Mental Math in the Classroom
A practical guide for teachers from elementary to middle school
A practical guide for teachers from elementary to middle school
A daily mental math routine — just 5 to 10 minutes — makes all the difference over the school year. The French national curriculum requires 15 minutes of daily mental math in grades 3–5, but in practice even a 5-minute morning routine is enough to see measurable progress within weeks.
The simplest format to set up. Launch a round of 10 questions in Normal mode at your class level. Students play on their tablet or computer. The leaderboard updates in real time on your screen.
How it works:
Ideal for: a daily routine with zero preparation. Works from CE1 (1st grade) to middle school.
On Fridays, launch a more ambitious challenge. Endurance mode (50 questions) or Time Attack (2 minutes). Students love comparing their scores week to week — and you can see who's improving.
How it works:
Ideal for: keeping motivation high. Students prepare all week for Friday's challenge.
A complete math session focused on mental math. Perfect during revision periods or to work on a specific topic (the 7 and 8 times tables, complements to 100, etc.).
How it works:
Ideal for: anchoring a specific concept. Plan 1–2 full sessions per month.
First thing in the morning works best. Students know they start every day with 5 minutes of mental math. No negotiation, no wasted time. Within 3 days, it becomes automatic.
Every Monday, note the class average score. Display it on the board. Typically, the class goes from 55–60% correct answers to 80% in 6 weeks. Students see the curve going up and it motivates them.
Monday: Normal mode (10 questions). Tuesday: Tables mode (a specific table). Wednesday: break. Thursday: Time Attack mode. Friday: challenge. Variety prevents boredom.
Class Battle is the format that surprises teachers the most. You pit two of your classes against each other for an entire week. Each day has a different theme: tables on Monday, addition on Tuesday, fractions on Wednesday…
Each student gets 3 attempts per day. Only their best score counts. Students practice on their own at home before playing their official attempt. On Friday, you announce the winning class.
Real-world result: students who never did math at home start reviewing their tables in the evening. Not because they're told to, but because they don't want to let their team down.
“My students love it — they keep wanting to compete against each other. Even the ones who used to hate math are getting into it. The morning routine has become their favorite moment.”— Christelle, teacher in Masseube, France
