Number Ninjas turns 3rd to 7th grade math into a game kids actually want to play. Pick the grade at sign-up. Daily training takes about 15 to 25 minutes; weekly boss battles earn belts; an endless Dojo, a weekly tournament, friend duels and career pathways keep them coming back when other apps wouldn't.
Our new Foundations track builds the core skills (place value, addition and subtraction, times tables, fractions, decimals and money) that get younger kids ready for the belt program. Same belts, boss battles and rewards, pitched right at their level. Just pick the grade when you sign up.
About 15 to 25 minutes a day, four short blocks.
5 quick-fire warm-up questions.
Read the lesson, then 8 practice problems.
Write down your score and one thing you noticed.
Teach today's idea back in one sentence.
A finite campaign to master, plus an endless arena that keeps even fast learners challenged.
A 10-week journey for 5th to 7th grade math, plus a Foundations track for grades 3 to 4 and an advanced track climbing toward 10th grade. Earn a belt for each skill mastered.
Four bite-sized blocks: a mental-math warm-up, a core lesson with practice, a data log, and teaching practice. About 15 to 25 minutes a day, with an energy meter that prevents over-grinding.
Each week ends in a Boss Battle. Score 80% or more to earn the belt and unlock the next week, with unlimited pressure-free retries.
Once the day's work is done, the Dojo Challenge ramps up forever: faster, harder, 3 lives. Difficulty starts near your current belt so it's always a real challenge.
Best Dojo run each week wins. Friends-only leaderboard, a Monday-to-Sunday race, and prizes that auto-pay when the new week starts.
Challenge a friend to a timed 10-question duel. Same questions for both, fastest correct wins. Kid-safe: friends only, no chat.
Pick a future-you (engineer, scientist, entrepreneur, game designer) and tackle hands-on mini-projects. Fresh randomized problems every replay, so it never gets stale.
Finish the program to earn a Certified Tutor badge, then run a real tutoring business with built-in tools and a younger-kid Foundations track to teach from.
Parents pick how prizes pay out: coins (default, in-app) or opt-in to Robux, V-Bucks, App Store gift cards, or cash. You set the amounts; the app tracks what's earned.
