Math Practice is designed to help your child practice what they have learned in our main app, Math age 3-5 - covering the same ten topics, but with all-new activities and graphics. Each topic features several fun games and activities, intended to consolidate learning through repetition and practice, followed by a quiz to test the child’s knowledge, and a certificate when they get all the questions right. Our math apps have been proven to be effective. An independent study by the University of Nottingham in the UK showed that 6 weeks of using the onebillion math app was as effective as 18 months of standard classroom practice. In fact, one week of using the onebillion software for 30 minutes a day equalled three months of formal education. As a nonprofit organisation, all of our app proceeds go directly to delivering transformational education to young children around the world, in their own language.

Parents can follow progress, practice weak spots and print worksheets with answer keys. No ads, no subscription. A universe your child lights up with their own mind Lumi Math Planet turns math into a warm, cinematic space adventure. Solve a puzzle and a dark little planet flickers to life — buildings rise, auroras bloom, and an adorable space friend floats down to say hello. From Glimmer Planet all the way to the Boss Planet, every right answer makes the universe a little more beautiful. No failure. No buzzer. No shame — only gentle encouragement. So confidence grows on its own. Children ask to play it. That's the part that changes everything. Crafted to a standard you can feel Every planet has its own glowing personality. Every object is sculpted in warm, clay-style art. Every question is read aloud in a gentle, friendly voice. This isn't a worksheet with a cartoon stapled on top — it's a tiny world built with the kind of love you'd want a great teacher to have. Thinking, not just answers — contest-grade Most math apps drill speed. Lumi builds minds. Our question styles are inspired by the world's great early-math challenges — WMI and Math Kangaroo among them: number patterns, logic, spatial reasoning, simple combinatorics, real word-problems. Your child learns to think like a young mathematician, right at the kitchen table. So clear, a child plays before they can read Every single question is visual. Dice, ten-frames, number lines, growing rows, bar charts — abstract math becomes a picture you understand at a glance. No memorizing. No guessing. Just real number sense, discovered. From the very first number to contest-grade thinking Addition & subtraction past 100 (with regrouping), multiplication, division, number bonds, place value, comparing, patterns, odd/even, ordinals, time and money — 40+ question types that level up automatically. Whether it's a pre-reader, a child just starting school, or anyone rebuilding their foundations, everyone begins right at their own level and climbs from there. Growth you can actually see The Parent Zone shows learning across five skill domains, spots weak areas, and opens one-tap focused practice. Export a printable worksheet and a learning report (print it or save a PDF) and carry every milestone with you. Four native languages English · Chinese · Japanese · Korean — questions and voice fully localized, auto-matched to your device. The quiet luxuries No ads. Ever. No data collected — nothing ever leaves the device. No account, no login. Every outbound tap sits behind a parent gate. One promise, kept: a single one-time in-app purchase. No subscription, no nagging. Start without buying with your first planet and the daily challenge; unlock the whole galaxy whenever you're ready. Blast off — and watch your child build a universe that runs on what they just learned. (Question styles are inspired by international early-math contests for practice only; not affiliated with WMI, Math Kangaroo or any organization.) Optimized for iPhone Duo.
