MathKnights is the math companion that adapts to your child —
seven domains of practice for Grades 1-5, kid-safe sign-in, and the only coins
they spend are the ones they earn.
No credit cardAdaptive lessonsKid-safe sign-inNo in-game purchases
I'm Knight Mathbot. When your child gets stuck, I explain — not "try again."
✦♛✦
What your knight gets
A math companion that actually adapts.
MathKnights isn't a flat curriculum. Every quest is picked from where your child
actually is — and when they get one wrong, they learn why.
🎯
Adaptive learning
Every question is chosen from your child's current level — never too easy, never frustrating. The system watches what they get right and wrong, and picks the next batch accordingly.
💡
AI-powered explanations
When a question goes wrong, Knight Mathbot explains it in your child's language — with visuals. Not "Try again." Real understanding.
⚔️
Seven math domains
Operations, Geometry, Time, Money, Measurement, Algebra, and Statistics. Real coverage of the Grades 1-5 curriculum, not just arithmetic drill.
📊
Parent dashboard
See exactly which domains they've mastered, where they're stuck, and the specific questions they got wrong. Use it to start a real conversation.
🛡️
Kid-safe by design
Children sign in with a 4-digit PIN — never your password. Knight names are display-only. Real names, emails, and contact info are never required.
🪙
No predatory monetization
Coins are earned, never bought. There's nothing to nag you to upgrade. The in-game shop is part of the fun, not a sales pipeline.
⚜
How it works
Three steps. About five minutes.
No download. No setup wizard. No app store. Open the page, make a profile,
hand the screen over.

Lesson videos
When practice gets hard, the lesson is right there.
Every question is tied to a short concept lesson. Tap a tricky one;
the lesson opens, your knight watches, then jumps back to it with
the idea fresh.

The reward beyond the lesson
After the math, the adventure.
Castle Run 3D is the kingdom your knight unlocks by passing math quests
at grade level. A four-realm voxel platformer that opens up as the work
gets done — and every gem they pick up in the castle becomes a coin
they can spend back in the shop.
Realm IV · The Tower
I.
The Approach
Sun-bright fields and voxel trees. Learn your footing and gather the first scatter of gems.
II.
The Moat
Dark water rings the keep. Sea creatures circle in the shallows — time the jumps carefully.
III.
The Castle
Inside the great halls. Dragons drowse over the gems and gold they've been hoarding.
IV.
The Tower
A long climb past a giant spider. At the very top, a princess waits to be freed.

Common questions
Everything else parents ask.
What ages and grades is MathKnights for?
MathKnights is built for Grades 1-5. The adaptive system adjusts difficulty to your child's level automatically, so kids progress at their own pace whether they're ahead, on track, or stretching into tougher topics.
Do I need to download or install anything?
No. MathKnights runs in any modern browser on any device — laptop, Chromebook, tablet, phone. There's nothing to install, but you can add it to your home screen for a full-screen, app-like experience.
Can I use it for more than one child?
Yes — on the Premium Family plan you can add up to 4 knight profiles, all under one parent account. Each child has their own PIN, avatar, progress, and dashboard view. Free Basic supports a single profile. Need more than 4 for a classroom or larger family? Contact sales about a school plan.
What if my child is ahead of (or behind) their grade level?
The adaptive system handles this. It watches what they get right and wrong, then picks each batch from where they actually are. A grade-2 student who's strong on operations but struggles with time will get more time questions automatically — and a grade-1 student ahead of their peers won't get capped.
How is my child's data handled?
We're COPPA-compliant. We never sell or share child data. Knight names are display-only — your child's real name is never required. Emails and contact info are never collected from kids. The only personal data tied to your account is the parent email you signed up with.
Are there ads or in-game purchases?
No ads. No real-money purchases. The in-game shop only spends coins your child has earned by answering questions. Premium upgrades happen in the parent portal — never inside the game where kids could trigger them.
Can I cancel anytime?
Yes, two clicks in Manage Billing on your dashboard. If you cancel mid-cycle, you keep Premium access until the end of the current billing period. Then your account reverts to Free Basic — your data and history are preserved.
Is there a school or district option?
Yes. We offer school and district licensing with bulk pricing. Classroom and teacher tools are on the roadmap — reach out at sales@mathknights.com and we'll work with you on what you need.
♛

Ready to send them on their way?
Free Basic, no credit card. Add a knight in a couple minutes. Upgrade or cancel anytime.
Here's a real sequence. Your child gets one wrong, and the next question doesn't punish them — it scaffolds. The adaptive engine isn't about difficulty levels; it's about meeting them where they are, then nudging up.

