Caribou Contests is a global online math competition sponsored by the famous Canadian mathematics professor Thomas Wolf and officially supported by the Canadian Mathematical Society. The competition does not focus on “difficult” questions, but rather stimulates students' interest in mathematics through the “interactive” novel and interesting questions, and improves students' problem-solving skills. Since its inception, the Caribou Contest has quickly become popular in 29 countries around the world. Every year, 160,000 candidates in grades 1-12 compete on the same stage, ranking globally. Another feature of the Caribou Contest is that it is a point game. It provides 6 monthly exams in May of the coming year of October, and selects 5 best scores for rankings. It is an extension of the school math interest community activities and mathematics extracurricular activities. Learning provides a good platform. In 2019, ASDAN China (ASDAN Academy) became the China Organizing Committee Office of the Caribou Contest, providing Chinese students with an opportunity to learn from global students.
In 2020, more than 5,000 Chinese students have participated in Caribou Contests.
