Mathematics academy • School LMS
Every course, grades 9 to 12.
Every course, grades 9 to 12.
With a real classroom behind it.
The full California sequence is mapped — both pathways, honors and AP — from Algebra 1 and Integrated Math I through Calculus BC, Statistics and Data Science. Practice is generated fresh every time and marked algebraically rather than by string match, so any equivalent form earns the credit. Wrapped in a complete classroom system with assignments, rubric grading and gradebooks, plus a stock-market programme that runs as an extracurricular.
- Database-enforced permissions, not hidden buttons
- Virtual money only — never connected to a brokerage
- Runs entirely on free tiers
- Written lessons cover Algebra 1 so far — the rest of the catalogue is sequenced and practisable, not yet narrated
Three dashboards, one gradebook
Every permission is enforced in PostgreSQL with Row Level Security — so what a student cannot see, a student genuinely cannot fetch.
◆
Teachers
Only the classes you are authorized to teach — nothing else.
- Assignments with rubrics, late policy and resubmissions
- Target the whole class or individual students
- Rubric grading, private feedback, bulk release
- Gradebook with CSV export and missing-work tracking
◆
Administrators
Roster control, approvals and an immutable audit trail.
- Approve registrations, invite teachers
- Create classes, assign teachers, enroll and transfer
- Deactivate accounts without deleting records
- School-wide reports and audit logs
15 courses, 102 units, 459 lessons
Because California's 2023 framework says the traditional and integrated pathways cover the same standards in a different order, lessons live in one shared pool and each course is an ordered playlist over it. Writing a lesson once makes it appear everywhere it belongs.
◆
Both pathways
Whichever sequence your district runs.
- Algebra 1 → Geometry → Algebra 2
- Integrated Math I → II → III
- Honors as a depth flag, not a duplicate course
- 178 standards tagged across the catalogue
◆
Fourth year and AP
The full senior-year fan-out.
- Precalculus, AP Precalculus
- AP Calculus AB and BC
- AP Statistics, Data Science
- Discrete Mathematics, Financial Algebra

Practice that cannot be memorised
30 generators, new numbers every attempt.
- Marked algebraically —
1/2,0.5and2^-1all count - Equations match up to scale:
2x = 4≡x = 2 - Step-by-step worked solutions on every item
- Rendered as native MathML, no CDN
Where the writing has reached. All 459 lessons have a title, a place
in the sequence and their unit's standards. 53 of them have a written explanation today,
with Algebra 1 complete end to end. Every other lesson page says so on its face rather
than pretending — see what's unfinished.
Extracurricular: the stock market programme
Six levels, beginner to advanced, kept complete and assignable by teachers. Every lesson here has a plain-English explanation, an analogy, key terms, an interactive exercise and a five-question quiz that explains both right and wrong answers.
Education only. This platform does not provide investment advice, does not
promise profits, and never connects to a real brokerage. Risk management is taught as a
core subject, not an afterthought.
Built for a classroom, not a demo reel
📈 Charts that teach
Candlesticks with 9/20 EMA, 50/200 SMA, VWAP, Bollinger Bands, RSI, MACD and relative volume — each explained in the curriculum, including when it misleads.
🧮 Eight working calculators
Position size, risk-to-reward, P&L, percentage change, fees, win rate, expectancy and compounding — each with input validation and a plain-English reading of the result.
📝 Assignment types that fit the subject
Quizzes, chart analysis, candlestick ID, support/resistance, position sizing, R:R drills, psychology reflections, paper-trading challenges, journal reviews and research projects.
🔒 Private by construction
Students cannot read another student's submission, grade or journal — even by guessing a URL or calling the API directly. Verified by 127 automated policy tests.
🧾 Honest market data
Prices are clearly labelled synthetic, historical, delayed or live. With no feed configured, the simulator uses deterministic generated candles and never fabricates real quotes.
💸 $0 running cost
Supabase free tier plus a free static host. No build step, no server to pay for, no market-data subscription.
Security you can actually check
Student records and grades deserve real protection. Authorization lives in the database, so bypassing the interface changes nothing.
- Row Level Security on all 21 tables
- Role, school membership, class enrollment and teacher-to-class authorization
- Role changes blocked by a database trigger and written to an audit log
- Quiz answer keys unreadable by students; graded quizzes scored server-side
- No service-role key, password or privileged secret in any front-end file
