Providing an additional opportunity for problem solving

The Grey Kangaroo is a follow-on round to the Intermediate Mathematical Challenge. It is a 60-minute, multiple-choice Challenge consisting of 25 problems.

We invite several thousand qualifying UK-based students from the Intermediate Mathematical Challenge to take part in the Grey Kangaroo. Entry to the Challenge is by invitation only and is based on a qualifying score, which is variable from year to year.

Date: Thursday 16th March 2023

Eligible year groups: England and Wales - Year 9 and below, Scotland - S2 or below, Northern Ireland - Year 10 or below

Time allowed: 60 minutes

Entry fee: Free invitation or £4 per discretionary entry

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

Entry deadline: You can now place paper and online orders right up to the day of the Kangaroo, including on the day itself. You just need to make sure you leave yourself enough time to pre-populate, download and print your answer sheets and question papers (paper orders only).

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 Grey Kangaroo will be clearly indicated in your results from the Intermediate Mathematical Challenge. Invitees will receive automatic online access to the Challenge but there will also be an option to receive a paper version.

Managing entries

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

If your students are sitting the Grey 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 Grey 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 Grey 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 Grey Kangaroo are as follows:

  • 5 marks are awarded for each correct answer to questions 1 - 15
  • 6 marks are awarded for each correct answer to questions 16 - 25
  • In the Grey Kangaroo you will NOT lose marks for getting questions wrong
  • Answers left blank will be marked as 0

Awards

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

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

The 2022 award thresholds were:

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.
