About Caribou
The Caribou Mathematics Competition is a worldwide online contest that is held six times throughout the school year. Each of these days, six contests are offered, one for each of the grade levels 2, 3/4, 5/6, 7/8, 9/10 and 11/12 and each one in English, French, Persian, Mandarin, Ukrainian, and Azerbaijani.
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 support materials (written solutions, current year and previous years contests as online practise tests, online math and logic games, online mini courses) are also available without contest participation. Many of them are free.
Caribou Math from Home
Caribou contests have always been suited for home schooling. If you would normally participate at school but are unable to due to school closures, because you are self-isolating, or because you are opting to home school, please rest assured you can sign up and participate from home.
There are a few options depending on your situation:
- Schools organize participation but allow students to write from home when needed.
- Parents organize participation for their students at home, registering them with the Caribou Virtual School.
- Parents organize participation for their students at home, registering as a home school.

Goals
The goals of this project are to:
- Show that mathematical puzzles can be fun and that competing in math contests with interactive questions is exciting.
- To improve student's problem solving techniques by providing a wide variety of challenging math activities suitable for all students.
- Motivate students to get back to their school math when a question needed a technique or formula which they did not remember.
Upcoming Contests
Contests can be started between 7:30AM and 3:30PM local time of the participating school by default. Students are given 50 min to complete the test.

Calcrostic of the Day
Calcrostics are a trademark in a Caribou Contest - one appears in nearly every contest.
Today's Calcrostic Puzzle
ab - cb = db + / - × - ebb / a = cb = = = = = eab / ea = eb
Yesterday's Solution
24 + 12 = 36 + / / × - 48 / 2 = 24 = = = = = 72 / 6 = 12
