Providing an additional opportunity for problem solving

The Andrew Jobbings Senior Kangaroo is a follow-on round to the Senior Mathematical Challenge. It is a 60-minute Challenge 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.

Date: 2 December 2021

Eligible year groups: England and Wales - Years 13 and below, Scotland -  Years S6 and below, Northern Ireland - Years 14 and below

Time allowed: 60 minutes

Entry fee: Invitation only or via discretionary

Discretionary entries will open on the same day results for the Senior Mathematical Challenge are released.

Entry deadline (paper): Midnight, Friday 26th November 2021

Entry deadline (online): Midnight, Wednesday 1st December 2021

How to take part

The Challenge 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 Challenge but there will also be an option to receive a paper version.

For the first time, discretionary entries will be available to purchase for schools. This is currently the only Kangaroo open for discretionary entry. Discretionary entries will open after results for the Senior Mathematical Challenge have been released.

Kangaroo Entries

Managing entries

Kangaroos will automatically be hosted in the same way in which you hosted the Senior Mathematical Challenge. If you have qualifiers from the online SMC you will be given online Senior Kangaroo logins for your students. If you have qualifiers from the paper SMC you will be given paper entries into the Senior Kangaroo. 

If your students are sitting the Senior Kangaroo on paper you will need to download and print the question papers and answer sheets in school. We only send out hard copy question papers for first round Challenges.

Once your students have finished sitting the Senior Kangaroo you will then need to upload their answer sheets to your Challenges Profile.

Preparing for the Challenge

We hope that taking part in the Senior Kangaroo is a stimulating and rewarding experience for all students, whether or not they have prepared.

You can utilise our previous online Challenges, download past papers, solutions and investigations here. They are a great resource containing high-quality problems designed to encourage mathematical thinking and prepare students for the Challenge. We are also 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 with their preparation.

Scoring

Scoring rules for the Andrew Jobbings Senior Kangaroo are as follows:

  • 5 marks are awarded for each correct answer
  • In the Senior Kangaroo you will NOT lose marks for getting questions wrong

Awards

Each participant receives a Certificate of Qualification or Participation, depending on their entry route, and the top-scoring 25% of participants each receive a Certificate of Merit.

Certificates are pre-populated with student names and can be downloaded and printed as soon as results are released.

The 2020 award thresholds were:

Andrew Jobbings

Andrew was a major contributor to the UKMT; he helped to set up, and contributed prolifically to, many of our activities. He was a key representative of UKMT with the Association Kangourou sans Frontières and played a large role in bringing the Kangaroo papers to a UKMT audience every year. He died in 2019.

Kangaroo origins

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.

Contributing to our work

As a charity, we do not make a profit from entry fees. We spend all the money we raise on advancing the education of young people in mathematics. If you would like to support us further then please consider making a donation.

Our volunteers are at the heart of everything UKMT does, from creating the Challenges to running our Enrichment activities. If you would like to find out more about volunteering with us please do get in touch.
