Overview

Mathematics is a powerful tool used every day to solve real-world problems. In kindergarten to Grade 6, there is a focus on numeracy skills, which provides students with a solid foundation of mathematical knowledge. Numeracy skills support real-world pursuits, including managing time, using and managing finances, following instructions, understanding statistics, navigating with maps and reading schedules and statements. 

Experiences with mathematics help students develop appreciation for the patterns and relationships that describe multiple aspects of the world and its future possibilities. With a focus on numeracy, the mathematics curriculum provides all students with a solid foundation of mathematical knowledge, understanding and skills to set them up for future success.

In grades 7 to 9, students connect concrete experiences to their comprehension of abstract concepts. Students apply their knowledge of number facts to operations with various types of numbers, including natural, integer and rational numbers, when using commonly recognized algorithms. 

In developing algebraic thinking skills, students transfer their understandings of properties of numbers to new contexts. They communicate by using conventional mathematical symbols, notation and vocabulary. Students build an understanding of geometric properties, theorems and formulas, enabling them to recognize complex relationships, solve real-world problems and propose innovative solutions. Through mathematics, students develop logical thinking skills that support effective decision making in a variety of situations.  

Studying and mastering mathematics can lead to jobs in computer science, construction, artificial intelligence, teaching, engineering and many other fields.

Draft 7 to 9 mathematics curriculum

  • What we heard about the draft Kindergarten to Grade 6 (K to 6) curriculum

    We considered feedback from multiple engagement activities and heard some common themes:

    • Content load: Content load is heavy, particularly in Grade 7, and too much content results in surface-level learning, which can be a barrier to students’ success in later grades.
    • Sequencing of content: While the content is generally appropriate and well-sequenced, there are opportunities to improve the progression of learning between grades, such as shifting content between grades and adding review outcomes.
    • Alignment and clarity: Education partners noted opportunities to improve alignment and clarity, such as improving KUSP alignment, removing inconsistent terminology and notation, shifting the presentation of materials and addressing unclear phrasing.
    • Real-world applications: Education partners noted the benefits of adding real-world examples and applications to further engage students and demonstrate the relevancy of mathematics in their lives.
  • What we updated

    We made the following content updates:

    • Content load: Refined content that was identified as redundant or repetitive to allow students to gain a deeper understanding of key concepts.
    • Sequencing of content: Adjusted the progression of learning or ordering of content across or within grades.
    • Alignment and clarity: Revised statements for clarity and alignment among knowledge, understandings, and skills and procedures to ensure that the focus of learning is clear to parents, students and teachers.
    • Real-world applications: Added real-world examples and applications throughout grades 7 to 9 to provide increased opportunity for students to engage in mathematics. 
  • Other content-specific updates

    • Operations on decimal numbers: Added multiplication and division of decimal numbers to Grade 7.
    • Repeating decimal numbers: Added repeating decimal numbers to Grade 8.
    • Bar and circle graphs: Added content on bar and circle graphs to Grade 8.
    • Set notation of sample space: Shifted set notation of sample space from Grade 7 to Grade 8 to reduce load in Grade 7 and to build a stronger learning sequence in the probability organizing idea.
    • Unions and intersections: Shifted unions and intersections from Grade 8 to Grade 9 to build a stronger learning sequence.

Current and draft curriculum comparison

The following table shows how elements in the current 7-9 mathematics curriculum, updated in 2016, compare to elements in the draft 7-9 mathematics curriculum. The comparison provides examples and does not represent all the changes that were made. 

 Current curriculum (2016) examplesDraft curriculum (August 2025) examples
Real numbersStudents learn about rational numbers but do not explore absolute value or scientific notation. Students learn about irrational numbers, sets, and notation to better understand numbers.

Students are introduced to absolute value and scientific notation to deepen understanding of the magnitude of numbers.
Equations and inequalitiesStudents solve linear equations and inequalities. Students learn to solve quadratic equations and linear inequalities to increase understanding of multiple solutions.

Students are introduced to set builder notation to communicate mathematical understandings.
Polynomial expressionsStudents add, subtract, multiply, and divide polynomials.Students are introduced to identities to support strategies of expanding and factoring polynomials.
Geometric objectsStudents construct perpendicular lines and angle bisectors.Students use symbols and symbolic notation to communicate relationships among angles, lines and objects.
TheoremsStudents explore the Pythagorean theorem. Students are introduced to additional theorems, including angle theorems and triangle properties, to strengthen mathematical reasoning and problem-solving skills.
2-D and 3-D shapesStudents explore area and volume of 3-D shapes.Students explore volume of composite 3-D shapes and calculate surface area and volume of pyramids to expand on their spatial and proportional reasoning.
FunctionsStudents are not introduced to functions.Students develop knowledge of functions and their characteristics to support understanding of the relationship between variables.
Data collection, interpretation, and representationStudents learn about factors that influence data collection.Students interpret sample data by analyzing distributions, focusing on shape and spread through graphical representation.
ProbabilityStudents solve problems involving independent events.Students explore how multiple events influence probability and use representations to visualize and analyze probabilities.
