## Caribou News

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.

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

## Goals

The goals of this project are to:

• Provide challenging math activities for interested grade 3-12 students.
• Show that mathematical puzzles can be fun and that competing in math contests can be exciting and modern.

## Upcoming Contests

#### There are no upcoming contests scheduled at this time.

Please check back later. The schedule of contest for the upcoming school year will be released soon.

## How to Participate

The following steps give an overview of how to participate:

• A teacher or librarian must register.
• The teacher must get student access codes (free or paid). For paid access codes, the teacher can buy codes themselves, or allow third parties to pay for them (eg parents).
• On a contest day, the teacher hands out the access codes to their students, which allow the students to take part in the contest. That access code becomes that student's code for the rest of the school year, they will use it to start every contest that year.
• On the evening of a contest day, students can log in to see their results and print certificates using the same access code. Teachers also get detailed statistics about how their students did, in addition to printing certificates.

## Prizes

Cash prizes are given out to the top performing students and schools in the Caribou Cup. Additionally, contest and Caribou Cup certificates can be printed after each test is marked. More information regarding prizes and a sample certificate can be found here.
