Calculonautes: Mental Math

Calculonautes turns mental math into a space adventure. Your child becomes a calculonaut: they pick an astronaut helmet, take off and explore the galaxy. Each grade is a planet, each skill of the curriculum is a station to conquer. 10 calculations per mission, a fuel tank that runs down… and stars to win! • 5 planets from Grade 1 to Grade 5, with skills based on the official French curriculum: number bonds to 10, doubles and halves, addition and times tables, working with tens and hundreds, multiplying by 10 or 100, decimals, simple fractions, word problems… • Always new questions: they are drawn at random every game and get harder as you progress • Time matters: stopwatch, fuel gauge, personal records to beat on every mission • Daily mission: 12 mixed calculations, double XP • Meteor shower: destroy the calculations before they crash into your base! • Two-player duel on the same screen, each with their own grade • More than 50 badges that explode on screen, 12 astronaut ranks, stars and streaks • After a mistake, a mental math tip explains how to do it • My progress: time played, success by type of calculation, strengths and skills to practise • Visual aids for the youngest: dots, fingers, tens and ones, coins and notes • Great sound effects, on phones and tablets • In English and French • No ads Progress is saved to the Google account and restored on another device.
