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.
- Every answer math-checked. A symbolic math engine independently verifies the math in the tutor's replies — not "we're careful," but checked, every time.
- 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 covers up to two students. 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.
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 — the classroom door is wide open.
- 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.
