Math.Foundation traces mistakes back to missing prerequisites. Ada Tutor repairs the gap, then the learner proves mastery before moving on.
No signup required to try the diagnosis. Built first for Years 4–9, with prerequisites traced back to Foundation and extension through Year 10.
Try the diagnosis
Choose the answer a learner might give. Math.Foundation uses the shape of the mistake to decide what prerequisite needs repair.
A worked product interaction — no account required.
Choose an answer to see the prerequisite diagnosis.
Instead of repeating the same question, Math.Foundation traces the error backward through the skill graph and chooses the smallest useful repair.
Families need to know why one learner is stuck. Schools need to know which prerequisite gaps are distributed across a class.
Start with a free diagnostic interaction, then follow one learner's skill graph through targeted repair and spaced review.
See prerequisite gaps across the class, group learners by repair need, and run a measurable intervention pilot rather than another generic practice program.
Worked evidence example
Math.Foundation is designed to leave an evidence trail from the first mistake to a fresh mastery check. This example uses representative demo-model data, not a live student's record.
Before
The learner completes only the ones row. The answer is wrong, but the shape of the error is useful.
Observed responseDiagnose
Ada tags the misconception and traces it to the prerequisite: applying place value inside two-digit multiplication.
Misconception → prerequisiteRepair
The repair makes the place-value structure explicit: 12 × 10, then 12 × 3, then combine.
Targeted prerequisite lessonFresh check
A different question checks whether the repaired method transfers. The learner can also be asked to explain the decomposition.
Illustrative mastery evidenceMath Foundation is a mathematics learning, diagnostic/intervention, and mastery platform that maps mathematics as a dependency graph, diagnoses the misconception behind wrong answers, repairs prerequisite gaps, and uses mastery gates before learners advance. Ada Tutor may support selected tutoring interactions as a component; it is not the product category.
For families, tutors, homeschool learners, and adults who want personalized math learning with unlimited tutoring and spaced review.
For teachers and schools that need a classroom math gap heatmap, roster-based intervention groups, and evidence of repaired prerequisite skills.
The product combines structured curriculum, Ada Tutor, misconception diagnosis, mastery evidence, and parent or teacher dashboards instead of acting like a generic chatbot or worksheet app.
Traditional classrooms move on when the calendar says so, not when you're ready. One missed concept in grade 4 becomes "I'm not a math person" by grade 9. Math Foundation never moves on until the foundation holds.
Every concept in mathematics, mapped as a dependency graph of atomic skills. You always know exactly what you've mastered, what's next, and why.
A patient voice tutor powered by Ada Tutor explains, listens, and re-explains differently — Socratic when you're close, direct when you're stuck. Available every hour you are.
You don't pass with 70%. A skill is mastered when you can do it reliably, explain it, and apply it — then we keep it alive with spaced review.
Wherever you start — age 5 or 50 — a diagnostic places you on the graph, and the path adapts around your gaps. Here's a tiny slice of it.
A 9-node slice of the full graph. The alpha graph now includes 600 authored skill briefs across 60 clusters, expanded into 2,400 generated atomic learning units.
A conversational diagnostic finds your true frontier — often surprising. Adults routinely discover gaps from decades ago that explain everything.
Your tutor teaches the skill aloud, checks understanding with questions, and watches you work. Wrong answers aren't failures — they're diagnostic data.
Demonstrate mastery to unlock the next skill. Spaced reviews resurface old skills at exactly the right interval so the foundation never erodes.
Math Foundation handles learner data like school infrastructure, not a social product. Permissions, exports, and privacy expectations are part of the product surface.
No public student profiles. Learner work stays inside family, teacher, or school-managed contexts.
Families can manage learner profiles, progress visibility, and review routines from one account.
Classroom views are scoped for teachers and school leaders, with roster and rollout boundaries.
Pilot packets and learner evidence can be exported for school review, reporting, and handoff.
Procurement, privacy, and onboarding details are captured for Australian school rollout support.
The interface is designed for keyboard access, readable contrast, responsive layouts, and reduced motion.
Use the pack for principal, curriculum, wellbeing, procurement, and privacy conversations. It collects the one-page overview, pricing, implementation timeline, privacy summary, AI safety summary, sample pilot report, and contact path.
Free to start. Affordable to master. Classroom and school bundles scale the same mastery graph without per-teacher setup pain.

Stripe sends the official receipt. Math Foundation uses this email to activate the learner, family, or classroom setup path in the app at app.math.foundation.
School intervention pilot
Start with one bounded cohort of up to 30 learners for six instructional weeks, preceded by Week 0 setup and followed by one close-out review. Establish the baseline, group learners by prerequisite gap, run targeted repair cycles, then finish with evidence the school can inspect.
Use the same mastery graph and reporting model for a classroom, grade team, or whole-school rollout.
For one teacher or intervention lead proving the diagnosis → repair → verification model with a bounded cohort.
For a year level, department, or multi-class intervention rollout.
For schools that want one mastery progression across grades and support programs.
It is built first for Years 4–9 learners who are falling behind or losing confidence in maths, and for the teachers running numeracy intervention with them. The skill graph runs from Foundation through Year 10, so it can trace a Year 8 learner's gap back to a Year 3 prerequisite and repair it there. Homeschool families, tutors and adult learners can use the same graph — the diagnostic places you where you actually are, with no grade labels — but the product is designed and evidenced around the Years 4–9 case first.
Two things. First, the mastery gate is real: you cannot advance past a skill you haven't proven on questions you've never seen, so gaps can't silently accumulate. Second, the tutor diagnoses your specific mistake — answer 35 to 42 − 17 and it recognises the classic column-subtraction bug and re-teaches that, rather than just flashing "incorrect, try again."
Explorer is free forever: full diagnostic, skill graph placement, three tutored lessons a week, and unlimited self-paced practice. Foundation is $19 AUD/month for unlimited Ada Tutor voice tutoring and spaced reviews. Family covers six learners for $49 AUD/month. Classroom bundles start at 30 seats, grade-team bundles at 150 seats, and school bundles at 500+ seats.
No — it makes them work better. Classrooms have to move at one speed; Math Foundation repairs and reinforces at yours, then hands teachers a live map of every student's gaps so class time goes where it's needed. Many of our design choices come from teachers, and the educator dashboard is built for them.
The current alpha graph exposes 600 authored skill briefs across 60 clusters and 2,400 generated atomic learning units: concept, worked example, application, and mastery gate for every skill. The live demo shows a 17-skill slice, while later credential pathways and summative certificates remain roadmap work.
The public site and lesson demo are live; deeper school and credential surfaces remain clearly marked as alpha or roadmap.
Start small with one learner or one classroom, or prepare a grade-team rollout with pricing, procurement details, and onboarding support in one place.
