Common questions
What does my child learn in Grade 10 in Ontario?
Ontario's official curriculum sets out Mathematics, English Language Arts, Science, Social Studies, French for Grade 10 — 519 specific skills in total. The big themes: Mathematics covers quadratic relations of the form y = ax² + bx + c and analytic geometry; Mathematics covers measurement and trigonometry and modelling linear relations; English Language Arts covers oral communication and reading and literature studies. The full list is on this page.
Is this the official Ontario curriculum?
It's built from Ontario's official program of studies, reorganized into plain language — and each subject links to a course page that quotes the ministry's own wording and links to the government source, so you can check our work. One honest caveat: we're not the ministry, curricula do change, and we can't guarantee this reflects the very latest revision, so confirm anything important against the live provincial curriculum data.
My child is finding one of these skills hard. What can I do?
That's normal — every skill on this page is one most kids wobble on at first. MapleMind teaches any of them one-on-one: a short lesson in plain words, a worked example, then solving together. It's free to start, on any device, in 14 languages.

Knowing the list is half the job
The other half is the teaching — and that's what MapleMind does. Pick any skill on this page and see it taught properly, free, in under a minute.
MapleMind isn't affiliated with any ministry of education. We build these guides from each province's official program of studies and refresh them from time to time — but curricula change, and we can't guarantee this page reflects the very latest revision. Always confirm against the live provincial curriculum data. Last updated 2026-08-15.
