For teachers

Free for your classroom. No accounts, no student data.

Lessons, study guides and formula sheets for BC, Alberta and Ontario courses, built to be set with one link and photocopied without asking.

Classroom use. Teachers, tutors and parents may print and photocopy the booklets, formula sheets and study guides, whole or by the page, for their own students, free. Please keep the formula.expert line on each page. The terms →

Your course

Each course names the provincial courses it fits. On its page, pick yours under “I follow” and students see your course’s modules in order.

University courses (fluids, mechanics, process water and more) are in the Exam Room too.

Set work with one link

Copy a lesson’s address into your class page. Students open it on a phone or a Chromebook, with nothing to install.

  • New numbers on every attempt, so answers can’t be passed around.
  • A dare link sets a score for the class to beat.
  • The skill check starts each student at their own level.

A warm-up every day

Put today’s formula on the projector: one formula, tied to the date, with a worked example to try. Mole Day gets Avogadro, Pi Day gets π.

Show it live

Drag a tangent along a curve, fill the area under one, walk water across the steam dome: the interactive charts read well on a projector.

What we don’t do

  • No student accounts, emails or names.
  • No marks sent to you, to us or to anyone else.
  • Progress stays on each student’s own device. They can show you their report card.
  • Visits are counted anonymously, to the city. Privacy

Tell us what your class needs

A missing formula, a course we don’t cover yet, or a number that looks wrong: one message and it goes on the list.
