What equipment do you need for a truly smooth online maths tutoring session?

Before buying any equipment, start from what actually happens in the session: reading an exercise, writing an equation, showing a test paper, annotating a document and talking without losing time on technical settings.

The minimum needed for an online maths tutoring session

In maths, the quality of the session depends less on the webcam’s resolution than on the tutor’s ability to see how the student is reasoning. Giving only the final result provides little information: the interesting error is often two lines higher up, in a forgotten sign, a wrong transformation or an unjustified step.

Minimal equipment therefore needs to cover four needs:

• hearing and being heard clearly so as to reason out loud and ask questions;
• seeing the question and the materials without difficulty;
• writing maths legibly, on paper or digitally;
• showing that work to the tutor while it is being done or immediately afterwards.

Equipment	Priority level	Real use
Computer or tablet	Essential in practice	Display the session, documents and workspace in good conditions.
Microphone and speakers	Essential	Talk without turning every explanation into a technical problem.
Stable internet connection	Essential	Avoid drop-outs that interrupt the reasoning.
Exercise book, paper and pen	Very useful	Let the student keep writing naturally if they prefer paper.
Built-in camera	Useful	Make interaction easier and possibly show a sheet or document.
Headset or earphones	Useful depending on the setting	Reduce echo and hear better in a noisy room.
Stylus or graphics tablet	Optional	Make digital writing much more natural for equations, graphs and diagrams.
Second screen	Extra comfort	Display the video call, the whiteboard and a document at the same time without juggling windows.

This distinction matters: a student who already has a decent computer, an exercise book and a smartphone does not necessarily need to buy anything before their first session.

Computer, tablet or smartphone: which device for which use?

The computer: the most versatile choice

A laptop is generally the simplest set-up. Its screen keeps things at a comfortable size for reading an exercise, seeing the tutor and looking at a whiteboard or document. The keyboard and mouse also make it easier to open files and move between materials.

Its weakness shows when a lot of maths has to be written directly on screen. A mouse or touchpad is enough to circle a value, draw an arrow or add a short note; they quickly become awkward when you need to expand an expression, solve an equation over several lines or construct a figure.

The tablet: particularly well suited with a stylus

A tablet becomes very attractive when it works with a stylus. The student can then write almost as on paper while making their reasoning directly visible in the digital space used during the session.

It can even serve as the main device if its screen is large enough and the student is comfortable managing the session, documents and writing at the same time. For regular use, however, check that switching from a document to another view does not constantly slow the session down.

The smartphone: an excellent add-on, less good as the main device

A smartphone can do the job at a push for joining a session, but its small screen often forces you to choose between seeing the tutor, reading a document and following what is being written. For a long maths exercise, this constraint quickly becomes a nuisance.

It is, however, very useful as a second camera. Placed above or slightly to the side of a sheet of paper, it can show the tutor the student’s exercise book while the computer stays dedicated to the session. In that case, avoid leaving the sound on on both devices at once, or you will create an echo.

Writing maths: filmed paper, mouse, stylus or graphics tablet?

This is the technical choice with the greatest impact on a maths session. There are four main options, and none is always better than the others.

Filmed paper: the no-purchase option

The student keeps using their usual exercise book or sheets and shows their work with a camera. This option preserves school habits and works very well when set up properly.

The weak point is framing. A computer’s front-facing camera rarely shows a sheet lying flat properly. A smartphone on a stand can solve the problem. Before the session, check that the whole writing area is visible, well lit and the right way up for the tutor.

Mouse or touchpad: only for short annotations

They should not be underestimated for pointing to a term, circling an error or moving an element. On the other hand, writing a whole proof with a mouse often takes so much effort that the tool ends up disrupting the thinking.

The problem is not aesthetic. When the student has to devote part of their attention to managing to draw each symbol, the interface takes the place of mathematical reasoning.

A tablet with a stylus: the most direct digital writing

When the student already has a tablet that works with a stylus, there is usually no reason to buy an extra graphics tablet. Writing directly where the line appears greatly reduces the time needed to adapt.

This set-up is particularly comfortable for fractions, equations, functions, geometry figures or physics diagrams.

The graphics tablet: useful, but not compulsory

A graphics tablet connects to the computer and turns the stylus’s movements into writing on screen. It can be very effective for a student or tutor who works online regularly.

It does, however, take a little getting used to when it has no screen of its own: the hand writes on the tablet while the eyes look at the monitor. For a family simply trying out a first online session, it is therefore not an essential purchase.

The right rule is simple: only buy a writing tool if the current method genuinely prevents the tutor from following the student’s reasoning.

Sound, camera and connection: what really disrupts a session

Sound comes before image quality

An average camera generally lets the session carry on. A microphone that cuts out one word in three can make an explanation almost impossible.

