Bé Làm Toán ("Kid Does Maths") – learning maths is fun! Maths practice for children from preschool to middle school. Tap the bubble with the right answer, watch the octopus cheer, earn stars and beat your own best. Each round takes a few minutes: just the right size, with no pressure. LESSONS THAT MATCH THE SCHOOL YEAR Pick Preschool, Grade 1, 2, 3, 4, 5 or Middle school – each has its own course. A first-grader only sees one-digit sums and two-digit-plus-one-digit sums without carrying; carrying and the 2 and 5 times tables come in Grade 2. Every chapter says what it teaches, so parents can follow along. 20 TOPICS, ALMOST 400 KINDS OF QUESTION, OVER 4,000 LEVELS Every topic has 50 levels in 10 chapters: Warm-up, Practice, Step up, Review, Challenge. • Counting, comparing numbers, place value, Roman numerals, rounding • Addition, subtraction, multiplication and division – from picture sums for preschoolers to six-digit numbers and remainders • Measuring – telling the time, days of the week, money, cm, m, kg, litres, speed • Shapes & geometry – naming shapes, perimeter, area, volume, angles, Pythagoras • Word problems – more and fewer, times as many, sum and difference, averages, journeys • Logic – picture and number patterns, odd one out, balance scales, counting legs, magic squares, age puzzles • Fractions, decimals, percentages, solving for x, order of operations • Middle school: negative numbers, powers and roots, factors and primes, GCD and LCM GAMES • Today's challenge – 10 new questions every day; keep your streak going • 60-second sprint – how many can you answer? • True or false – is the sum right? • Three hearts – three mistakes and it's over, and it gets harder • Memory match – pair each sum with its answer • 2-player duel – two children race on one screen, each on sums for their own grade • Times tables – drill 2 to 10, then practise the facts your child keeps missing; a colour grid shows which ones they know by heart • Wardrobe – every star is a pearl to spend on hats, glasses and more for your octopus LEARNING THAT STICKS • Wrong answers are built from real mistakes (forgetting to carry, working left to right, adding tops and bottoms of fractions) so children learn why an answer is right • Mistakes are welcome: try again, and after two misses the octopus shows the way • Questions can be read aloud LEADERBOARDS • The whole family competes on this week's XP, all-time XP and total stars, with a podium for the top 3 • The weekly board resets every Monday, so every child has a shot at first place • Game Center leaderboards: compete with kids everywhere – no setup needed when the device is signed in to Game Center FOR PARENTS • Separate profiles for each child • A history of every round, with accuracy and practice time, and a 14-day chart • A "facts to practise" list of the sums your child gets wrong most SAFE FOR KIDS • Results stay on the device – no account needed. Only stars and XP go to Apple's Game Center, and a grown-up can switch it off • Ads are tagged as child-directed: not personalised, no tracking, and never shown during a round • Links out of the app and deleting data are behind a grown-ups question In English, Spanish, Portuguese, Indonesian and Vietnamese, for iPhone and iPad.
