Meet Professor Triangle — the math tutor who talks with your child, and writes to you every night.

A patient, always-available tutor who teaches out loud at a chalkboard, uses only questions aligned to Florida B.E.S.T., and sends you a plain-English report on how your knight is doing. For a fraction of what tutoring costs.

Every parent knows the moment: homework is out, your child is stuck, and you’re trying to remember how you were taught to compare fractions thirty years ago. A good tutor fixes that — but a good tutor costs $40 or more an hour, works on their schedule, and tells you very little about what actually happened in the session. We built Professor Triangle to change all three.

Professor Triangle is a tutor your child can talk to, who teaches from questions matched to Florida’s standards, and who tells you exactly how it went — every single day.

What a lesson looks likeA real conversation at a real chalkboard

Your knight taps “Talk to Your Tutor” in the game and steps into the Professor’s classroom. He greets them by name, remembers what they worked on last time, and offers a few lessons to choose from — all picked for them.

The Professor offers lessons picked from what your child is working on, what needs practice, and what comes next in the school year.

He explains it out loud

The Professor speaks in a warm, clear voice and draws on the board as he goes. Your child can answer by talking into the microphone or by typing — whichever feels natural.

Your child does the work

He puts a real question on the board — tap the answer, drag the clock hands, place the fraction on the number line, measure with the ruler. Kids learn by doing, not by watching.

A miss becomes the lesson

Wrong answer? He doesn’t just show the right one. He explains what went wrong and says “try again on the board.” After two tries he walks through it step by step, so your child always leaves understanding it.

He remembers

The Professor keeps a notebook on every knight — what clicked, what’s still shaky — so the next lesson starts where this one left off.

Good try! 3/8 has a bigger number on top than 1/4 — but look at 5/8. Same-sized pieces, and it has more of them. Try again on the board!

When your child misses, the Professor explains why — then hands the board back so they can get it right themselves.

Where the math comes fromThe AI does the talking. The math comes from a checked question bank.

Here’s the part most “AI tutors” won’t tell you: chatbots can make up math problems — and sometimes get them wrong. Professor Triangle doesn’t invent the math. Every question he teaches with comes from the MathKnights question bank, the same bank that powers our quests:

explains, encourages, and walks through mistakes

That split is on purpose. The game decides what to practice from data it trusts; the Professor decides how to explain it to your child. You get the patience and warmth of a tutor with the reliability of a curriculum.

How he knows where to startHe learns your child before he teaches them

A tutor who starts in the wrong place wastes everyone’s time. Professor Triangle uses three sources to figure out exactly where your knight is:

🧭
The placement check

A friendly 20–30 minute check-in across the grade’s skills. It isn’t a test your child can fail — it just finds where they are, so lesson one is already the right lesson.

⚔️
Quests they complete

Skipped the placement check? No problem. Every quest your knight plays shows which skills are solid and which need help, and the Professor reads that.

🗺️
Skill practice

Practice on the skill map and past lessons all feed his notebook, so the picture of your child gets sharper every day.

The placement check finds your child’s starting point — and they can pause and finish it later.

Then he picks lessons in this order

  1. What they’re still working on — skills from his notebook that haven’t clicked yet.
  2. Their weakest skills, weakest first — where a little help makes the biggest difference.
  3. What comes next in the school year — new skills in Florida B.E.S.T. order, mixing subjects so it stays interesting.

Maya: 3/8 because 8 is bigger.

The money questionHow families can save thousands on tutoring

Tutoring is one of the biggest education costs a family takes on. Here’s what one school year typically looks like for one child:

OptionTypical cost per school year
Private math tutor2 sessions a week at about $40/hour, 36 weeks≈ $2,880
Learning center (e.g. Mathnasium)Monthly membership plus enrollment fee — see our breakdown$2,500–$4,000
MathKnights Premium Family with Professor TriangleUnlimited lessons, any day, any time — and up to 4 kids$59.99
$2,400+

saved per child, per year compared with a private tutor or learning center — and with two or three kids, the difference multiplies. Premium covers up to four knights on one plan.

And it isn’t only about price. A tutor comes twice a week; the Professor is there on Tuesday night before the quiz, on Saturday morning, and over winter break. There’s no driving, no scheduling, and no waiting room.

An honest note from us: Professor Triangle is an AI, not a person, and we won’t pretend otherwise. Some children need a specialist, and if your child has a diagnosed learning difference, keep the experts in the loop. But for the everyday work — practicing, getting unstuck, building confidence — he’s patient, always on time, and he never has a bad day. And because you can read every word of every lesson, you’re always the one in charge.

Questions parents ask

Is Professor Triangle a real person?

No — he’s an AI tutor built into MathKnights. He talks with your child out loud, but the skills, questions, and pictures come from our question bank, not from the AI. You can read the full transcript of every lesson.

Are the questions really aligned to Florida B.E.S.T.?

Yes. Every question in our 13,000+ question bank is tagged to a Florida B.E.S.T. math benchmark for grades 1–5, and we audit the bank so each one sits under the right benchmark.

How does he know what my child needs?

A 20–30 minute placement check shows where your child is. If they skip it, he uses their recent quests and skill practice. Then he starts with what they’re working on, then their weakest skills, then the next new skills in Florida’s school-year order.

What will I receive as a parent?

On days your child has a lesson, an evening email with the Professor’s note, time spent, questions right, skill progress, and a try-at-home idea. The parent portal keeps every lesson transcript for 90 days. You can turn the email off anytime.

How much does it cost?

Every family can try 3 lessons free. Premium Family gives unlimited lessons for up to 4 children for $59.99 a year, or $9.99 a month.

Does my child need a microphone?

It’s more fun with one, but no — your child can type instead. The Professor always speaks out loud and writes on the board.

Is it safe for kids?

Kids sign in with a 4-digit PIN, never your password. There are no ads and no in-game purchases, and every word of every lesson is visible to you in the parent portal.
