Canadian Mathematical Gray Jay Competition (CMGC) is a new Canadian math competition for students in grades 5-8. This competition has been created by mathematicians from across Canada. 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 CMGC will offer engaging problems that will allow for discussion after the competition and get students excited about math.

ASDAN China (ASDAN Academy) is partnering with the CMGC to bring the contests to Chinese students from 2020.
