GRADE 4 · MATHEMATICS (2020)

Grade 4

Revised Sep 2020
REFORM DATE

Effective September 2020; replaces the 2005 Grades 1–8 mathematics curriculum. No separate new Grade 4 mathematics syllabus introduced in September 2026.

KEY EXPECTATIONS

Numbers to 10,000; decimal introduction; division by a one-digit number; facts to 10×10; equations with unknowns; rectangular area, metric units, spending choices.

Difficulty & before/after

Additional coding/modelling and financial contexts widen the set of skills students must apply; difficulty depends on the individual task.

ASSESSMENT

Teacher-based assessment and provincial report cards; no mandated province-wide 20%/25% math written final.

PARENT PRIORITY

Fluency in multiplication facts, long division, decimals and multistep questions matters.

Learning difficulty, practice and proficiency

Assessment and exam policies

Exams, marks & test writers

JK / SK

No conventional mandatory mathematics final exam or numerical mathematics course mark. Educators document learning through the Kindergarten Communication of Learning.

GRADES 1–8

No province-wide prescribed percentage for a school mathematics final exam. Classroom teachers evaluate achievement. Grades 3 and 6 take provincial EQAO math assessments; these are not a 20% or 25% math final-exam rule.

GRADE 9 — MTH1W

65% classroom work + 20% EQAO Grade 9 mathematics assessment as the written final exam + 15% attendance and participation (2026–27).

GRADE 10 MATH

65% classroom work + 20% written final exam + 15% attendance and participation (2026–27).

GRADES 11–12 MATH

65% classroom work + 25% written final exam + 10% attendance and participation (2026–27).

WHO WRITES THE QUESTIONS?

EQAO is a provincial testing agency: it develops/operates Grade 3, 6 and 9 provincial assessments. For regular Grade 10–12 math exams, the province sets the rules and weight, but does not prescribe one identical province-wide final exam paper; school/board educators prepare or administer local exams.

Before 2026–27: the longstanding general secondary assessment framework was approximately 70% work completed during the course and 30% final evaluation, which could include an exam, culminating task or other suitable activity. Since 2026–27, Grade 9/10 math uses 65/20/15, and Grade 11/12 math uses 65/25/10. A larger required written exam does not mean a higher mathematical syllabus level.

Attendance safeguard: excused absences are not penalized. Written final exams ordinarily occur in designated exam periods; Grade 9 EQAO mathematics is the stated exception. For Grade 9, the EQAO share was 10–30% in 2025–26 and becomes 20% in 2026–27.

Other new graduation rule: for students who entered Grade 9 in 2025–26 or later, a financial-literacy requirement takes effect in 2026–27. It is normally completed in Grade 10 Career Studies (GLC2O): at least 70% is required, and its result counts for 5% of that course. It is not an additional Grade 10 mathematics final exam.
