Unlocking Math Fun with the Canada Jay Mathematical Competition (CJMC)
Introduction
Math is more than numbers, it’s a way of thinking, solving puzzles, and discovering patterns in the world around us. The Canada Jay Mathematical Competition (CJMC) offers students in grades 5–8 the chance to experience math in a new and exciting way.
What is the CJMC?
The CJMC is an individual written test designed for middle school students (Grades 5–8). It was launched in 2020 by the Canadian Mathematical Society and has quickly become a fall tradition for young problem solvers worldwide.
- Format: Paper-based test at partnering schools
- Languages: English and Chinese
Topics Covered
The contest tests a wide variety of mathematical areas from the middle school curriculum:
- Probability
- Geometry & Symmetry
- Exponents and Order of Operations
- Algebra (sequences, series, patterns)
- Counting Problems
- Elementary Number Theory (primes, composites, GCF, LCM)
- Ratio, Rate & Percent
- Data Analysis (bar and pie graphs)
- Integers & Fractions
Exam Structure
- Duration: 90 minutes
- Question Format: 15 multiple-choice questions
- Difficulty: 3 blocks of 5 questions, with increasing levels of challenge
This block structure encourages students to warm up with approachable problems before moving into more advanced ones.
Awards & Recognition
CJMC recognizes participants both internationally overall and by grade level.
Global Awards (based on total participants):
- Gold Award – International
- Silver Award – International
- Bronze Award – International
- Honour Roll – International
- Performance with Distinction
- Performance with Honours
Global Awards (based on grade level):
- Gold Award – International Grade X
- Silver Award – International Grade X
- Bronze Award – International Grade X
- Honour Roll – International Grade X
Note: Students who win grade-specific awards will not also be awarded Performance with Distinction or Performance with Honours even if they meet the cut-off score.
How to Prepare for the CJMC
Practice with Past Papers
- The Canadian Mathematical Society (CMS) releases past CJMC exams, solving them helps students get familiar with the style and difficulty.

Focus on Core Topics
- Revise key areas like probability, ratios, exponents, patterns, and number theory (primes, LCM, GCF). These appear frequently.

Master Time Management
The test is 90 minutes for 15 questions, but difficulty increases in each block. Practice pacing – don’t spend too long on early problems, and leave time for tougher ones.
Build Problem-Solving Strategies
Practice to draw diagrams, make tables, or test smaller cases for tricky problems. These strategies often simplify what looks complex.
Work on Logical Reasoning
Some CJMC questions are not direct calculations but require reasoning, pattern recognition, and eliminating wrong answer choices.
Review Math Competitions from Similar Levels
Trying contests like Math Kangaroo or other middle school Olympiads helps strengthen competition-style problem solving.
Strengthen Mental Math
Quick calculations with fractions, ratios, percentages, and exponents save time and reduce errors during the test as calculators are not allowed for the exam.
Simulate Exam Conditions
Practice by setting a 90-minute timer, attempting 15 questions in blocks of 5, to get comfortable with the real test format.
Stay Calm & Positive
Remind students that CJMC is about fun and exploration, not just scores. A calm mindset often leads to clearer problem-solving.
Why Students Should Participate
- Boosts Mathematical Thinking: Encourages logical reasoning, pattern recognition, and creative problem-solving.
- Global Exposure: Compete with students worldwide.
- Confidence & Recognition: Awards and distinctions help students celebrate their achievements.
- Fun & Challenging: It’s a low-pressure way to engage with math outside the classroom.
Conclusion
The Canada Jay Mathematical Competition (CJMC) is more than just a math test, it’s an opportunity to discover the beauty of problem-solving, gain international recognition, and have fun while learning. Whether you’re a parent, teacher, or eager student, the CJMC is your chance to turn math into an autumn adventure.
