Nell & Key

Math that plays like a movie.Real missions. Real confidence.

Does your child need help with math?

One rich mission a day, built on what they love, with a person who knows how they think.

Every mission is written for your child, acted out on screen with a voice, and checked by code and by judges before they play. What they tried shapes the next mission. A Book keeps every finished page for you to open together.

An example desk: a floating tower, a home island with the next mission, and a card for each of two roads, trumpet and Spanish, each with its own dragon.
One math mission a day, and a page in their Book.

What your child gets

  • Real-world math missions

    Each one starts from something they love and ends with an idea they can explain.

  • 1:1 mentors

    A tutor who knows how your child thinks, with time to ask why. Every plan has 1:1 classes.

  • Missions, not worksheets

    Every step is acted out on screen, with a voice. They try it, see it and explain it.

  • Growth you can see

    Each finished mission is a page in the family Book, with tutor notes beside it.

How it works

Three steps. Nothing is charged until after the call.

  1. Let's talk.

    Tell us what they love and where math sticks. Akshat calls to hear about your child.

  2. Meet the first mission.

    We build it around what they love, and code and judges check it before they play. They meet their tutor too.

  3. Keep growing.

    One rich mission a day, a Book you open together, and what they tried shapes what comes next.

Designed for Ages 6 to 14

Each mission is written for the child, at their level. Here are four you can meet today.

  • The lantern workshop: a pictured numbers mission.

Akshat Koirala

Founder and tutor

I began teaching in Nepal eight years ago. It showed me that math can be about curiosity and joy when it is connected to real life.

Our mentors have International Math Olympiad experience. For instance, Abhigya, one of our tutors, is pursuing a math PhD at UNC. Our story

Let's meet your family.

What do they love? What do they find tricky? Tell us a little, and Akshat will get in touch to plan their first mission with you. No payment here.

Monthly, per child, cancel any time. Nothing is charged here. We confirm the plan with you first.

Or talk to me first

Twenty minutes on a call: what your child loves, where math gets stuck, and whether Nell & Key is right for them. With a tutor this is the short fit conversation we begin with, not a free teaching hour.
