Primary · Secondary · Sixth form
A class of thirty pupils has a syllabus to finish and a single pace. There is no time to look for different ways of explaining the same thing. Here there is.
A team of teachers frames each concept from different points of view. If deduction is not your child's way in, practice or imagery will be. We do not stop until we find the door that fits.
Repeating the same explanation more slowly or more loudly is not a new explanation. It is tripping over the same stone again. Here we change the approach so the concept clicks:
Deduce
Solve a real problem by anticipating the outcome.
Build
Handle the parts and watch the rule change live.
Visualise
Tie the theory to a drawing or an intuitive pattern.
Methodology in practice
📈 Functions and graphing

Functional inference and deduction
El Portero
From the algebraic expression of the function, the pupil must predict and anticipate the path of the curve to resolve a real-time vector interception.

Interactive parametric manipulation
Caza la Función
By changing the coefficients and independent variables one at a time, they see immediately how the slope, concavity and translation of the graph shift across the Cartesian plane.

Analytic geometry and spatial recognition
Trayectoria
By clearing obstacles within a coordinate system, the student identifies the right mathematical equation connecting different points of continuous space.
➕ Arithmetic and operational calculation

Synthetic modelling and number decomposition
Acércate
Instead of working through a set algorithm, the pupil reverse-decomposes a target figure by proposing their own terms and mathematical operators.

Sequential logic and algorithm solving
NumPath
Through a structure of graphs and logical mazes, each node demands an arithmetic operation whose accuracy determines whether the route remains viable.

Drilling, consolidation and assessment
Sums exam
Formative assessment aimed at consolidating automatic mental arithmetic, with step-by-step corrections explained instantly to fix learning without creating academic anxiety.
There is no single correct way to learn. Some minds get it straight away with a drawing, others with a number, others through deduction. What matters is not imposing a method, but giving your child options so they can pick their own.
Available for: Maths, Language, History, Geography, Physics, Chemistry, Biology, Geology, English, Music, Economics and Life Skills.
⏱️
"Class moves too fast"
A teacher with thirty pupils cannot stop to find a different explanation for each one. It is not their fault: there is no time. Here the topic waits as long as your child needs.
😑
"They get bored in five minutes"
Short rounds, coins, streaks and rankings. The same mechanics that hook them on video games, put to work in favour of their grades.
📉
"They study and still fail"
It is rarely a lack of hours; they did not understand it in the first place. Re-reading the same thing does not clear the doubt. Being told another way does.
💸
"Tutoring costs €150 a month"
And it means travelling and fitting the group's pace. Tuthor is free — all of it, with no paid plan behind it — whenever they want and focused exactly on where they struggle.
Built so the technology is neither a headache nor a risk at home:
🔑
No account or email for the child
You give them a short code, they type it and they are in. Nothing to remember and no passwords or emails to share.
📊
Progress by subject in real time
Check which topics they have worked on, how long they spent and the grades they get in their exams.
🔒
Full control
The child cannot reach the settings, the data panel or the subscription. It is all locked down on the server.
This is today's actual daily challenge — the same one any student sees. Answer it and see for yourself.

Every game, every exam and the whole teacher classroom, with no account, no card and no cut-down version waiting for you later. There is no paid plan: there is nothing to buy. If you still want to help, this is what actually helps.
Sign up to iGraal and get €10
Cashback on shopping you were doing anyway. You get the €10 welcome bonus and we get a commission. It is what pays for the servers.
SponsoredTell someone about it
Another parent, your child’s teacher, the class group chat. There is no advertising budget behind this: word of mouth is literally how people arrive.
A teacher? Use it in class
The classroom, grades, attendance and printable material are free with no cap on students. A real class using it is what tells us what to fix.
🤝School, publisher or ed-tech project?
If you work in education and see a way to get this to more people, write to us. We always reply.
And if you can do none of the four, that is fine: use it anyway. That is what it is for.
No. You create the account with your Google and all they get is a single access code.
It covers content adapted from primary school through to sixth form.
You can follow their progress from your own control panel.
There is no catch and no paid tier waiting for you: it does not exist. The site runs on ads and on people signing up to iGraal from here. If that ever stops covering it, we will say so before changing anything.
