The right online maths tutor knows your child’s curriculum, finds the gaps before teaching, explains ideas in more than one way, and uses a shared whiteboard to see and correct every line of working. Maths is the most tutored subject worldwide, and the difference between a good and an average tutor is usually diagnosis: knowing exactly what’s going wrong. This guide explains how to choose well, for any curriculum.

Written by Tutopiya, an online tutoring company. The checklist applies to any maths tutor.

Key takeaways

• Match the tutor to the curriculum and level: primary, IGCSE, GCSE, A Level, IB or national systems.
• Good tutors diagnose before they teach; algebra and number sense are common root causes.
• A shared whiteboard lets the tutor see every step, which is maths tutoring’s biggest advantage online.
• Judge progress by topic tests and past-paper sections, not hours.

What should a good maths tutor do?

A good maths tutor follows a simple cycle: diagnose, teach, practise, check.

1. Diagnose: a few targeted questions reveal which skill is missing.
2. Teach: explain the idea, with more than one approach if needed.
3. Practise: your child works through questions while the tutor watches.
4. Check: a similar question without help confirms the fix.
5. Plan: set short practice for the week and choose the next topic.

Match the tutor to the curriculum

Maths content overlaps between curricula, but question styles and assessment don’t.

Curriculum	What a tutor must know	Browse tutors
IGCSE (Cambridge or Edexcel)	Tier, non-calculator papers, syllabus code	IGCSE Maths tutors
A Level	Pure and applied options, board	A Level Maths tutors
IB Diploma	AA or AI, HL or SL, the exploration	IB Maths tutors
Singapore primary and secondary	Heuristics, E Maths and A Maths	PSLE Maths tutors

For curriculum-specific guidance, see our guides to choosing an IGCSE Maths tutor, an A Level Maths tutor and an IB Maths tutor.

How to choose an online maths tutor

1. Confirm the curriculum, level and syllabus.
2. Gather recent tests with errors marked.
3. Ask the tutor how they diagnose gaps.
4. Book a trial lesson on the weakest topic.
5. Watch whether your child explains their thinking by the end.
6. Agree on practice and a progress check after six lessons.

Signs your child needs a maths tutor

• Homework takes much longer than it should.
• Your child can follow examples but not solve new questions.
• Marks are lost for missing working.
• Your child says maths “doesn’t make sense” or avoids it.
• Test scores have fallen after a move to a new topic or school.

What should the first lesson look like?

A useful first lesson starts with a quick diagnostic, then teaches one topic your child got wrong recently, and ends with a question they solve alone. If your child can do it, the lesson worked.

How much maths tutoring is enough?

One hour a week suits most students, with 20–30 minutes of practice between lessons. Students preparing for major exams, or with several gaps, may need two. Expect confidence to rise first, then accuracy, then marks.

Questions to ask an online maths tutor

1. Which curricula and levels do you teach most?
2. How do you diagnose gaps in the first lesson?
3. Do you use a digital whiteboard, and does my child need a stylus?

Common mistakes

• Choosing a tutor who doesn’t know the syllabus → confirm experience.

• Skipping foundations → fix algebra and number sense first.
• No practice between lessons → set short weekly tasks.
• Judging by hours → judge by improvement.

Frequently asked questions

What makes a good online maths tutor? +

A good online maths tutor knows your child's curriculum and level, diagnoses gaps before teaching, explains one idea in several ways, insists on clear working, and uses a digital whiteboard so they can see every step. They should also show you evidence of progress.

Is online maths tutoring as good as in-person? +

For most students, yes. On a shared whiteboard, the tutor watches each line of working and corrects errors immediately. Online tutoring also gives access to specialists in your child's exact syllabus, wherever you live.

What equipment does my child need for online maths lessons? +

A laptop or tablet, a camera and microphone, stable internet and a quiet space. A stylus or graphics tablet makes writing maths easier but isn't essential; some students simply hold their working up to the camera.

How quickly will my child improve with a maths tutor? +

Confidence often improves within a few lessons. Measurable improvement in test scores usually appears after six to ten weekly lessons, depending on the number of gaps and how much practice happens between lessons.
