Calculonautes: a mental math game set in space
Calculonautes is a space-themed mental math game for Android where each school year from Grade 1 (CP) to Grade 5 (CM2) is a planet and each skill is a station to conquer. A mission is 10 calculations while the fuel gauge slowly empties.
The questions come from the French primary curriculum.
It is made by the Mathovore teachers and has no ads.

Why a mental math game works with worksheets
Younger children often resist repeating the same calculations. A space mission changes the mood: the calculation is the same, but the child is now an astronaut with a fuel gauge to protect. That makes it easier to add a few minutes of practice next to a printed worksheet.
Parents who print a weekly page from the Grade 3 section can let the child play a mission or two as a reward once the page is finished.
Features
Planets and stations
There are 5 planets, one per year from Grade 1 to Grade 5. Skills include number bonds to 10, doubles and halves, addition and multiplication tables, working with tens and hundreds, multiplying by 10 or 100, decimals, simple fractions and short word problems.
Game modes
- Missions: 10 calculations with a timer, a fuel gauge and personal records
- Mission of the day: 12 mixed calculations with double experience points
- Meteor shower: destroy the calculations before they hit the base
- Two-player duel on the same screen, each player at their own level
Rewards and support
- More than 50 badges, 12 astronaut ranks, stars and streaks
- A calculation tip after each mistake
- Visual aids for the youngest: dots, fingers, tens and units, coins and notes
- A progress screen showing play time, strengths and skills to train
Getting started
- Install Calculonautes from Google Play.
- Let the child choose an astronaut helmet.
- Pick the planet that matches the school year.
- Play one 10-calculation mission.
- Open the progress screen together and choose the next skill.
Tips for a weekly routine
Keep it to two or three missions per session. The questions are drawn at random and get harder as the child improves, so replaying a station is never identical. Use the progress screen to choose which topic to reinforce with a paper worksheet.
Language and platform
The game is in French and English, with no ads. Progress is saved to a Google account and can be restored on another device. It runs on Android phones and tablets, and an iPhone version is in preparation.
What parents can watch
The progress screen is the most useful part for an adult. It shows how long the child played, the success rate for each type of calculation, the strengths and the skills that still need training. A parent can read it in half a minute and then decide what to print.
- If addition tables are weak, print a simple practice sheet on them
- If word problems are weak, read one aloud together before the next mission
- If everything is solid, move the child up to the next planet
The duel mode is also a pleasant family moment, because each player keeps a level that suits them.
