About Caribou

The Caribou Mathematics Competition is a world wide online contest that is held six times throughout the school year. Each of these days, five contests are offered, one for each of the grade levels 3/4, 5/6, 7/8, 9/10 and 11/12.

The Caribou Cup is the series of all Caribou Contests in one year. Each student's ranking in the Caribou Cup is determined by their performance in their best five of six contests through the school year.
