THE PROGRAM

What is Kani Math?

Kani Math is a complete mental-arithmetic curriculum built on the soroban (the Japanese abacus). Children first master the physical abacus, then learn to picture it in their mind — a decades-old training path that produces rapid, accurate mental calculation. Kani reimagines that curriculum as a cosmic journey. Every exercise, every milestone, every leaderboard exists to make the practice feel like play — without compromising the rigor of the method.

🧠

Mental math, built to last

Visualizing the abacus rewires how children process numbers — improving focus, memory, and calculation speed long after the program ends.

Abacus-first foundation

Every concept starts on a real abacus widget — counting, small friends, big friends, multi-row, multiplication, division — before moving to mental form.

🎮

Playful, not childish

Galaxy map, boss battles, versus mode, coins, streaks, daily missions. Game mechanics that reward consistency, not just correctness.

📊

Measurable progress

Parents and teachers see streaks, accuracy, speed, and level progression in dashboards built for adults — not just emoji and fireworks.

🌐

Arabic & English, side by side

Every lesson, every mission, every dashboard is fully bilingual with proper RTL typography. Switch language any time — progress and settings stay intact.

👨‍👩‍👧

Built for families

Parent dashboards, time limits, daily quotas, and a separate teacher face for classroom use. One account can hold multiple kids on the same device.
