Mr. Cadabra teaches every lesson out loud, one step at a time, starting from what a word even means — patient, honest, and always on call. And while he teaches, Mr. Cadabra's Classroom quietly builds the file a homeschool family actually needs: an honest instructional-hours log, mastery evidence from real quizzes, and a printable records report for your state, evaluator, or co-op.
77 seconds: what Mr. Cadabra's Classroom looks like for a homeschool family.
Every math program promises personalized learning. Here's the promise that matters on filing day: when it's time to show your work, the records already exist. While Mr. Cadabra teaches, the Classroom quietly builds the file your state, evaluator, or co-op wants to see.
One click from your parent view: an instructional-hours log, scored unit checks, mastery evidence, and dated awards — a running record of demonstrated skill, not just attendance. Print it for an evaluator, a co-op, or the filing drawer.
Every course page doubles as a scope & sequence — all nine units, printable for portfolios and curriculum filings. See the courses →
Engaged-time tracking gives you honest instructional minutes per day and per course — many states ask homeschoolers to keep exactly this, and ours counts real work only (more below).
Homeschool rules differ by state — Mr. Cadabra's Classroom gives you the records and the plan; you stay in charge of your state's specifics.
Mr. Cadabra's Classroom counts a minute only when the lesson tab is actually open and your student is actually doing something. Walk away, switch tabs, leave it running — the clock stops. So "2h 15m this week" means two hours and fifteen minutes of math, a number you can put in an instructional-hours log with a straight face.
Every dashboard shows it: today, this week, per course. (Sample data.)
Your free parent account (at mrcadabra.com/family) opens a read-only view of your student's real progress: what's mastered, what's slipping, and — most useful of all — "where to help next." No made-up numbers, no participation trophies: every score comes from an actual check your student took — advancing a topic takes a real 80%, mastering a unit takes 90%, and the bars never round up. When this dashboard says mastered, it's true.
Teaching more than one student? Each gets their own code, their own dashboard, and their own pace.
The parent view. (Shown with sample data.)
The student's own dashboard — the same honest data, made motivating. (Sample data.)
Your student sees the same truth you do: a nine-unit path through each course, units turning gold as they're mastered, a day streak to keep alive, and "strengthen next" suggestions that make the next step obvious. Progress they can see is progress they chase.
Every Friday: minutes of real work, units advanced, checks passed, new awards, and Mr. Cadabra's own written summary — the week's homeschool record, written for you. Lands every Friday, with one-click unsubscribe.

Maya's week with Mr. Cadabra's Classroom
This isn't a black box you hand your homeschool to. You set the direction; Mr. Cadabra supplies the patient, step-by-step teaching — and reports back to you.
From your parent account, pick the unit you want front and center and it becomes today's plan in the classroom. Your plan steers — and your student's own deliberate choice is still respected in the moment, so steering never turns into a cage.
Placement starts each student at the right unit — an older student can rebuild fractions without ever seeing a grade level on screen.
Use it as the math spine or alongside what you already love — practice mode coaches your student through any problem they bring.
You're right to ask them. Here are ours, answered plainly.
No. Mr. Cadabra teaches one step at a time and waits for your student's turn. Even a frustrated "just tell me" never gets a bare answer: after a genuine try, he works a problem on the board while explaining it — then immediately hands your student a similar one that's theirs.
As Mr. Cadabra teaches, a separate math engine re-computes his checkable claims before your student sees them — and every score is plain arithmetic, never a judgment call.
They talk with Mr. Cadabra back and forth; their speech is transcribed to text and the audio is deleted immediately — never stored. Need it quiet? Typing works any time, and the youngest students have big answer buttons beside the microphone. Parents & privacy →
Mr. Cadabra stays warmly on the math — he never pretends to be human and doesn't wander into chit-chat. If something bigger than math ever comes up, he responds with care in one short message and encourages your student to talk with you or another trusted adult.
The method behind the teaching: built on the What Works Clearinghouse practice guides where they exist (elementary math through algebra), and on professional standards — NCTM, MAA — for the courses above them.
One family plan covers ten complete courses, first grade through college — compare that to what a single hour with a private tutor costs where you live. Try a full lesson free, no card required. Founding families lock in introductory pricing and get a direct line to the builder.
Try a lesson free See pricingYes. Ten sequenced courses from first-grade math through college, a placement that finds the right starting unit, mastery quizzes with a real 90% bar, and a visible scope & sequence for every course. Or keep the curriculum you love and use Mr. Cadabra alongside it — Practice mode coaches your student through any problem they bring.
We give you the records states most commonly ask for: an instructional-hours log built from engaged time only, mastery evidence from real scored quizzes, and a printable scope & sequence and records report. States differ, and you stay in charge of your state's specifics — we hand you the paperwork, not legal advice.
A minute counts only when the lesson is open and your student is actually working. Walk away, switch tabs, leave it running — the clock stops. The number that lands in your log is one you can file with a straight face.
Each student gets their own login code, their own tutor memory, their own dashboard, and their own pace — all managed from one free parent account, where you can also rename a student or mint a fresh code. Plan details are on the pricing page.
Yes — from your parent account, pick the unit you want front and center and it becomes today's plan in the classroom. Your student's own deliberate choice is still respected in the moment, and their dashboard's "strengthen next" keeps the best next step obvious even when you don't steer.
The printable records report — hours log, quiz scores, mastery evidence, and awards — is one click from your parent view. Course pages double as a printable scope & sequence for portfolios and curriculum filings.
No. Placement starts them where they actually are, and no grade level ever appears on their screen — an older student can rebuild fractions with complete dignity. The tutor meets them there and builds up.
No — Mr. Cadabra does the teaching, out loud, one step at a time, starting from what a word even means. You get the window in: the parent view, the Friday email, and the list of recently tricky problems, so helping is easy when you want to lean in.
