Geometry for a kid who loves chess
chesscodingart
This is a real, playable sample of a Mathbloom Geometry course, built for a kid whose big thing is chess. Mathbloom generates each course around one child: their interests become the worked examples, word problems, and jokes, while the math underneath follows the standard Geometry sequence.
The sample has 8 interactive lessons, including "Points, Lines, Planes, and Angles", "Reasoning and Introduction to Proof", "Parallel and Perpendicular Lines". Chess is not a sticker on top; it shows up inside the lessons, in the scenarios, the practice problems, and the callouts, with coding and art woven in along the way. The thread that ties this sample together: The chessboard: an 8-by-8 grid that starts as a plane of points, lines, and angles in lesson 1, hides similar triangles in a scaled travel set by lesson 6, and returns one last time in the showcase as a board your child can now read like a proof.
To be clear about what you are looking at: this demo kid and their interests are fixed, so everyone plays the same sample. When you subscribe, your kid's course is generated fresh, on their name, their age, their real interests, and their pace. The sample below is free to play, with no sign-up.

From Algebra 1 to Calculus, the math gets abstract but the motivation does not have to. These samples anchor real course-level content, on real standards, in the things a teenager actually spends time on.
Questions parents ask
Is this a real course?
Yes. The 8 lessons in this sample are fully authored and playable in the same interactive player a subscriber's kid uses: teaching steps, checks you can retry, and mini-games. It is a demo in one sense only: the persona and interests are fixed. A generated course for your own kid runs up to 12 lessons and is written around them.
How does the personalization actually work?
You tell Mathbloom your kid's age, the math they need, and a few interests. The course is then generated fresh for them: the sequence of lessons follows real Geometry standards, while the examples, word problems, diagrams, and humor are built from their interests, with their name woven through. This page's sample shows what that looks like when the interest is chess.
What does it cost?
Playing this sample is free, no sign-up. A full membership is the Family plan at $49/mo for up to 3 kids, each with their own generated courses, with a 30-day money-back guarantee and cancel anytime. Tutors and co-ops can run up to 10 learners on Studio at $199/mo.
Is it aligned to grade level?
The sample follows the standard Geometry scope, and generated courses are built on real grade-level standards with named mastery objectives per lesson. A kid who is ahead or behind simply starts at the level that matches where they are, not their grade label.
