What actually changed when Ontario de-streamed Grade 9 math, what MTH1W covers strand by strand, and how to structure tutoring sessions that reinforce how the course is meant to be taught.
Since September 2021, every Ontario Grade 9 student takes the same math course. The old split between academic (MPM1D) and applied (MFM1P) math is gone, replaced by one de-streamed course, MTH1W, that folds algebra, modelling, and financial literacy expectations once reserved for the academic stream into a single classroom for everyone (Ontario Ministry of Education). If you are picking up a Grade 9 student now, the course has changed more than the grade number suggests.
This guide covers what MTH1W includes, where students tend to get stuck, and how to structure sessions around it.

What Changed When Ontario De-Streamed Grade 9 Math
Streaming meant a student was sorted into an academic pathway aimed at university or an applied pathway aimed at college or the workplace, often before there was much evidence to base that choice on. Ontario ended the split for math first, starting with students entering Grade 9 in September 2021, and MTH1W remains the current curriculum for 2026-2027.
The results are improving but still mixed. On the EQAO Grade 9 Assessment of Mathematics, 59 percent of students met the provincial standard in 2025-2026, up from 58 percent the year before and 54 percent in 2023-2024 (EQAO, released September 2026). That is real progress, but a large share of any tutoring roster is still working below the standard, in a course that no longer separates students by pathway.
What Does the De-Streamed Grade 9 Math Curriculum (MTH1W) Actually Cover?
MTH1W is organized into five content strands, Number, Algebra, Data, Geometry and Measurement, and Financial Literacy, plus a Mathematical Thinking and Making Connections strand and a Social-Emotional Learning strand that are woven through the other five. Algebra now includes coding and linear and non-linear relations for every student, not only those once streamed into academic math (Ontario Ministry of Education).
| Strand | What It Covers | Where Students Often Need Help |
|---|---|---|
| Number | Powers, rational numbers, ratios, rates, percentages | Connecting integer and fraction fluency to algebra |
| Algebra | Linear and non-linear relations, coding, algebraic expressions and equations | Turning a word problem into an equation or graph |
| Data | Data collection and analysis, mathematical modelling | Building a model from a real dataset, not just reading one |
| Geometry and Measurement | Geometric and measurement relationships in real contexts | Applying a formula to an unfamiliar real-life scenario |
| Financial Literacy | Budgeting, interest, informed financial decisions | Connecting percent and ratio skills to real money contexts |

A few of these strands are new territory even for teachers who taught the old academic or applied courses: coding sits inside Algebra, financial literacy is its own strand, and mathematical modelling, turning a real situation into a data-based prediction, runs through Data as a full expectation.
Where Grade 9 Math Students Tend to Get Stuck
Tutors and classroom teachers who have taught MTH1W consistently point to the same pinch point: the algebra strand's linear and non-linear relations move faster than the old Grade 8 course prepared most students for, since that content once sat mostly in the academic stream. A student comfortable with numeric work can still stall the moment a word problem asks them to represent a real situation as an equation or a graph. Financial literacy and data-modelling tasks trip up a different group, students who can follow a formula but have not built one from a real scenario before.
None of this means a student is behind in a way that needs fixing first. It means your early sessions are better spent finding which strand, and which expectation inside it, is the actual gap, rather than reteaching the whole course. This is also where matching a student with a tutor who knows the strand they are stuck on matters.
How Ontario Wants This Course Taught, and What That Means for Tutoring
The Ministry's guidance for de-streamed classrooms leans on a set of practices: building relational trust before content, using low floor-high ceiling tasks so every student can enter a problem at their own level, connecting math to real-life situations, and assessing informally and continuously rather than through one big test (Ontario Ministry of Education, Introduction to Effective Teaching Practices for the De-streamed Grade 9 Math Classroom). Those practices translate directly into a one-on-one session, arguably better than into a class of thirty.
- Start where the student actually is. A low floor-high ceiling entry question tells you more in five minutes than a generic diagnostic worksheet.
- Anchor new concepts in something real. Use an actual budget, dataset, or simple program before moving to the abstract version.
- Check understanding every session, not just before a test. One applied question at the end tells you what to plan for next time.
- Build the relationship, not just the content. Knowing what a student is actually interested in gives you contexts that land.
A Simple Way to Structure Your Tutoring Sessions
A consistent structure keeps sessions aligned with how the course is taught in class, and is part of what makes a steady weekly tutoring schedule work.
- Open with a two-minute check-in on which strand the student covered in class that week, so you reinforce the same material.
- Give a low floor-high ceiling entry problem to see where the student can genuinely start.
- Work one concept from concrete to abstract: a real budget before a financial literacy formula, an actual dataset before a modelling question.
- Ahead of an EQAO window, January for semester one or June for semester two, build in light familiarity with the format without teaching to the test.
- Close with one applied question. That single data point tells you what to plan for next session.
