Canada Jay Mathematical Competition (CJMC)

Canada Jay Mathematical Competition (CJMC) is a Canadian math competition open to students in grades K-8. This competition has been created by mathematicians from across Canada.  It was renamed in 2022 from the original name Canadian Mathematical Gray Jay Competition (CMGC) to match the renaming of the Canada Jay bird.

The CJMC is 90 minutes long, consisting of 15 multiple-choice questions based on the grades 5-8 curriculum.

The problems are meant to be a fun fall activity for students and teachers to complement their math curriculum and build students’ problem solving skills. The CJMC offers engaging problems that allow for discussion after the competition and get students excited about math. The competition has 15 questions which take place over 90 minutes. It consists of 3 blocks of 5 questions with an increasing level of difficulty from beginning to end.
