Grade 9 | Ontario Mathematics Curriculum

GRADE 9 · SECONDARY

Grade 9 / 9年级

MTH1W · De-streamed Mathematics

2021 curriculum + 2026 assessment / 2021年新大纲＋2026年评分改革

WHEN & WHAT CHANGED / 改革时间与内容

September 2021: de-streamed MTH1W replaced the Grade 9 Academic (MPM1D) and Applied (MFM1P) courses. September 2026: the mandatory 20% EQAO written-final rule begins.

2021年9月：不分流 MTH1W 替换原学术 MPM1D 及应用 MFM1P。2026年9月：EQAO省测作为规定20%书面期末成绩的政策实施。

CURRICULUM EXPECTATIONS / 课程要求

Number, algebra, coding, linear and non-linear relationships, geometry and measurement, data, financial literacy, mathematical modelling and explaining reasoning.

数与运算、代数、编程、线性及非线性关系、几何测量、数据、理财、数学建模与推理说明。

Difficulty & before/after / 难度和前后对比

Compared with the former Applied route, some students may face broader academic demands; compared with the former Academic route, topic-by-topic difficulty cannot be summarized by a simple percent. New coding/financial literacy and a common non-streamed pathway are real changes. In 2026, the EQAO now has a fixed 20% stake.

相较旧应用班路线，部分学生可能面临更广的学术要求；相较旧学术班则不能用一个百分比断言全面更难。统一不分流、编程和理财才是实质更新；2026年EQAO权重固定为20%。

2026–27 EXAMS / 2026–27考试与占比

65% classwork + 20% EQAO mathematics written-final assessment + 15% attendance/participation. EQAO is developed/administered at the provincial level.

65%平时学业＋20% EQAO九年级数学省测（期末笔试）＋15%出勤参与。EQAO由省级机构组织。

PARENT PRIORITY / 家长辅导重点

Review Grade 8 fractions, exponents, equations and graphing well before EQAO.

提前补强八年级分数、指数、方程及函数图像，为 EQAO 做准备。

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。
