If you're wondering what math you need to know for the Ontario Mathematics Proficiency Test (MPT), the answer is straightforward: Grade 9 math. Not calculus. Not advanced algebra. Just the fundamentals from the Ontario curriculum.

Here's exactly what to study.

The Four MPT Math Strands

The MPT math section covers four strands from the Ontario curriculum:

1. Number Sense and Numeration

What you'll see:

Whole numbers, fractions, decimals, and integers
Percentages and ratio problems
Proportional reasoning
Order of operations

Example question type:

A recipe calls for 3/4 cup of flour. If you want to make 2.5 times the recipe, how much flour do you need?

Study focus:

Converting between fractions, decimals, and percentages
Solving proportion problems
Working with ratios

2. Measurement and Geometry

What you'll see:

Area and perimeter of 2D shapes
Volume of 3D figures
Pythagorean theorem
Angle relationships
Unit conversions

Example question type:

A rectangle has a perimeter of 30 cm and a length of 10 cm. What is its area?

Study focus:

Area formulas (rectangle, triangle, circle)
Volume formulas (prisms, cylinders)
Pythagorean theorem applications
Converting metric units

3. Patterning and Algebra

What you'll see:

Linear relationships (y = mx + b)
Solving one- and two-step equations
Pattern recognition and extension
Graphing linear equations

Example question type:

The equation y = 2x + 3 represents a line. What is the y-intercept? What is the slope?

Study focus:

Understanding slope and y-intercept
Solving for x and y
Graphing linear equations
Recognizing patterns in tables

4. Data Management and Probability

What you'll see:

Reading and interpreting graphs
Calculating mean, median, mode
Understanding probability
Drawing conclusions from data

Example question type:

A survey of 100 students found that 25 prefer math, 40 prefer science, and 35 prefer English. What percentage prefer science?

Study focus:

Interpreting bar graphs, line graphs, circle graphs
Calculating central tendency (mean, median, mode)
Basic probability (fractions and percentages)

What's NOT on the MPT

To save you time, here's what you don't need to study:

❌ Quadratic equations (x²)
❌ Advanced algebra (factoring complex polynomials)
❌ Trigonometry (sin, cos, tan)
❌ Calculus (derivatives, integrals)
❌ Advanced statistics (standard deviation, correlation)

If it's not in the Grade 9 curriculum, it's not on the test.

How the MPT Tests These Concepts

The MPT doesn't just ask you to calculate. It tests whether you understand the concepts well enough to teach them. Expect:

Multiple choice with distractors based on common student errors
Word problems requiring you to identify the right operation
Questions about student misconceptions (pedagogy + content combined)

Where to Practice Each Strand

Strand	Best Free Resource
Number Sense	EQAO Grade 9 questions
Measurement	Khan Academy Grade 9
Algebra	Numera linear equations
Data Management	EQAO data interpretation

Sample MPT-Style Questions

Number Sense

A student calculates 25% of 80 and gets 20. Another student says the answer should be 200. Who is correct? What error did the other student make?

Geometry

A triangle has a base of 6 cm and a height of 4 cm. A student calculates the area as 24 cm². Is this correct? If not, what is the correct area?

Algebra

If 3x + 5 = 20, what is the value of x? Show your work.

Data

The mean of five test scores is 78. Four of the scores are 82, 75, 80, and 76. What is the fifth score?

Study Tips by Strand

For Number Sense

Practice mental math with percentages
Work on fraction/decimal conversions until they're automatic
Do lots of word problems

For Geometry

Memorize area formulas
Practice drawing diagrams from word problems
Check your units (cm vs cm²)

For Algebra

Understand what slope and y-intercept mean in real contexts
Practice solving equations step by step
Check your answers by substituting back in

For Data

Read graphs carefully — titles, axes, scales
Remember: mean = average, median = middle, mode = most frequent
Practice interpreting what data means

The Bottom Line

The MPT math section is designed to test whether you have the foundational math knowledge needed to teach elementary and middle school. It's not trying to trick you with advanced concepts.

If you can confidently handle Grade 9 EQAO questions, you can handle the MPT math section.
