EVERY LITTLE STEP COUNTSYour adventure is taking flight.

A little movie. A big hello from Blue.

I spy… a happy little friend!

Sol has his binoculars ready. What has he spotted?
It’s Coco, enjoying a delicious millet snack!

SOL’S LITTLE DISCOVERY

A curious friend. A tasty discovery.

Wonderful things happen when we look a little closer.
Try a little discovery of your own →

Never stuck on a wrong answer.

Meet the flock: one patient teacher and three budgie helpers. When a problem gets tricky, the help grows one step at a time. Your child also picks one budgie as their own companion.

  1. 1THE LESSON

    Professor Kairos

    He opens each lesson, works one example step by step, and explains why the math works.

  2. 2A WRONG TRY

    Sol

    Sol spots the likely mix-up and gives a gentle clue, never the answer.

  3. 3STILL TRICKY

    Blue

    Blue opens a picture of this very problem: a number line, an array or fraction strips. He also says hello here.

  4. 4STILL STUCK

    Coco

    Coco solves it together with your child, one step at a time, and also leads the Bible moments.

Then a twin problem with new numbers, solved alone, shows the idea has really landed.

Pick a buddy. Make a new friend.

A little practice. A whole world to discover.

Here is what your child sees after tapping “Start the adventure.”

3Care for and customize your budgie’s nest.Feed your budgie, give it a bath, and decorate its treehouse with the seeds you earn.

Practice math
Earn seeds and stars
Care for your budgie
Explore new worlds

Seeds buy food, baths and decorations for the nest. New worlds open when your child passes a world’s Boss Nest challenge, never by spending seeds. Nothing in the game is sold for money.

What your child practices.
How you can follow along.

How practice, feedback and rewards work

1

A short lesson first.

Professor Kairos works one example with your child, step by step, before practice begins.

2

Help that grows with the need.

A wrong answer gets a gentle hint. If it is still tricky, a picture model comes next, then a step-by-step walk-through and a similar problem to try.

3

Rewards for effort and mastery.

Finished levels earn seeds, and even a try that doesn’t pass earns a few. One to three stars show accuracy. Speed is never the main score, and there is a 15-minute daily goal.

SAMPLE QUESTION
MULTIPLICATION · EQUAL GROUPS

Four little bowls. Three seeds in each.
How many seeds can the flock share?

Professor Kairos

Look closely. Count your way to a discovery.

Also on the grade 3 journey: number sense, division, fractions, measurement, and more.

This is just a sample. Nothing is saved here, and you don’t need an account.

More than answers.
Room to grow with God.

Kairos brings math adventures together with Bible moments that invite children to know God’s Word and put it into practice.

  • A verse of the day each time your child starts playing, with a “Read it to me” button.
  • Bible story missions. Four Boss Nest challenges come from Scripture: the walls of Jericho, the census in Numbers, feeding the 5,000, and the Tabernacle courtyard. Every number comes from the verse.
  • Kindness, courage and encouragement. The budgies cheer effort and trying again. The moments here give your family a question to talk about.

Try a little moment of encouragement together.

Verses come from the World English Bible, the Reina-Valera 1909 and the 개역한글 (Korean Revised Version), all in the public domain, and from the Nova Versão Transformadora (NVT © 2016 Editora Mundo Cristão, used by permission).

A LITTLE WORD TO GROW WITH
“And be kind to one another, tender hearted, forgiving each other, just as God also in Christ forgave you.”
Ephesians 4:32 · World English Bible
TAKE IT INTO YOUR DAY

Someone gets an answer wrong. What is one kind thing you could say to help them try again?

Good questions.
Practical answers.

Is Kairos free, or does it cost anything?+

Kairos Math Adventures is free to play right now, with no ads and no in-app purchases. Seeds are earned by practicing, never bought.

We plan to offer a paid subscription in the future. Before anything changes, we will explain it here, and your child’s saved progress stays on your device.

Where is my child’s progress saved?+

On the device you play on, inside your web browser. It is not sent to us. If you clear this website’s data in your browser, the progress is erased, so download a backup from the Parents area from time to time.

Can we continue on another device?+

Yes, with a backup file. There is no automatic sync. In the Parents area, open “Reports and data,” export a backup, then import that file on the other device. Progress is combined by student and date.

Do we need an account?+

No. There is no sign-up and no email address. Each child picks a picture and a 4-digit PIN, and a grown-up sets a 6-digit PIN for the Parents area. The PINs only lock profiles on that device.

Which devices and browsers can we use?+

Kairos is made for iPad first, and it also runs on iPhone, Android tablets and phones, and Windows, Mac or Chromebook computers, in a current version of Safari, Chrome, Edge or Firefox. After the first visit the game also works offline, and you can add it to your Home Screen.

How do math and faith fit together?+

Math adventures give children a reason to practice. Bible moments, like the verse of the day and the Bible story missions, introduce God’s Word and encourage kindness, courage, gratitude and perseverance. Families can use those moments to start a conversation.

Is Kairos right for my child?+

Kairos is made for children working on second- to fifth-grade math. Each grade includes review worlds to revisit foundations. Try the sample above, then open the game together. It is a way to practice alongside teaching, books and pencil-and-paper work, not a replacement for them.

How can we contact you?+

A contact address for families is on its way. It will appear here.

Come curious.
