The Senior Kangaroo 2020 will take place over 2 days, 25th/26th November
Providing an additional opportunity for problem solving
The Senior Kangaroo is a follow-on round to the Senior Mathematical Challenge. It is a 60-minute competition consisting of 20 problems.
Unlike the Senior Mathematical Challenge, the answer to each Senior Kangaroo problem is a positive integer less than 1000. Achieving a high score requires engagement with the problems, without the benefit of five options to choose from.
We invite several thousand qualifying UK-based students from the Senior Mathematical Challenge to take part in the Senior Kangaroo. Entry to the competition is by invitation only and is based on a qualifying score, which is variable from year to year.
How do I take part?
The competition is only open to invited students in schools and colleges based in the UK.
Invitations to participate in the Senior Kangaroo will be clearly indicated in your results from the Senior Mathematical Challenge. Invitees will receive automatic online access to the competition but there will also be an option to receive a paper version.
What happens after the Senior Kangaroo?
Each participant receives a Certificate of Qualification and the top-scoring 25% of participants each receive a Certificate of Merit.
How can I prepare for the Senior Kangaroo?
Teachers can use past Senior Kangaroo papers as a source of high-quality problems to encourage their students to think mathematically and to prepare for the competition. We are delighted to be working with DrFrostMaths to help teachers use past problems in the classroom.
We also sell downloadable past papers and books which can help students to prepare for our competitions.
We are proud to be the UK member of the Association Kangourou sans Frontières, a collaborative association whose purpose is to promote mathematics among young people around the world. Around six million young people take Kangaroo competitions each year.
The name Kangaroo acknowledges the contribution made by Australia to establishing large-scale mathematics contests.
