EQAO Grade 9 math practice and what to expect

The EQAO Grade 9 math assessment is the first provincial assessment that counts toward a course mark, and that changes how students feel about it. The good news is that EQAO publishes more about this one than about any other: the number of questions, the session length, what tools are allowed, a sample test, a formula sheet and three years of released questions. This page gathers what EQAO says, then adds fifteen practice questions we wrote ourselves.

In short

The EQAO Grade 9 Assessment of Mathematics is an online, adaptive test of the MTH1W course: two sessions, 54 questions, about 60 minutes each. EQAO lists the next window as January 12 to February 5, 2027, and results count in the final course mark. Modern Age Coders teaches Grade 9 math live online, in a batch or one to one.

The EQAO Grade 9 math format, in EQAO’s words

EQAO describes the purpose in one sentence: “The Grade 9 Assessment of Mathematics tests the mathematics knowledge and skills students are expected to have learned by the end of the Grade 9 mathematics course.” The table sets out the format exactly as EQAO gives it.

The Grade 9 Assessment of Mathematics, as described on EQAO’s Grade 9 page and assessments page (saved 22 October 2026)
FeatureWhat EQAO says
Next windowJanuary 12 to February 5, 2027
End of the window“The last two days of the administration window should be reserved for students who missed the originally scheduled dates or for extenuating circumstances.”
Sessions“two sessions (Session A and Session B), totalling 54 questions (50 questions that are used to determine a student’s outcome and four field-test questions)”
Length“Each session has two stages and is designed to be completed in approximately 60 minutes.”
Design“The assessment uses a multi-stage computer adaptive testing model”
Strands assessed“Number, Algebra, Data, Geometry and Measurement, and Financial Literacy.”
Not measured directlyThe Mathematical Thinking and Making Connections strand, though “students will be required to apply the mathematical processes while completing the assessment.”
Question types“single-selection, multiple-selection, drag and drop, and drop-down menu questions”
ScoringAn outcome placed by Item Response Theory on a continuum shown as “achievement level 1 to 4”
Afterwards“Students will receive their report from their teacher to bring home.”

What adaptive means for a student

In a multi-stage adaptive test, the second stage of each session depends on how the first stage went. EQAO says the model “adapts to individual students’ performance as they progress through each assessment session.” Two students can see different questions, and that is by design.

The practical lesson is simple: give the first stage full care. Rushing early questions to bank time is a poor trade on an adaptive test, in our view.

Why you will not see your teen’s questions

EQAO explains: “Individual completed assessments and student responses cannot be released to the public since questions are kept for use in future assessments.” Feedback comes through the student’s report and their teacher.

That is also why the released questions and the sample test matter: they are the official window into what the assessment looks like.

Taken from EQAO’s Grade 9 Assessment of Mathematics page (with its question-and-answer section) and EQAO, Assessments, copied on 22 October 2026. EQAO updates these pages, so check them again near the window. We are independent of EQAO.

Calculator, paper, formula sheet

What students can use: calculators and the EQAO formula sheet

Families often ask whether a calculator is allowed and what is on the formula sheet. EQAO answers both on its Grade 9 page.

Calculators

“A built-in calculator is also provided.” And: “Students are also allowed to use their own calculator (scientific or graphing) and a pencil and paper for rough work during the assessment.” Practise on the calculator your teen will actually bring.

The formula sheet

EQAO says “Formulas are given for the area of various geometric shapes.” The sheet is in the e-assessment platform. Open the EQAO Grade 9 formula sheet itself to see which shapes; we do not reproduce it here.

Built-in tools

EQAO lists a line reader, zoom, “a text-to-speech reader and a high-contrast mode”, plus English to French and French to English glossaries meant for French Immersion students and open to everyone in the platform.

How to practise with the formula sheet

Print the formula sheet or keep it open while doing practice. For each geometry question, find the formula on the sheet before calculating. That habit saves time on the day and stops a student trusting a half-remembered formula.

Notice what EQAO describes the sheet as covering: area formulas for shapes. A student should not assume every formula from the course will be printed, and should check the sheet for anything else they rely on.

