Grade 4 is the year numbers get big, fractions get real, and writing gets structured. 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 10 000; place value.
Adding and subtracting multi-digit whole numbers using algorithms and estimation.
Multiplying and dividing by one- and two-digit numbers; interpreting remainders.
Equivalent fractions, comparing fractions, mixed numbers, and decimal tenths and hundredths (no multiplication or division of fractions).
Worth watching: this is Grade 4's big conceptual jump. If "is ⅓ bigger than ¼?" gets a guess instead of a reason, it's the unit to practise most.
Patterns and relationships; equations with unknowns; coding with repeating events.
2D and 3D geometry; measuring and constructing angles; location on a grid.
The metric system; area and time; data and probability; financial management and budgeting.
267 students are going on a school trip. Each bus holds 40 students. How many buses does the school need?
Habitats and communities and interrelationships among the organisms that live in them.
Light and sound as forms of energy that have specific characteristics and properties.
The basic principles and functions of machines and their mechanisms.
Rocks, minerals, and Earth’s geological processes.
The Moon doesn't make its own light. So why can we see it shining at night?
Early societies and ancient civilizations up to 1500 CE — their social organization, daily life, and innovations.
The physical and political regions of Canada, their characteristics, and how people use and interact with the land.
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.
