1000以内的数；2、5、10的乘法口诀及对应除法；等值分数；平均数初步；面积、时间与简单找零。

Difficulty & before/after / 难度和前后对比

Broader real-life application and data interpretation sit alongside arithmetic; 2020 added coding and explicit financial literacy.

计算之外进一步突出生活应用与数据解读；2020版纳入编程及明确的理财内容。

ASSESSMENT / 考试与评分

Provincial EQAO Grade 3 math assessment plus school-based reporting; no mandated provincial 20%/25% written-final weight.

3年级参加EQAO省级数学测评，并由学校评定日常成绩；不适用高中20%／25%的规定笔试占比。

PARENT PRIORITY / 家长辅导重点

JK / SK

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

没有传统的数学统一期末笔试，也不采用数学课程百分制总分。教师通过幼儿园学习发展报告沟通学习进度。

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.

省里没有规定一至八年级数学期末统考必须占多少比例；成绩由课堂教师评估。三、六年级参加省级 EQAO 数学测评，但不适用20%／25%的高中期末笔试占比。

GRADE 9 — MTH1W

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

65%平时学业＋20%由 EQAO 九年级数学省测担任期末笔试＋15%出勤及课堂参与（2026–27）。

GRADE 10 MATH

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

65%平时学业＋20%书面期末考试＋15%出勤及课堂参与（2026–27）。

GRADES 11–12 MATH

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

65%平时学业＋25%书面期末考试＋10%出勤及课堂参与（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.

EQAO 是省级测评机构，负责三、六、九年级省测。十至十二年级普通数学期末考试由省里规定制度和权重，但并非全省统一一套试卷；通常由学校／教育局的教师编制或组织考试。

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.

2026–27以前：高中长期使用的一般规则为平时约70%、期末评估约30%；期末评估可能由考试、总结项目等方式组成。2026–27起九、十年级数学变为65/20/15，十一、十二年级数学变为65/25/10。强制书面考试并不代表课程知识本身自动提高了难度。

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.

出勤保障：获批准的合理缺课不会因此扣分。书面期末考试原则上安排在学校指定考试期，九年级 EQAO 数学省测为例外。九年级 EQAO 在2025–26学年占课程最终成绩的10%–30%；2026–27学年统一为20%。

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.

另一项新增毕业要求：适用于2025–26学年或之后进入九年级的学生，自2026–27学年起须达到金融素养毕业要求。通常在十年级职业规划课 GLC2O 中完成，达到至少70%，成绩占该课程5%；它不是十年级数学另外加考的期末考试。
