2Demo lesson (15–20 min) — Class 8, 9 or 10. Topic given the same day.
- 3Subject panel (20 min) — HOD Maths + one senior teacher. Expect a 'how would you teach X' question.
- 4Principal / HR round (15 min) — school fit, salary, joining date.
- Two printed CVs + one lesson plan you've actually taught
- Original B.Sc, B.Ed, CTET / state TET certificates
- Your own whiteboard marker + a small geometry set (compass, protractor)
- One printed problem you can teach cold in 5 minutes
Questions with model answers
Grouped by round. Each answer is 2–4 sentences — long enough to be real, short enough to remember. Dots show how often each is asked.
What they're really asking — Can you make the abstract concrete?
Number line, then temperature, then bank balance. Draw the number line horizontally with 0 in the middle — the student already accepts positives on the right; negatives are just the mirror. Then: 'if the temperature drops from 3° to −5°, how many degrees did it drop?' Then: 'if you owe someone ₹200 and you have ₹100, what's your balance?' Three real contexts and the concept sticks.
What they're really asking — Can you deliver a clean board proof under time pressure?
Draw triangle ABC. Draw a line through A parallel to BC. Mark the alternate angles: angle equal to B on one side of A, angle equal to C on the other. Together with angle A on the top, they form a straight line — 180°. State the alternate-angle theorem as you use it, don't skip. Say the proof aloud while drawing.

Panels don't score creativity — they score structure, board work and closure. This is the skeleton that works.
- Class 10 — Arithmetic progression: finding the sum of first n terms
- Class 10 — Similarity of triangles with a Basic Proportionality Theorem proof
- Class 9 — Linear equations in two variables (graphical method)
- Class 9 — Area of a triangle using Heron's formula
- Board work — clean layout, labels, units
- Cold-calling students by name
- Talking through your thinking
- Time management
- One clear takeaway
A real question — 'how many bricks in a triangular stack?' or 'how tall is the school tree using shadows?' — before naming the topic.
State the rule / formula on the board. Draw the diagram if geometric.
One problem, thinking aloud. Show every step, no shortcuts.
A variation problem. Circulate — do not sit at the desk.
Cold-call two students for the key idea. Close with a board-style prompt.
Ask them back — questions for the interviewer
Most candidates freeze at “do you have any questions for us?” These signal that you take yourself seriously.
- How many periods per week does a TGT Maths teacher get?
- What's the typical class size for Maths — and are there any streamed sections?
- Do you run any Maths Olympiad prep (NMTC, PRMO)?
- What's the CPD budget for subject workshops?
- How is progress measured — board results, unit tests, or peer observation?
- What's the appraisal cycle?
