The Equation Files: Pre-Algebra That Makes Sense

Release date TBA, later in 2026 – follow the announcements!

Algebra a student can see, touch, and reason about

Somewhere in middle school, letters appear next to numbers — and for many students, this is the moment math stops making sense and starts being memorized. This course exists so that moment never happens.

And the stakes are real: working with equations is the core skill of mathematics from Grade 9 on. Functions, systems, quadratics, and every formula in physics and chemistry stand on it. A student who truly understands equations walks into high school math prepared; a student who memorized rules meets the same wall again, higher.

Instead of rules to memorize (“move it to the other side and flip the sign”), every move in this course is built on something visible: a balancing scale, a number street, a detective’s notebook. An equation is a claim; solving keeps the scale honest; and every answer must survive a check — because an unchecked answer is only a guess.

The student plays a detective. Equations are cases. The most common mistakes are not failures but named traps — met openly on screen, defeated, and even laughed at. From the first balanced scale to equations that lie — the whole story of equations, told so it makes sense.

What students learn

The course covers pre-algebra from the very first equation to equations with brackets and letters on both sides. Students learn to:

• read an equation as a claim on a balancing scale — and keep it balanced;
• work confidently with negative numbers, built from scratch inside the course;
• solve one-step, two-step, and multi-step equations;
• translate word problems into equations — and answer the question that was actually asked;
• check every answer against the original claim;
• recognize equations with no solution, or true for every number — and prove which is which;
• solve by understanding, not by guessing.

Who this course is for

Ages 11–15 · Grades 6–9

The course suits students meeting equations for the first time, and students who already met them at school but solve by half-remembered rules, lose marks to sign errors, or skip checking.

Students only need basic arithmetic. Negative numbers are not required — the course builds them from the ground up.

Parents do not need to teach anything. Students watch the videos and complete the work independently — though the family is warmly invited to be the audience when the course asks the student to explain a solved case out loud.

What is included

• 15 animated video lessons, about 10 minutes each;
• 15 self-check quizzes — the course’s practice track, with friendly, teaching feedback;
• 14 printable play sheets with answer keys — one after each of Lessons 1–14, so every lesson ends on paper (Lesson 15 ends with the Graduation Sheet below);
• 4 written detective missions — full cases in which the reasoning is the work, each with a complete answer key and marking guide;
• a 10-question Graduation Quiz that climbs from Lesson 1 to Lesson 15 and shows exactly which lessons deserve another visit;
• the Graduation Sheet — a keepsake with the course’s sixteen laws and a teach-it-to-your-family ceremony;
• a printable certificate of completion.

Practice without fear

Practice lives in the quizzes: immediate, friendly, and repeatable. Wrong answers teach — each one explains the trap it came from. The Graduation Quiz at the end climbs the whole course and shows exactly which lessons deserve another visit.

The four missions are the creative track: optional, rich cases for students who want more than practice — writing full solution pages, judging suspects at a trial, spotting planted errors, and inventing equations and stories of their own. Students are never ranked or compared with anyone else. The only comparison in this course is with yesterday’s detective.

Optional personal feedback

The standard course is complete on its own: practice and progress live in the auto-checked quizzes, and every mission includes a full answer key and marking guide for checking at home.

Families may also choose the course with mission review: the student submits the four detective missions, and the teacher personally responds to each one with written comments — what was done well, which trap nearly caught them, and what to try next.

The review option is for one student and remains available for six months after enrolment.

Course access and sibling accounts

Once purchased, the course remains available for as long as it is hosted online. Students may pause, return later, and repeat any lesson.

Each student receives an individual account, progress record, and certificate.

After one student enrols, additional students from the same immediate family may receive their own course account at 90% off the regular course price.

Founding-family price

Available for the first two weeks after the course goes active. Follow the announcements!

Course with four personally reviewed missions: add the Mission Review Add-on 

The missions ask for substantial written work — full solution pages, checks, and explanations in the student’s own words — and each submission receives an equally careful written response. The review price reflects this individual, line-by-line reading of your student’s reasoning.

Try the first lesson free

Lesson 1 is available free of charge. Your student can watch the complete lesson and take its self-check before you decide whether to enrol.
