Calcul Mental is an Android app for mental math practice that covers 76 skills from grade 1 (CP) to grade 7 (5ème). It trains students for a few minutes a day, in the order in which each skill is taught in class.
Reliable estimation is the first tool of any experimenter. This page shows how a student of physics and chemistry can use short daily sessions to build it.

Who this app helps
Primary students from grade 1 (CP) to grade 5 (CM2) follow the path of their year, while middle school students in grade 6 (6ème) and grade 7 (5ème) revisit decimals, fractions and relative numbers.
Parents also like the short sessions. A child can finish a mission while waiting for dinner, which suits the regular, brief practice that builds speed.
Why mental math matters in science classes
A physics result that looks wrong is often caught by mental estimation: a speed of 3000 metres per second for a walking person tells you to check the units. Skills like powers of ten, percentages and proportions appear in every lesson of our physics and chemistry courses.
Before tackling the AP Physics 1 worksheets, a week of Calcul Mental sessions on fractions and decimals makes the arithmetic part of each problem much less tiring.
Following the adventure path of a school year
Each class has its own path, arranged in the order in which notions are taught. A pupil in grade 3 starts with tables and complements, while a pupil in grade 6 (6ème) meets decimals, fractions and percentages.
Stars and experience points reward effort, and the 15 ranks give a long-term goal. The 40 badges mark milestones such as a first perfect training or a long streak of days.
Families can use the daily challenge as a shared moment: everyone gets the same 15 questions on the same day, so a parent and child can compare results after dinner. The records page keeps a personal best for each skill.
Tips for steady progress
- Play one short session each day rather than one long session each week.
- Use the daily challenge as a warm-up, then spend the rest on your weakest skill.
- Say the trick from the tip aloud; explaining a method helps it stick.
- Estimate the answer before you type it, as you would before a measurement.
Frequently asked questions
What does Calcul Mental teach?
Calcul Mental trains mental calculation on 76 skills from grade 1 to grade 7, including multiplication tables, decimals, fractions, percentages, order of operations and relative numbers. Each year has its own path of skills.
What game modes does it offer?
There are four: training with ten questions on one skill, a 60-second time attack, a survival mode with three lives, and a daily challenge of 15 questions identical for all players on a given day.
Is Calcul Mental in English?
Yes. The store description says the app is available in French and in English. School years follow the French system, so grade 6 appears as 6ème and grade 7 as 5ème, and the app was designed by the Mathovore team.
Does it show why an answer is wrong?
Yes. After a mistake the app displays the correct answer together with a mental calculation tip, for example a way to go through the nearest ten. This turns each error into a small lesson.
