Start with your child's grade

Each grade has three printable books, three companion apps and a curriculum guide.

Or read the year first — each guide explains what Ontario expects, in plain words, with the official expectation codes.

What’s inside

The same material three ways — a book to print, an app to play, a guide to read — because a child at the kitchen table, a child on a tablet, and an adult decoding a report card all need something different. Plus EQAO preparation, and free classroom tools.

Printable books

Thirty books, laid out for US Letter and ready to print — one idea per page, answer keys at the back with the reason and the expectation code. Maths, language, science, social studies, health, French and the arts.

Practice apps

Every book has a companion app that practises the same pages. No timers, no losing, no game over. A wrong answer costs nothing and “Show me” appears after two tries. Stars only ever go up.

Curriculum guides

One per grade, in plain words, with the official expectation codes so you can always find your way back to the source. What is new this year, where children reliably get stuck, and what actually helps at home.

Classroom tools

Whose Turn? is a name wheel that gives everyone a turn before anyone repeats. Saved lists, a project mode for the whiteboard, and every name stays on your own device — the wheel never uploads a name anywhere.

EQAO preparation

Grade 3 and Grade 6, in the assessment's own question formats — including the on-screen studio, because the real assessment is adaptive and digital, and paper-only practice quietly loses marks.

Perfectly aligned with the latest Ontario Curriculum

Most free worksheets claim curriculum alignment and never say how they know. This is what “aligned” actually means here.

  • Every mathematics expectation in every grade is covered in both the book and the app, tagged with its official code.
  • Language, Health, French and the Arts were read against the Ministry PDFs expectation by expectation, and the errors that audit found were corrected.
  • Each book ends with a verification page stating what was checked and what was not. Nothing claims more certainty than it has.
  • Canadian spelling, Ontario codes — B1.1, C2.3 — so a teacher's words and these pages match.

A worked example

An audit of the arts strand found that Grade 4 and Grade 5 had their principle of design swapped, and that two grades were told their focus “could not be confirmed”. The Ministry document names all eight plainly. Grade 4 is emphasis, Grade 5 is proportion, Grade 7 is unity and harmony, Grade 8 is movement.

All of it was corrected across the books, the apps and the guides — and the correction is written down in each affected file rather than quietly patched.

For teachers, schools and boards

Everything a procurement or privacy review usually asks, answered before you ask it.

Use it freely

What is collected

No accounts, no email addresses. Google Analytics counts visits — pages viewed, browser type, approximate location — and Google is the only third party a page talks to. A child’s answers and progress live in that browser, on that device, and never travel.

Built to be accessible

Larger-text and reduce-movement switches in every app, keyboard focus everywhere, screen-reader announcements on every answer, and no page that needs colour to be understood.

Classroom notes →

It survives your firewall

Every app is a single-page app and every book a printable PDF, each in one self-contained file. Copy it to a USB stick, a shared drive or an email attachment and it still works — with no internet connection at all.

Questions people actually ask

Is it really free? What is the catch?

It is genuinely free, and there is no catch. No account, no trial, no upsell, no advertising, and nothing is sold — not the materials, and not data about visitors. It was built for one child and shared because it may as well be useful to somebody else's.

Does this follow the actual Ontario curriculum?

Yes, and the material says exactly how it knows. Mathematics is covered expectation by expectation with official codes. Language, Health, French and the Arts have been read against the Ministry PDFs directly. Where something has only been checked at strand level, the page says so rather than implying more.

These are original plain-language materials, not official ministry publications, and are not endorsed by the Ministry of Education or by EQAO.

Which grades and subjects are covered?

Grades 1 to 8, covering mathematics, language, science and technology, social studies (history and geography in Grades 7–8), health and physical education, French, and the arts — plus EQAO preparation for Grades 3 and 6.

Do I need to install anything, or sign in?

Neither. Every app is a single-page app and every book a printable PDF — both open in any modern browser by double-clicking them. There is nothing to install, no account to create, and no email address to hand over.

Can my child use this on a tablet or phone?

The apps are designed for touch and work well on a tablet or phone. The printable books are laid out as fixed 8.5 × 11 inch pages, so they are best previewed on a larger screen — or simply printed, which is what they are for.

What is EQAO, and how does this help?

EQAO is Ontario's provincial assessment, written in Grade 3 and Grade 6. The materials here practise the same question formats, and because the real assessment is now digital and adaptive, there is an on-screen studio as well as printable papers — paper-only practice misses a real and cheap source of lost marks.

May our school or board copy and distribute these?

Yes. They are licensed CC BY-NC-SA 4.0: copy, print, share and adapt them for any non-commercial educational purpose, with credit, passing any adaptation on under the same terms. Recovering real printing costs is fine.

Pick a grade, print a page, and see if it helps.

That is the whole ask. Nothing here needs a decision, a sign-up or a budget line.
