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 and each one in English, French and Persian.

The Caribou Cup is the series of all Caribou Contests in one school year. Each student's ranking in the Caribou Cup is determined by their performance in their best 5 of 6 contests through the school year.

All of our previous contests are available for free online as previous tests.

Goals

The goals of this project are to:

• To improve student's problem solving techniques by providing a wide variety of challenging math activities suitable for all students in grades 3-12.
• Motivate students to get back to their school math when a question needed a technique or formula which they did not remember.
• Show that mathematical puzzles can be fun and that competing in math contests with interactive questions is exciting.

Upcoming Contests

There are currently no upcoming contests scheduled.

Please check back later. The schedule of contests for the upcoming school year will be released early September.
