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.
• The contact person logs in and either purchases password credits herself/himself or enables parents to pay (please read all of the contact home page after loging in).
• 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.

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:

• http://www.mathkangaroo.org/2010page/Clark/clark/pdb/

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.
