About This Course
This Grade 9 Mathematics course consolidates and extends students’ understanding of number sense, algebra, data analysis, geometry and financial literacy. Students use mathematical processes, coding and real-life applications to develop reasoning and problem-solving skills.
What You'll Learn
- Use mathematical processes and social-emotional learning skills to solve problems and make connections.
- Work with number sets, powers, rational numbers, ratios, rates, percentages and proportions.
- Develop algebraic expressions and equations, use coding, and analyze linear and non-linear relations.
- Collect, represent and analyze data and use mathematical modelling to investigate real-life situations.
- Apply geometric and measurement relationships to solve problems.
- Make informed financial decisions using mathematical reasoning.
Skills You'll Develop
- Mathematical reasoning and problem-solving
- Algebraic, proportional and spatial reasoning
- Coding and mathematical modelling
- Data analysis and interpretation
- Financial literacy and communication of mathematical thinking
Learning Outcomes
By the end of the course, students will be able to:
- Apply mathematical processes to build conceptual understanding and procedural fluency.
- Make connections between mathematics, knowledge systems, lived experiences, careers and real-life applications.
- Use number sense, powers, ratios, rates, percentages and proportions in mathematical contexts.
- Represent and solve algebraic relationships, including through coding and linear/non-linear relations.
- Collect, represent and analyze one- and two-variable data and apply mathematical modelling.
- Apply geometry and measurement relationships to real-life problem solving.
- Use mathematics to make informed financial decisions.
Course Units
The following reflects the school’s planned organization of the course. Approximate time allocations may be adjusted while all curriculum expectations and required planned learning are maintained.
| Unit | Title / Major Learning Focus | Approx. Time |
|---|---|---|
| 1 | Social-Emotional Learning Skills, Mathematical Thinking and Making Connections | 10 hours |
| 2 | Number Sense, Number Sets and Powers | 20 hours |
| 3 | Algebraic Expressions, Equations, Coding and Relations | 25 hours |
| 4 | Data Analysis and Mathematical Modelling | 20 hours |
| 5 | Geometry and Measurement | 20 hours |
| 6 | Financial Literacy and Integrated Problem Solving | 15 hours |
Assessment
Assessment uses evidence gathered over time from student work, conversations and observations. The final grade for 2026–2027 is determined as follows:
| Component | Weight | How It Is Determined |
|---|---|---|
| Course work throughout the course | 65% | Evaluation evidence gathered throughout the course, with special consideration for consistent and more recent achievement. |
| Mandatory final evaluation — EQAO Grade 9 Mathematics Assessment | 20% | The mandatory EQAO Grade 9 Mathematics Assessment serves as the written final evaluation and is included within the 110 planned learning hours. |
| Attendance and participation | 15% | Based on meaningful engagement and participation in planned learning. |
Examples of Assessment Evidence
Assessment may include conferences, oral explanations, math talks, demonstrations, learning logs, problem sets, quizzes, tests, investigations, coding tasks and the EQAO Grade 9 Mathematics Assessment.
Pathways
The course builds mathematical and transferable skills connected to pathways and careers in science, technology, engineering, skilled trades, business, health sciences, social sciences and many other fields.
The course also develops transferable skills that can be applied in other subjects, postsecondary learning, community contexts and future employment.
Teacher Support
- Students learn primarily through the school's secure online learning environment and receive ongoing support from qualified teachers.
- Teacher-supported conferencing, tutorials and scheduled live support are available as appropriate.
- Teachers use explicit instruction, worked examples, modelling and guided practice to build understanding.
- Students receive support through math talks, oral explanations, manipulatives, diagrams, graphs, tables and algebraic representations.
- Coding, modelling and technology-supported investigations are used to make concepts visible and relevant.
- Individual tutorials, conferencing, formative checks, targeted practice and timely descriptive feedback support progress.