Instead of grinding through more division-with-remainder questions, the engine drops to a simpler division the child can solve, then reinforces the multiplication facts that division depends on. Same domain, different angle. Confidence stays intact.
After the assessment
When your child finishes a placement assessment, you get this report — emailed and saved to your dashboard. It's the same report your child sees, written in plain language for parents.
On grade level. Penelope is solidly placed at Grade 3 across most domains, with a few areas to practice and one she's stretching ahead on.

Heads up: Algebra placeholder questions ("find the missing number") are a stretch right now. Adaptive engine is dialing back to easier patterns.
Sample data — your real dashboard updates after each quest your child plays.
Coverage
Seven domains. Real curriculum. Real questions.
Most "math apps" drill addition and call it adaptive learning. Here's what your child actually encounters across MathKnights — one real example pulled from the question bank for each domain.
🧮
Operations
Number sense, place value, addition through long division, fractions, decimals.
Reading clocks (analog & digital), elapsed time, schedules, calendars.
Sample question · Grade 4
A timer is set for 90 seconds. How many minutes and seconds is that?
→ 1 min 30 sec
🪙
Money
Counting coins and bills, making change, real-world purchases, savings.
Sample question · Grade 3
A book costs $4.50. You pay $5.00. How much change?
→ $0.50
📏
Measurement
Length, weight, volume, temperature, units and conversions.
Sample question · Grade 3
A worm is 4 inches long. A stick is 1 foot long. How many inches longer is the stick?
→ 8 in
🔢
Algebra
Patterns, missing numbers, equations, word problems with unknowns.
Sample question · Grade 3
35 sweets are shared equally among 5 friends. How many each?
→ 7
📊
Statistics
Reading tables, bar charts, line plots, and pictographs to answer real questions.
Sample question · Grade 3
Look at the bar chart. How many votes did Pizza get?
→ 7
Every example above is a real question from the MathKnights bank, aligned to Florida B.E.S.T. and Common Core standards.
Kid-safe by design
The least amount of data a child can possibly give.
This is the actual sign-in screen your child sees. Every field was chosen deliberately. Here's what's on it — and what's not.

1
Parent email — read-only
Shown so the child knows whose household account they're signing into. They can't type, change, or send to it.
2
Knight name — display only
"Penelope" is whatever you set when you created the profile — first name, nickname, made-up character. No last names, ages, or schools ever required.
3
4-digit PIN — chosen by you
A simple PIN your child can remember. Never your password. Resettable anytime from the parent dashboard.
4
"Begin Quest" — no terms checkbox
No agreements aimed at children. No "I'm over 13" boxes. All legal consent happens on the parent side when you create the account.
What's NOT on this screen
No email field for the child. No phone number. No real name. No age. No school. No "social" prompts. No third-party login (Google/Apple/Facebook) buttons on the kid sign-in screen.
Beyond what's on the screen
🚫 No third-party advertising. No data sales. Ever.
We don't run ads. We don't sell or share your data. The only way MathKnights makes money is the parent Premium subscription — your child's behavior is not the product.
⚖ COPPA-aligned design from day one
The Children's Online Privacy Protection Act (COPPA) governs how online services collect data from children under 13. MathKnights is designed to minimize what falls under it: by collecting nothing personal from children, most of those rules simply don't apply.
The shop your child sees vs. the shop you've seen before.
Most kid math apps have an in-game shop. So do we — but here's what's in ours, and just as importantly, what isn't.
✓ What's in the MathKnights shop
Avatar items — hats, weapons, pets, and other treasures — paid with coins your child earned solving math.
Castle upgrades — visual rewards that unlock as quests progress.
Retake credits — earned through play, or granted by you from the parent dashboard.
All items priced in coins earned through math — never bought with money.
✗ What's NOT in the MathKnights shop
"Buy 100 coins for $0.99" — no real-money coin purchases. Ever.
Loot boxes or surprise mechanics — every item shows its exact price; nothing is randomized.
Limited-time pressure sales — no countdown timers, no "this offer expires in 2:14."
Daily-login streaks designed to manipulate — your child can skip days with zero penalty.
Third-party ads, ever. Not for "kid-safe" toys, not for cereal, not for anything.
In-game buy buttons. Kids can't subscribe or buy anything from inside the game — only their parent can, from the dashboard.
Our pricing model, plainly
Parents pay one fair price (Premium Family — $59.99/year, about $5/month, or free Basic). Kids never pay anything. That's the whole business model. There is no second revenue stream from your child's screen time, and there will never be.
— Erika, founder. This isn't a marketing claim — the code literally has no "buy coins" endpoint to call.
