Everything you need to know to use Calcul Mental Challenge in the classroom.
In 7 simple steps, you're ready to run a mental math session.
Open the app on the teacher's computer (Windows or Mac).
Select "Teacher Mode" on the home screen.
Click "Launch a session" and configure the level and operation.
Students open the app on their devices and select "Classroom Mode".
They enter the address shown on your screen (same WiFi network required).
Launch the round once all students are connected.
View results in real time and the summary at the end.
With the class management system, track each student's progress individually.
In Teacher Mode, click "My Classes".
Create a class (e.g. "CM2-A (4th grade)", "6ème B (5th grade)").
Ask each student for their recovery code (visible in their profile).
Add each student to the class using their code.
Click on a student to see their detailed progress.
View their strengths, weaknesses, activity calendar and badges.
Pit two of your classes against each other for an entire week. Same concept as School Wars, but between your own classes.
In Teacher Mode, click "Class Battle" in the Class Management section.
You need at least 2 classes created in "My Classes" with students added.
Select the 2 classes to compete and click "Launch the battle".
Each day has a different theme (tables on Monday, fractions on Saturday…). Students play from the app, 3 attempts per day.
Scores update live. You can see which class is leading, the point gap and the top contributors.
Click "Detailed report" to see per-student rankings, teaching recommendations and history.
Scores are reset every Monday. History from previous weeks is preserved.
The report suggests actions: targeted sessions, encouragement, forming ability groups.
Students can see their contribution to the class score. The competitive spirit is guaranteed!
Launch a single-elimination tournament in your classroom. Asynchronous 1v1 matches with identical questions, 48 hours per round — the teacher has nothing to handle once the tournament is live.
Teacher mode → My classes → "Launch a bracket tournament" button.
Level, operation, style. The algorithm builds a bracket from your student list (sweet handling of byes for odd numbers).
Students play whenever they want during the 48-hour window. Async = no need to be online at the same time. Identical questions for both opponents.
Absent students auto-forfeit. The final winner unlocks the exclusive "Champion's Crown" avatar.
When creating homework, you can now target specific students instead of the whole class — perfect for differentiation (advanced students vs students needing remediation).
In local session mode, no data leaves the school network.
Windows, Mac, Android, iOS. Teacher mode works on desktop only.
All devices must be connected to the same school WiFi network.
