Grade 3 is a step-up year: multiplication arrives, reading shifts from learning-to-read toward reading-to-learn. Here is the year as Ontario schools actually teach it — unit by unit, in order — so you can see what your child is working on right now, and what's coming next.
Ontario math runs as a sequence: each unit builds on the one before it. The week ranges below follow the school year from September; teachers vary pacing.
Reading, representing, comparing and ordering whole numbers to 1000; place value.
Adding and subtracting to 1000 with regrouping using efficient strategies.
Multiplication and division facts and strategies to 7 x 7.
Worth watching: this is the year times tables form. Little and often beats cramming — they need to be automatic before Grade 4 uses them everywhere.
Representing, comparing and naming simple fractions (halves, thirds, fourths, eighths) of objects, sets and regions; no sixths and no operations on fractions.
Number and shape patterns; equality; simple coding to model patterns.
2D and 3D properties; angles as turns; location and movement.
Length, mass, capacity; perimeter and area; time; data; money and change.

Life in early Canadian communities from 1780 to 1850 — the diverse peoples who lived here, including First Nations and Métis peoples and newcomers, their daily lives and work, and how communities formed; told respectfully and centring First Peoples' presence and perspectives, focused on understanding different ways of life.
Living and working in Ontario: municipalities, land use, and the natural environment of the region.
Unlike math and science, the language curriculum isn't taught as a sequence of units — it's a set of skills that deepen all year: reading comprehension and inference, writing structure and conventions, vocabulary, and oral communication. French works the same way. Homework Hub practises these as grade-matched weekly skills — a reading passage with real comprehension questions, a sentence to fix, a short prompt to write to — rather than pretending there's a unit list.
Homework Hub generates fresh questions matched to these very units — in season, at your child's level, marked with hints that teach. You set the days; it does the rest.

School boards and teachers vary pacing — week ranges are a typical rhythm, not a rule.