The introductory session

EQAO says students take part in an introductory session with their teacher, where they “will complete a sample test and tool exploration”, trying tools such as the line-drawing tool, highlighter and eraser.

A student who has never used drag and drop or a drop-down menu in a math question should try them before the real sessions. Familiarity with the platform is the one kind of preparation EQAO actively offers.

Official practice

How to use the EQAO sample test and released questions

EQAO publishes three official resources. Use them in this order. Links go straight to EQAO; we never copy its questions.

  1. Take the sample test once, early. EQAO says its sample test lets students try the tools and question types, and that it “consists of one session with two stages, and a total of 27 questions.” Open the EQAO Grade 9 sample test about four weeks before the window, untimed, to learn the platform.
  2. Read the released questions as a guide to thinking. EQAO publishes released questions for 2023, 2024 and 2025. It says “The 2025 released questions resource includes provincial data for each question.” Start with the 2025 released questions and notice which expectation each question is mapped to.
  3. Use the provincial data honestly. If a question was answered correctly by few students across the province, it is a hard question, not a sign your teen is behind. Spend time on the ones your teen got wrong and could have got right.
  4. Keep the formula sheet beside every geometry question. Find the formula first, then calculate.
  5. Fill gaps with course work and original practice. Once official material has shown the style, review by strand using class notes and sets like ours below.
  6. Sit one full practice under time. About 60 minutes per session, with the calculator and rough paper your teen will use, a week or so before the school’s dates.

What EQAO says about preparation

EQAO’s view, stated on the same page, is that the assessment “does not require additional preparation”, because it follows the classroom curriculum. We agree with the spirit of that. The work that matters is learning MTH1W well.

What official practice adds is calm. A student who has seen the platform, the question types and the formula sheet walks in without surprises.

Hearing it from EQAO

EQAO runs a free webinar, the EQAO Math Session for Parents/Guardians of Grade 9 Students, where its staff discuss questions from the assessment. On 22 October 2026 EQAO listed the next one for Thursday, November 26, 2026, at 6:00 p.m. Eastern time.

EQAO also publishes a framework document with an assessment blueprint, which EQAO says “shows how many questions students complete from the different strands”. It is the authoritative answer to which strands carry the most questions.

Our practice, not EQAO questions

Fifteen Grade 9 math practice questions

Our practice, not EQAO questions. Every item below is original, built around the five strands that EQAO names for this assessment. They are written as open questions so the working shows; on the assessment, questions take other forms. Answers follow.

Our fifteen practice questions by strand (ours)
StrandQuestionsSkills practised
Number1 to 4Scientific notation, laws of exponents, operations with negative fractions, scale and proportion
Algebra5 to 9Solving equations, lines from a point and slope, intersections, equations from tables, linear or not
Data10 and 11Quartiles and box plots, correlation and prediction
Geometry and Measurement12 to 14Right-triangle side lengths, cone and cylinder volume, changing a dimension
Financial Literacy15Depreciation as a repeated percent change
  1. Number. Which is greater, 3.2 × 105 or 4.1 × 104? Explain without writing either number out in full.
  2. Number. Simplify 23 × 24 ÷ 25 using exponent laws, then evaluate.
  3. Number. Calculate −3/4 + 5/6.
  4. Number. On a map with scale 1 : 25 000, two points are 6.4 cm apart. How far apart are they in real life, in kilometres?
  5. Algebra. Solve 3(x − 4) = 2x + 5 and verify.
  6. Algebra. A line has slope 2 and y-intercept −3. Write its equation. Does the point (4, 5) lie on it?
  7. Algebra. Tank A holds 15 L and fills at 2 L per minute. Tank B holds 5 L and fills at 4 L per minute. When do they hold the same amount, and how much is that? What does the point of intersection mean here?
  8. Algebra. A table has x = 0, 1, 2, 3 and y = 7, 4, 1, −2. Write the equation of the relation.
  9. Algebra. Which of these is linear: (a) y = 1, 3, 9, 27 or (b) y = 10, 7, 4, 1, for x = 0, 1, 2, 3? Explain using first differences.
  10. Data. For the data 12, 15, 15, 18, 20, 22, 25, 30, 31, find the median, the first and third quartiles and the interquartile range. Describe the box plot.
  11. Data. A scatter plot of hours practised (x) against errors made (y) slopes downward. Describe the correlation. Can you say practice causes fewer errors? Why or why not?
  12. Geometry and measurement. A 5 m ladder leans against a wall with its foot 1.4 m from the wall. How high up the wall does it reach?
  13. Geometry and measurement. A cylinder and a cone both have radius 3 cm and height 8 cm. Find each volume to one decimal place. How are they related?
  14. Geometry and measurement. If the radius of a cylinder doubles and the height stays the same, what happens to its volume?
  15. Financial literacy. A bicycle loses 15% of its value each year. After 2 years, what percent of its original value is it worth?

