Our story
Mighty Mathletes started as a high school project with one goal: make practicing math facts something kids actually want to do. Here’s who built it, and how it got here.
Meet Ryan
Ryan Greenstein is originally from Deerfield Beach, Florida, and grew up in Queensbury, New York. He studies computer science at Rensselaer Polytechnic Institute (RPI), with a minor in architecture, which is also one of his great passions. Good buildings and good software have a lot in common: both should be sturdy, easy to find your way around, and a little bit delightful.
His favorite thing to do is cruise and travel the world. He has explored Europe, Asia and the Caribbean, sailed through the Panama Canal and cruised Alaska, and it’s no coincidence that one of the newest games, Anchors Away, has students running their own cruise line. When he’s on land, you’ll find him on the tennis court.
Ryan also earned a perfect 800 on the math section of the SAT. He mentions this only so you know who to blame if any of the answers in the games are wrong. After checking twice he can confirm they are correct.
More than anything, Ryan wants Mighty Mathletes to be known for two things: being a program that teachers and families can trust completely, and being one that makes kids laugh. Every game, every pet that tells a joke in the lobby, and every privacy promise on this site comes from those two ideas.
How Mighty Mathletes began
Development began on October 15, 2024, as Ryan’s CAS project for his International Baccalaureate diploma. The idea was simple. Kids need lots of practice to know their math facts by heart, and most practice is boring. What if every right answer did something: scooped ice cream, reeled in a fish, brewed a potion, or raced a car?
For a year, Mighty Mathletes was used at William H. Barton Intermediate School in Queensbury, New York. Many students used it, and they loved it. What they enjoyed, and what they and their teachers wished it could do, shaped much of what Mighty Mathletes is today.
The first version grew to more than a hundred thousand lines of code, with games, shops, challenges, avatars, friends lists, multiplayer games and a teacher dashboard. It also grew slow. So in October 2026, the Next Generation of Mighty Mathletes arrived: the whole program rebuilt from scratch as a fast app made for Chromebooks, where pages open in a snap and progress saves in the background.
The journey so far
- October 15, 2024The first line of code
Mighty Mathletes begins as Ryan’s CAS project for his IB diploma: a few games built to make math facts fun to practice.
- One school yearInto the classroom
The program is used for a year at William H. Barton Intermediate School in Queensbury, New York, by many students who loved it.
- Along the wayGrowing up
More games, avatars, pets, shops, friends, multiplayer, challenges and a teacher dashboard, built feature by feature from what students and teachers asked for.
- October 2026The Next Generation
Mighty Mathletes is rebuilt from the ground up as a fast app made for Chromebooks, with new games, the Quest, step-by-step lessons and much more.
What Mighty Mathletes offers today
- 15 games: 8 single-player games, 4 live multiplayer games with classmates, and 3 class-wide games the teacher opens for the whole class. See them all in why kids love it.
- The Mathlete Quest: a map of worlds to walk across, where every level is a set of challenges in the games, with treasure and souvenirs along the way.
- Step-by-step lessons for every skill, from addition to long division, so kids can learn a strategy and not just practice it.
- Practice that fits each child: addition, subtraction, multiplication and division, with ranges teachers and parents choose. A fact only counts as mastered after it’s answered correctly again and again.
- Rewards worth working for: MathBux to spend on avatars, pets, backgrounds, trophies and game passes.
- For teachers and schools: a dashboard with a plain-English summary of every student, fall, winter and spring check-ups, assignments and printables. More for schools.
- For families: a family plan for 1 to 6 kids with a parent dashboard. More for families.
- Safe by design: no ads, no tracking, no selling data, and New York Education Law §2-d agreements for schools. How we protect students.
Mighty Mathletes is still built by the same person who wrote the first line of code. If you have an idea, a question or a story about your students, he’d love to hear it.
