What Grade 8 covers in Ontario — and how to practise it at home

Grade 8 is the runway to high school — consolidating everything, with independence as the quiet second subject. 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.

Math — the 2020 Ontario math curriculum, in teaching order

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.

1

Rational & Irrational Numbers

Weeks 1–6 · September–October

Rational numbers, powers, square roots, and an introduction to irrational numbers.

2

Proportional Reasoning

Weeks 7–12 · October–November

Ratios, rates, percents, and proportional relationships.

3

Algebra & Linear Relations

Weeks 13–19 · November–January

Algebraic expressions, solving multi-step equations, and linear relations.

Worth watching: linear relationships are the front door to high-school math. Comfort with "what happens to y when x grows?" matters more than speed.

4

Lines & Angles

Weeks 20–26 · January–February

Angle relationships, parallel lines, and the Pythagorean relationship.

5

Measurement & Volume

Weeks 27–32 · March–April

Surface area and volume of prisms, cylinders, and composite figures.

6

Data & Probability

Weeks 33–38 · April–May

Data collection, analysis, misleading representations, and probability of compound events.

7

Financial Literacy

Weeks 39–43 · May–June

Budgeting, credit and interest, and evaluating financial decisions.

Try one — a real Grade 8 question

Math · Percent

A $40 video game is on sale at 25% off. What do you pay?

A typical first answer
$10
Homework Hub's feedback
You found the discount — 25% of $40 is indeed $10. But the question asks what you PAY. The discount comes off the price…
Next try
$30
Exactly — $40 − $10 = $30. Finding the discount is step one; the price you pay is the step people forget. 🎮

Science across the year

1

Cells

Weeks 1–11 · September–November

The basic structure and function of plant and animal cells and cell processes.

2

Fluids

Weeks 12–22 · November–January

Basic fluid mechanics, including the properties and uses of fluids.

3

Systems in Action

Weeks 23–32 · February–April

Different types of systems and the factors that contribute to their safe and efficient operation.

4

Water Systems

Weeks 33–43 · April–June

The characteristics of Earth’s water systems and factors that affect these systems.

Science · Light vs Sound

In a storm, why do you see the lightning before you hear the thunder?

A typical first answer
Because the lightning happens first.
Homework Hub's feedback
They actually happen at the same instant — the flash and the boom are the same event! The difference is in how fast each one travels to you…
Next try
Light travels much faster than sound.
Exactly — light arrives almost instantly; sound plods along at ~340 m/s. Count the seconds between them and you can even estimate the distance. ⚡

History & Geography — Social Studies grows up

In Ontario, Grades 7–8 split Social Studies into separate History and Geography strands — just like at school.

1

Creating Canada, 1850–1890

Weeks 1–22 · September–January

The creation of Canada from 1850 to 1890 — Confederation, building a new country, and westward expansion; include honestly and respectfully how these changes affected First Peoples and other communities (such as loss of land and pressure on their ways of life), at a general, age-appropriate level and from their perspectives, without graphic detail.

2

Canada, 1890–1914: A Changing Society

Weeks 23–43 · February–June

Canada, 1890–1914: a changing society shaped by immigration, industrialization, and regional development.

1

Global Settlement: Patterns and Sustainability

Weeks 1–22 · September–January

Global settlement patterns and sustainability — where and why people live where they do; describe any data in words.

2

Global Inequalities: Economic Development and Quality of Life

Weeks 23–43 · February–June

Global inequalities in economic development and quality of life, and how they can be measured and addressed.

English & French — skills that build weekly, not units

How language works in Grade 8

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.

Practice that follows this exact sequence

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.