Answers, ours

Worked answers to the Grade 9 practice set

Each answer writes the model first, then the numbers, which is the habit that carries furthest in Grade 9. All values were checked in Python.

  1. 3.2 × 105. Its power of ten is one higher. Rewrite 4.1 × 104 as 0.41 × 105; now both have the same power, and 3.2 is larger than 0.41.
  2. 22 = 4. Multiplying powers with the same base adds exponents: 23 + 4 = 27. Dividing subtracts: 27 − 5 = 22 = 4.
  3. 1/12. Common denominator 12: −9/12 + 10/12 = 1/12. Positive, because 5/6 is a little more than 3/4.
  4. 1.6 km. 6.4 cm × 25 000 = 160 000 cm. Divide by 100 for metres (1 600 m) and by 1 000 for kilometres: 1.6 km.
  5. x = 17. Expand: 3x − 12 = 2x + 5. Subtract 2x: x − 12 = 5. Add 12: x = 17. Check: 3(13) = 39 and 2(17) + 5 = 39.
  6. y = 2x − 3; yes. Substitute x = 4: 2(4) − 3 = 5, which matches y = 5, so the point is on the line.
  7. After 5 minutes, at 25 L. Tank A: y = 15 + 2x. Tank B: y = 5 + 4x. Set equal: 15 + 2x = 5 + 4x, so 10 = 2x and x = 5; y = 25. Before minute 5 Tank A holds more; after it, Tank B does. The intersection is the moment they swap.
  8. y = −3x + 7. The initial value at x = 0 is 7, and y drops by 3 each step, so the rate of change is −3.
  9. (b) is linear. Its first differences are −3, −3, −3, all equal. For (a) they are 2, 6, 18, not equal: each term is 3 times the last, which is non-linear growth.
  10. Median 20; Q1 15; Q3 27.5; IQR 12.5. With nine values, the median is the 5th, 20. Using the halves either side of it, the lower half 12, 15, 15, 18 has median 15 and the upper half 22, 25, 30, 31 has median 27.5. The box runs from 15 to 27.5 with a line at 20; whiskers reach 12 and 31. Some classes use a slightly different quartile method, so follow your teacher’s.
  11. A negative correlation; no. As hours rise, errors tend to fall. Correlation alone does not prove cause: students who practise more might differ in other ways too. A careful answer says the data are consistent with practice helping, not that they prove it.
  12. 4.8 m. The ladder is the hypotenuse: h2 + 1.42 = 52, so h2 = 25 − 1.96 = 23.04 and h = 4.8.
  13. About 226.2 cm³ and 75.4 cm³. Cylinder: πr2h = π × 9 × 8 = 72π. Cone: one third of that, 24π. The cone holds exactly one third of the cylinder with the same base and height.
  14. It becomes 4 times as large. Volume depends on r2. Doubling r multiplies r2 by 2 × 2 = 4, and the height has not changed.
  15. 72.25%. Each year the value is multiplied by 0.85. After 2 years: 0.85 × 0.85 = 0.7225, or 72.25%. Not 70%: the second 15% is taken from a smaller amount.

The course mark and the calendar

How EQAO Grade 9 results count, and planning the weeks around them

This is the part of Grade 9 EQAO that raises the stakes. EQAO’s page says: “Results of this assessment are to be included as part of a student’s final course mark”, under the ministry’s Growing Success policy. EQAO does not give a percentage on that page, and schools explain how they apply it.

Asking the school the right questions

Which days within the window will the class write Session A and Session B? Will they be back to back or on different days? EQAO says schools decide, writing each session “in one continuous, supervised sitting”. How does the school include the result in the course mark?

