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

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.
He opens each lesson, works one example step by step, and explains why the math works.
Sol spots the likely mix-up and gives a gentle clue, never the answer.
Blue opens a picture of this very problem: a number line, an array or fraction strips. He also says hello here.
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.
Here is what your child sees after tapping “Start the adventure.”



Screens from the current game, played with a made-up demonstration profile.
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.
Every grade is a set of worlds. Each world has a few levels and a Boss Nest challenge. Topics are organized around the New York State Next Generation Mathematics Learning Standards for grades 2, 3, 4 and 5.
A short placement check can start your child at the right spot, and earlier worlds are always there to revisit.
Professor Kairos works one example with your child, step by step, before practice begins.
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.
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.

Pick a grade and tap an answer. It takes less than a minute.

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.
Kairos brings math adventures together with Bible moments that invite children to know God’s Word and put it into practice.
Try a little moment of encouragement together.

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


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.
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.
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.
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.
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.
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.
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.
A contact address for families is on its way. It will appear here.
For growing minds. For joyful hearts.
