Popo Math: Play & Learn

No points off for mistakes. Every right answer makes the screen and music livelier! In times tables and column math, see WHY you slipped and get it next time. No ads.

The more you play, the more you love math.

Popo Math is a math practice app where you train with cute buddies. Its content follows the Japanese elementary math curriculum, grades 1 to 6. Every right answer makes the confetti, lights and music livelier, and the last question is a big party! Mistakes never cost points, and hints and pictures appear, so anyone can make it to the end.

■ It gets livelier with every answer Right answers add Sparkle, and the effects and music power up step by step. Rounds are short, so "One more!" comes naturally.

■ 58 units In curriculum order: making 10, carrying, times tables, division, decimals, fractions, mixed numbers, telling time, units of length and volume, rounding, factors and multiples, ratios, solving for x and more. You can also pick a unit to practice.

■ Real column math Like on grid paper, write one box at a time, starting with the ones place. You write the carries and borrows yourself, and long division goes divide → multiply → subtract → bring down. Once you get good, carries fly up on their own.

■ Find out WHY it was wrong The app recognizes the kind of mistake (a forgotten carry, a times-table mix-up, a remainder that's too big, the decimal point in the wrong place…) and explains it with a short tip and a picture (ten frames, dot arrays, blocks, fraction bars).

■ Step by step until it clicks New units are solved one step at a time, the way the textbook does it. Once you know them, answer in one go.

■ Times Tables map and Time Attack The 81 squares light up one by one as you learn them. Race each table and beat your best time.

■ A review just before you forget The app tracks every single problem, and an algorithm based on memory research (FSRS) schedules reviews automatically. Missed problems go to the Mistake Notebook.

■ Little things that make you come back Daily missions, daily stickers, a streak calendar, trophies and a collection.

■ 4 buddies cheer you on Pick your favorite: Popo, Hamu, Pyoko or Penta.

■ Three languages Japanese, Simplified Chinese and English — switch in Settings.