Those answers turn a vague worry into a plan, and teachers are usually glad to give them.

After the window: the Pascal contest

For students who enjoy math, February 2027 has a second date. CEMC says “Students in Grade 9 are eligible to write the Pascal Contest”, and lists it for North and South America on Tuesday, February 23, 2027 and Wednesday, February 24, 2027: “25 multiple-choice questions”, with 60 minutes allowed. That is just over two weeks after EQAO’s window closes.

Pascal is written through a school, and our Waterloo contests page explains it. We promise no level, mark or contest result.

Sources, saved or read 22 October 2026: EQAO’s Grade 9 Assessment of Mathematics page; CEMC Pascal, Cayley and Fermat and contest dates. The plan and the clock arithmetic are ours.

Where your teen is now

Four stages before the Grade 9 assessment

Our own stages, from reviewing with Grade 9 students in the weeks before their sessions.

Grade 9 review stages (ours)
StageWhat it looks like
1. UnfamiliarHas not seen the platform, the sample test or the formula sheet
2. FamiliarHas tried the sample test and knows every question type and tool
3. Secure in algebraWrites and solves linear relations and explains an intersection in words
4. ReadyHas done a timed session, logged mistakes and knows the school’s dates

For parents

Stage 2 costs one evening and removes most of the nerves. Make sure it happens well before January.

Stage 3 is the one that moves the course mark, because algebra runs through MTH1W.

For students

Write the relation or formula before any number. A model on paper is half the answer.

Take the first stage of each session slowly. On an adaptive test, it shapes what comes next.

Questions from Grade 9 families

EQAO Grade 9 math: common questions

What are the 2027 dates for the Grade 9 math assessment?

The window runs from January 12 to February 5, 2027, according to EQAO's assessments page. Its final two days are meant for students who missed their sitting, and each school chooses session dates within the window.

How many questions are on the Grade 9 EQAO math assessment?

EQAO says it has two sessions, Session A and Session B, totalling 54 questions: 50 that count toward the student's outcome and four field-test questions. Each session has two stages and is designed to take about 60 minutes.

Does EQAO Grade 9 count toward the final mark?

Yes. EQAO's page says results are to be included as part of a student's final course mark, under the ministry's Growing Success policy. EQAO does not state a percentage there; ask the school how it applies the result.

Is there an EQAO Grade 9 formula sheet?

Yes. EQAO provides a formula sheet in the e-assessment platform and on its website, and says formulas are given for the area of various geometric shapes. Open the sheet on EQAO's site to see exactly which ones.

Can students use a calculator?

Yes. EQAO says a built-in calculator is provided, and that students may also use their own scientific or graphing calculator, plus pencil and paper for rough work.

Is there a free EQAO Grade 9 practice test?

EQAO offers a free sample test on its website. EQAO says it has one session with two stages and 27 questions, and lets students try the tools and question types. EQAO also publishes released questions for 2023, 2024 and 2025.

Did EQAO write your practice questions?

No. Every question here is original to Modern Age Coders, built around the five strands EQAO names. For official items, use the sample test and released questions on EQAO's own site, which this page links to.

Is the assessment adaptive?

Yes. EQAO says it uses a multi-stage computer adaptive testing model that adapts to each student's performance as they move through each session. So two students may see different questions.

Is extra preparation needed?

Not in EQAO's view: because the questions follow the classroom curriculum, EQAO says no additional preparation is required. In practice, learning MTH1W well is the main job, and one look at the sample test and the formula sheet removes most surprises.

Can we see our teen's completed assessment?

No. EQAO says completed assessments and student responses cannot be released to the public because the questions are kept for future assessments. Students receive a report from their teacher.

When are lessons available?

Weekdays or weekends, flexible: choose your batch, or for a very personalised plan choose 1-on-1 at your convenience, weekend mornings or weekdays. Ontario stays on its winter clock for the whole January to February window, so a lesson time agreed in November holds steady through it.

What do classes cost?

Your first class is free. After it, one monthly payment covers eight live lessons, with no semester lock-in. Amounts for a batch and for a private teacher sit in the price panel.
