Everything, on one page
What makes Mr. Cadabra different.
Not a video library. Not a worksheet machine. A patient, one-on-one teacher
who talks, draws, checks his own math, proves mastery, and keeps parents in the loop —
every feature below is live in the classroom today.

The teaching11 features▶
A real lesson with a real teacher — tireless, endlessly patient, available whenever your student is.
- A tutor who actually talks. Mr. Cadabra teaches out loud in a warm human voice — and your student talks right back, a real spoken back-and-forth, like sitting beside a tutor. (Typing works any time, and the youngest students get answer buttons too.)
- A live whiteboard. He draws every step as he explains it — equations, number lines, shapes, graphs — and the board never runs ahead of the student. See it, hear it, work it.
- Foundation first, one-on-one. He doesn't lecture and he doesn't hand over answers. He asks the next right question, lets your student do the thinking, and steps in exactly when they need him.
- Help that never dead-ends. Miss once — a hint. Miss again — a different explanation with the steps worked on the board. Still stuck? He shows the way warmly and moves forward. Struggle is normal here; being abandoned isn't.
- Lessons tailored in real time. Pacing, examples, and encouragement adapt to the student in front of him — including per-topic playbooks for the classic misconceptions kids actually have.
- Built for every age. The youngest students say their answers out loud — no typing or reading fluency needed — with big answer buttons beside the microphone. Older students talk too (or type) and get graph paper the tutor can teach them to use.
- Bring him any problem. Stuck on tonight's homework? Practice mode takes the exact problem from school and works it out together, step by step — without just doing it for them.
- Explore any topic. Curious about one thing? Pick any topic from any unit and talk it through — no schedule, no pressure, just a patient teacher and a whiteboard.
- A tutor who remembers you. Mr. Cadabra picks up right where you left off — what clicked, what was tricky, what's mastered — every session, automatically. No re-explaining, no starting over.
- A real refresher after time away. Gone a day or more? The next session opens with a friendly catch-up on where things stand — a memory jog from a friend, never a pop quiz.
- Fluency sprints. Short, timed rounds of quick math facts for every course, offered at the start of a lesson — race your own best and watch the facts become automatic.
Your starting point & your plan5 features▶
Ten complete courses on one ladder — and an assessment that finds exactly where your student belongs on it.
- An entry assessment that builds a personal plan. A friendly placement maps strengths and weaknesses across the whole course, then builds a plan tailored to your student — the right starting unit, the right focus. No one sits through what they already know, or drowns in what they don't.
- Pause it, finish it later. Life happens — a placement assessment saves as your student goes and picks up right where they stopped, so it never has to be one sitting.
- A curriculum you can see. Every course is laid out unit by unit, topic by topic, right in the classroom. Students always know where they are and what's next — no mystery meat.
- Retake any Unit Quiz. A rough day doesn't get the last word — when a student is ready, they can walk back in and retake the quiz, and their best real score is the one that counts.
- Ten courses, grades 1 to college. Entry-Level Math through Basic Math, Pre-Algebra, Algebra I & II, Geometry, Trig/Pre-Calc, Probability & Statistics, Calculus, and Differential Equations — one tutor, the whole journey.
Proof, not promises10 features▶
Anyone can say "your student is doing great." We built the machinery to prove it — and to catch our own mistakes.
- Math that is checked, not trusted. Every answer in the written lessons is computed by code, never typed by hand. When the tutor works something out live, a symbolic math engine re-computes the answers it gives and the equations it draws before your student sees them — a reply with wrong math is rewritten, and never sent if it can't be put right.
- Immediate, specific feedback. Right or wrong, your student hears exactly what was right and what to fix, in the moment — the kind of feedback that builds real confidence instead of empty praise.
- Two-tier quizzes. Topic quizzes (80% to advance) checkpoint progress inside every unit, and the Unit Quiz demands 90% for mastery. Progress here is earned, and it sticks between sessions.
- The tricky ones come back. Problems missed on a quiz aren't forgotten — the tutor remembers them and brings one back a little later, right when a second look does the most good.
- A dashboard that never lies. Units mastered, accuracy, streaks, engaged time — nothing is ever invented or inflated. If a number is on the screen, it happened. Empty means empty.
- Awards that mean something. Trophies for mastery, medals for effort and streaks — earned awards never vanish — and the Graduate honor when a whole course is truly finished.
- Honest time tracking. The clock counts engaged, working minutes only — idle time never pads the numbers. What you see is real learning time.
- "How am I doing?" — one click. At any moment, a student can tap one button and see their whole picture — units mastered, accuracy, streaks, awards. Nobody here ever wonders where they stand.
- Progress that sticks. Mastery, quiz results, and awards are saved automatically and follow the student — sign in with the same code on any device and everything is right where they left it.
- Streaks build the habit. Day streaks and effort milestones reward showing up, not just being right — and once a streak medal is earned, it never expires. Momentum you can see.
For parents6 features▶
You stay in the loop without hovering — and the paperwork takes care of itself.
- A weekly email that speaks parent. Every Friday: what your student worked on, how much real time they put in, where they shone, and where they struggled — written in plain language, not data dumps. One-click unsubscribe, always.
- Steer the pace when you want to. From your account, pick the unit you'd like your student centered on and it becomes today's plan in the classroom — while a student's own deliberate choice is always respected. Guidance, not remote control.
- See what was tricky. The same recently-missed problems the tutor is reviewing show up in your view and in the Friday email — so "how can I help?" finally has a specific answer.
- Printable homeschool records. Download and print a clean report — hours log, mastery evidence, quiz scores, awards — ready for state homeschool filing or your own records.
- One family account. Add each student with just a first name or nickname; each gets their own login code, tutor, and dashboard. One plan per student, at one price. You see everything, read-only.
- Everything managed in one place. Rename a student, mint them a fresh login code, or remove a student — right from your account, with deliberate confirmations so nothing happens by accident. And if you ever leave, one step deletes your account and every student's data, with billing canceled first.
For teachers & co-ops3 features▶
Follow a whole class without new logins, new software, or new headaches.
- Classrooms in one code. Gather your students under a simple class code — no accounts to build, no passwords to reset — and watch the whole group at once.
- The class heatmap. One glance shows every student against every unit — who's strong, who's stuck, and exactly where to spend your attention tomorrow.
- Read-only student views. Open any student's honest dashboard — the same real numbers their parents see. Look, don't touch: teachers and parents can never alter a student's work.
Community & trust6 features▶
Built from day one for other people's students — the highest bar there is.
- Privacy by design. Voice audio never stored. When your student talks with the tutor, their speech becomes text and the audio is deleted immediately — no recordings, ever. First names or nicknames only — we ask for less data, not more. Analytics are cookieless. Your student is a student here, not a product.
- A parent community. A moderated forum where families share what's working, trade ideas and resources, and shape which courses come next.
- Try everything first. A full interactive demo lesson — voice, whiteboard, real teaching — with no account and no card. Meet Mr. Cadabra before you tell him your name.
- A real lesson on a phone. On small screens the whiteboard comes first and the mic docks at the bottom of the screen — the whole classroom fits in a back pocket.
- Built to include everyone. Screen-reader labels, keyboard-friendly dialogs, and reduced-motion support are built in.
- Help written for kids. A plain-language help page answers the questions students actually ask, and shows the support address in words a kid can read to a grown-up — no dead-end links.
