Kangourou sans Frontières (KSF) is an independent association, whose purpose is to organise the annual Kangaroo contest with the aim of promoting mathematics among young people around the world. The name sounds strange, but recognises the fact that the organisation was inspired by the Australian Mathematics Trust.
Each year over six million school pupils aged 5-18 from more than 50 countries throughout the world take part at various levels. So when you sit the Kangaroo you are part of a huge community of maths students! The UKMT has been involved in Kangaroo activities for many years and uses the hour-long multiple-choice papers (in English) as an extension to the Intermediate Challenge.
Further details can be found at the KSF website Kangourou sans Frontières.
Usually around 5,500 pupils from all three year groups sitting the Intermediate Challenge are invited to sit either the grey or pink Kangaroo papers, dependent on school year. In 2014, entry numbers were increased to around 8,000 invitees.
The Kangaroo papers are taken no earlier than the third Thursday in March, and solutions are not made public until the following month.
|England and Wales||Scotland||Northern Ireland|
|Grey||Year 9 or below||S2 or below||Year 10 or below|
|Pink||Year 10 and 11||S3 and S4||Year 11 and 12|
Certificates of merit are awarded to the top 25%, certificates of participation to everyone else taking part and keyfobs to everyone (see link for keyfob puzzles).
