Math Ladder AI · Personalized, mastery-based math

Every rung of the ladder - Kindergarten to 12th grade,
competitions, and major standardized tests.

A quick adaptive placement - usually about 15 questions, continuing up to 40 only when a strong run has not yet found your child's ceiling - maps your child onto a prerequisite knowledge graph, then the engine serves exactly the right lesson, review, or quiz at exactly the right moment - mastery learning plus spaced repetition across the whole K-12 span. Not a single track: from counting in Kindergarten through Algebra, Geometry, Precalculus and AP Calculus - with the full competition ladder and score-projected SAT/ACT and AP mock exams built in, both halves: the math sections and the reading and writing sections of the same tests.

One subscription. The whole K-12 ladder - not a slice of it.

Most adaptive math platforms teach a single linear sequence and stop there. Math Ladder AI covers the same core rigor and the parts families actually need next to it - every AP math course, a real competition ladder, and the college-entrance tests students actually sit - for a fraction of the usual price.

✓ Kindergarten → 12th grade - counting and place value all the way through Algebra, Geometry, Precalculus, and the full high-school sequence.

✓ Every AP math - AP Precalculus, Calculus AB, Calculus BC, and Statistics, each with timed multiple-choice sections and rubric-scored free response.

✓ A full competition ladder - Math Kangaroo (6 levels), MOEMS, MATHCOUNTS, Noetic, Purple Comet, and AMC 8 · AMC 10 · AMC 12 · AIME - each with timed contest mocks.

✓ College-entrance test prep - PSAT, SAT, and ACT math, with timed sections and honest score projections.

✓ And the English half of those tests - SAT, PSAT and PSAT 8/9 Reading & Writing in the real two-stage adaptive format, plus ACT English and ACT Reading, full length and on the clock.

$12.99/month - unlimited, procedurally-generated practice, personalized to every learner, at a fraction of what comparable adaptive platforms charge. Free during our Founding Family beta - no card required.

Knowledge graph

Every topic is linked to its prerequisites. You only see a lesson when you're ready for it, and never repeat what you already know.

Spaced repetition

Reviews are scheduled on expanding intervals - and practicing advanced topics ripples review credit down to the fundamentals underneath them, which reduces redundant review.

Rungs & streaks

One rung ≈ one minute of focused work. Set a daily goal, keep the streak alive, and watch the course fill in.

Built by a professor - not a growth team

Math Ladder AI is designed by its founder - a PhD and Full Professor of Computer Engineering and an internationally recognized researcher with 25 years of university-level teaching experience. The mastery model, prerequisite knowledge graph, and spaced-repetition engine here draw on mastery learning, retrieval practice, and interleaving - brought to K-12, from Kindergarten counting up through AP Calculus. He used AI as his engineering partner to design and code the expert system, and live AI powers the built-in coach and homework help when a student gets stuck.

Real proofs, not just answers

Beyond numeric drill: arrange scrambled steps into a valid proof, and name the theorem or property that justifies each step - the reasoning skills an answer-only trainer can't reach.

Symbolic answers

Type answers the way you'd write them: pi/6, 2sqrt(3), 3x^2 + sin(2x). Grading is by mathematical equivalence, not string match.

Score-projected mock exams

Timed sections at real exam pacing - calculator and no-calculator - with multi-part free response on official-style rubrics and a projected score, for the AP, SAT, and ACT you're aiming at.

📖 A test score is both halves

Nobody applies to college with a math score. The reading and writing sections of the same exams are here too, full length and on the clock, with the same score projections and the same breakdown of where the marks went.

✓ SAT Reading & Writing - 54 questions, 64 minutes, in the real two-stage adaptive format: how you do on the first module decides which second module you get. Same for PSAT/NMSQT and PSAT 8/9.

✓ ACT English (50 questions, 35 minutes) and ACT Reading (36 questions, 40 minutes), each at the real section length and pace.

Every sitting draws fresh passages and questions, so a second attempt is a new test rather than a memory check. See what the English sections cost →

Live AI help when stuck

The built-in coach explains the why behind any step in plain language, and Snap & Solve reads a photo of a hard homework problem and walks through the idea. The engine decides what to learn; live AI helps through the rough spots.

Mistake Notebook

Every definitive miss is filed, re-taught, redone, and finally sealed with a fresh problem days later - mistakes are the curriculum, not red ink.

Paper counts too

Print worksheets with the answer key on its own page - then check the finished sheet online to earn Rungs for offline work. Great for car rides, co-ops, and screen-free days.
