Revision Village charges one of your students 249 US dollars.
This costs your whole department 249 US dollars, and the pages mark the work.
Everything a student touches is free, with no sign-in and nothing stored.
That is not a trial and it does not expire. What a department licences is the
half that is built for teachers.
Free, permanently, for anyone
- Every interactive page. Drag the points on a scatter graph and watch
the regression line and r recompute live.
- Every investigation, including the ones that refuse to reveal anything
until the student commits an answer.
- The written notes and worked solutions, set out one step per line with
the equals signs aligned.
- The animations and the videos.
No login, no email wall, nothing stored about any
child. Send your students the link today if you want to.
See a student page (Applications and Interpretation SL,
correlation and regression).
What the licence adds
- The teacher side of every page. The answers, what each
specific wrong answer reveals about the student's thinking, where the
levels separate, and how long each part really takes.
- Assignable questions, seeded per student. Everyone in
the class gets the same difficulty with different numbers, so the work
is theirs.
- The class view. Which question your class got wrong,
what they typed instead, and whether they all made the same mistake or
different ones. Those two need opposite responses and nothing else
tells you which you are looking at.
- Printable versions for homework and for the days the
wifi is down.
- The right to run the pages behind your own school login.
A class that all gives the same wrong answer has
one idea to correct on Monday morning. A class that gives twelve different
wrong answers has a question that needs rewriting. Marking a pile of books
will not tell you which of those you have.
What it costs
$249 per unit, per department, per year
Up to six teachers and all of
their students.
| One unit | $249 a year. Start with whichever unit you teach next: Applications and Interpretation statistics, Analysis and Approaches calculus, or an MYP unit. |
|---|
| A full course | $690 a year, every unit as it is finished. |
|---|
| A single teacher | $49 a year, if your department will not move yet. |
|---|
Paid by invoice and bank transfer, which is how most schools prefer to buy
anyway. A card link is available if your finance office would rather. No
purchase order needed at this size in most schools, which is deliberate.

Who writes it
Keith Spencer. Head of Mathematics at an international school
in Bangkok, thirty years teaching US, UK and IB curricula. B.A. Mathematics, University of North Carolina Wilmington. Licensed
in North Carolina, Maryland and Connecticut.
Every page is used with my own classes before it is offered
to anyone else, which is the only reason the wrong answers are diagnosed
properly. You cannot write "you are one short, check the last upright" unless
you have watched twenty students do exactly that.
What this is not
- Not a revision subscription for students. They already have those, and
the free pages here are better used in a classroom than in a bedroom.
- Not official IB material, and nothing here reproduces syllabus or
criterion text. It is lesson material written by a head of department.
- Not a replacement for teaching. It marks, diagnoses and reports. You
still have to be in the room.
If you want to try it with one class before spending anything,
do. The student pages are free and need no arrangement with me at all. The
licence only matters once you want the marking and the class data, and that is
the right order to find out in.
