## Caribou News

The Caribou Mathematics Competition is a North America wide online contest that is held on six days in a school year, 2012/13 in its fifth year. On each of these days a contest is offered for each of the age groups of grades 3/4, 5/6, 7/8, 9/10 and 11/12. Contests are provided in both English and French.

The Caribou Cup is the series of all Caribou Mathematics Contests in one school year. The ranking in the Cup is based on the total number of points achieved in the 5 best contests throughout the whole school year.

## Goals

The goals of this project are to:
• Provide challenging math activities for interested Grade 3-12 students in North America.
• Show that mathematical puzzles can be fun and that competing in mathematical contests can be exciting.

## How To Participate

The following steps give an overview of how to participate.
• A teacher/librian registers as contact person once for ever. (Contact details can be changed online later). If the contest is free (all grade 3/4 contests and the first contest in the school year in October for all other grade levels) then proceed with point 4.
• Parents pay online (click 'Purchase Password Credits' on home page), teachers get the credits automatically on their account and get sent an email with the list of benefiting students. (Parents do not get passwords.)
• For each contest (whether free or with a fee) the contact person has to log into their contact page and request passwords.
• On the contest day teachers hand out passwords to their students, students write the contest online.
• On the evening of each contest day students see their results and can print ceritifcates, contact persons can inspect the results of their students and print certificates too.
More details can be found here.

Parents can register with us on this page to receive an email when we announce our next contest and any other information we send out. You can remove your registration here.

## Practice Questions

All problems of previously held competitions are available online in our practice tests, allowing students to see what the online test will look like and what has to be typed in. The type of problems are similar to those of the Kangaroo problem database: Problem sets are available at this web page. Teachers, students and parents are recommended to use both for practice questions.

Kangaroo mathematics contests started in France, in 2001, and have been adopted by many countries, including Canada and the United States.