So start with the computer’s or tablet’s built-in microphone. If it works properly in the usual room, no external microphone is needed. A headset or earphones become useful if there is echo or background noise, or when several people are working in the same room.

A studio microphone generally brings no particular teaching value to a one-to-one session.

An external webcam is usually not a priority

The built-in camera of a computer or tablet is usually enough for interaction. In maths, an ultra-detailed image of the face does not make an equation any easier to read.

Before buying a better webcam, check the lighting, the position of the screen and the method used to show exercises instead. If an extra camera does need to be bought, it may be more useful for filming a sheet of paper properly than for producing a more flattering image of the participant.

What internet connection do you need?

There is no single NOEO bandwidth figure to treat as a universal threshold. A video call also depends on the stability of the connection, the Wi-Fi network, other simultaneous uses and the device used.

As a benchmark — and not as a NOEO requirement — the Microsoft Teams network documentation gives about 1.5 Mbit/s upload and download as the recommended bandwidth for one-to-one video, with a similar order of magnitude for screen sharing. Above all, these figures show that a one-to-one session does not necessarily require an extremely fast fibre connection.

In practice, a connection advertised at several hundred megabits can still be unpleasant if the Wi-Fi drops out regularly. Conversely, a more modest but stable connection may be perfectly adequate. When a video call deteriorates, Google recommends in particular checking bandwidth and latency, trying a wired Ethernet connection where possible, or using 5 GHz Wi-Fi rather than a congested 2.4 GHz network.

Before an important session, the best test therefore remains very practical: start up the device in the exact place where the student will work, check the microphone and camera, open the documents and run a few minutes of video call.

Documents and exercises: prepare the files before the session

A good technical set-up is no use if the first ten minutes are spent looking for “the sheet the tutor gave out on Tuesday”.

Before the session, gather the documents that might be needed: the question, a photo of the homework, the lesson, the previous correction or an exercise to go back over. When a paper test needs to be sent, a sharp photo may be enough if the text is perfectly legible. For several pages, a scan or PDF is usually more convenient.

A few details avoid a lot of friction:

• photograph sheets lying flat and with enough light;
• check that all four corners of the page are visible;
• turn the document the right way up before sending it;
• avoid file names like “IMG_7842” when several exercises are being sent;
• open the main documents a few minutes before the session;
• keep the exercise book, a calculator if needed and something to write with within reach.

On NOEO, the online session is part of a journey before, during and after the session. In NOEO Live, the student and tutor can work on the same whiteboard with the session document in front of them. The equipment should therefore make this interaction easier, not recreate an unnecessarily complex workstation around the platform.

Three set-ups depending on the equipment you already have

Set-up 1: no extra purchase

• a laptop with a built-in microphone and camera;
• a stable Wi-Fi connection;
• an exercise book or sheets of paper;
• a smartphone available to photograph or film a test paper if needed.

This set-up is enough to get started. It makes it possible to check during the first sessions whether there really is an equipment problem before spending anything.

Set-up 2: improve the writing only

• a computer to follow the session;
• a headset or earphones if the sound in the room is poor;
• a small graphics tablet, or a touchscreen tablet with a stylus you already have;
• documents prepared before logging on.

This is often the most relevant improvement for a student who regularly takes online maths sessions. It acts directly on the ability to write, correct and share reasoning.

Set-up 3: a comfortable workstation for frequent use

• a main computer;
• a stylus or graphics tablet;
• a second screen if available;
• a headset or microphone suited to the setting;
• a smartphone or second camera to show a paper test from time to time.

A second screen is comfortable when it lets you keep the whiteboard on one side and a PDF or the question on the other. It is nonetheless a luxury: if a student wastes time with two poorly organised screens, a single screen used properly is better.

A 5-minute checklist before the first session

1. Start up the device that will actually be used during the session. Avoid discovering at the last minute that an update needs to restart the computer.
2. Test the microphone, speakers and camera. A recorded sentence or a quick call is already enough to spot most problems.
3. Open the main document. Check that it is legible and put the other useful files in an identifiable folder.
4. Test the writing method. Actually write an equation or three lines of calculation. A tool can seem suitable right up until you have to draw a fraction.
5. Check the connection from the exact place where the session will happen. If the Wi-Fi signal is weak in the student’s bedroom, knowing this before the session means you can change room or connection.
6. Prepare a simple plan B. For example, keep the smartphone charged and paper within reach. Plan B should be usable immediately, not require installing new software during the session.

If these six points work, there is rarely any need to go further for a first session. The equipment can then evolve based on an observed problem: tiresome writing, poor sound, a document that is too small or an unstable connection.
