For teachers & parents
The whole learning circle
Teachers and parents have their own role in OpenMath. Here is exactly how you get one, how you link a child, and what the role lets you do.
Four roles, and who hands them out
Student
The default role. Anyone a teacher or a parent invites arrives as a student.
Teacher
Assigned by an admin. Sees the students linked to them, reads back their rounds, hosts games for the class.
Parent
Assigned by an admin. Follows the children linked to them and signs off on their rounds.
Admin
The project owner. Assigns roles, invites teachers and parents, manages quiz types and invitation quotas.
Getting in
OpenMath is invitation-only
There is no open sign-up page. That is deliberate — it is a children’s app, and we would rather know who is in it. Three steps, and none of them involve waiting for an email.
- 1
Get an invitation link
You can’t sign yourself up. Someone who already has an account creates an invitation for your email address and hands you the link in person or in a message. No email is sent — don’t sit and wait for one. The link is valid for 30 days.
- 2
Register with that exact address
The invitation belongs to one email address. Use a different one and it is refused. Google sign-in exists in the app but is switched off in production — the button says so.
- 3
Ask an admin for the role
You can’t choose to be a teacher or a parent when you register. An invitation from a teacher always creates a student. Only an admin can set the teacher or parent role — so tell us which one you need. Better before your first lesson than during it.
The link looks like app.openmath.hu/register?code=… — a one-time code, good for 30 days.
⚠️ An invitation is not a class list
Being invited by a teacher does not put you in that teacher’s class. Linking is a separate second step: the teacher adds the student afterwards, by email address. The student gets a notification in the app and can see who is linked to their account. A parent adds a child the same way — and either side can be undone.
So a child who already has an account doesn’t need a new invitation. They just need to be added.
🍎 What a teacher gets
- Your class in one list — Add a student by their email address. They get a notification in the app and can see that you are linked.
- Any round, question by question — Open a finished quiz and read it back: what was asked, what they answered, what was right.
- Written feedback they actually read — Leave a review on a finished round. It shows up for the student.
- A notification when they finish — Every time a linked student completes a quiz, you hear about it.
- Badges and mastered topics — See what they have collected and which topics they now have under control.
- Games for the whole class — Host a live multiplayer round — you set it up and run it from a live board.
- Invitations from your own quota — Five by default. Everyone you invite arrives as a student.
👪 What a parent gets
- Add your child by email — They get a notification and can see who is linked to their account.
- Accuracy and speed over time — Not just today’s score — how both move, round after round.
- Badges and mastered topics — See what they have collected and where they are already solid.
- Any round in full detail — Read it back question by question, and export it as a PDF.
- Sign off on a round — One tap tells your child that a grown-up looked.
- Unlink whenever you want — You made the link, you can remove it — at any time.
🎮 Running a game
A live race for the whole class
Hosting is not a teacher privilege — any account can host a game. But it was built with a classroom in mind, so here is the host’s side of it before you try it in front of a full class.
- You set it up: quiz type, difficulty level, how many questions, the time penalty for a wrong answer (5, 10 or 20 seconds), and the smallest and largest number of players.
- The app hands you a short code like MATH-A7X. The kids type it in and wait in the lobby, where they can chat and flip a ready switch. You start when everyone is ready.
- You don’t play — you run the game. While the round is on you watch a live board: every player, every question, right or wrong as it happens.
- If a tablet drops out, the child has 30 seconds to come back. The app reconnects on its own and puts them back exactly where they were.
- At the end: a podium, then a full scoreboard with each player’s time and the penalty seconds they picked up. Every game stays in a history you can reopen.
🛡️ No ads. No third-party tracking.
OpenMath is made for children, so it keeps almost nothing: a name, an email address, and the child’s progress. No advertising, no profiling, and nothing sold or shared for marketing — ever. Visits are counted by our own self-hosted Plausible: no cookies, no request to any third-party network. As a teacher or a parent you only ever see the students or children linked to you.
Privacy, plainly →Want to try it with your class?
OpenMath is being piloted with real primary-school classes. If you teach grades 2–4 — or you are a parent who wants it at home — tell us, and we will set up the invitation and the role for you.
