Preparing for the challenge
We are delighted to be working with Dr Frost Maths to help teachers use UKMT past papers and problems in the classroom.
You can utilise UKMT past papers, solutions and investigations as preparation materials for your students. They are a great resource containing high-quality problems from previous years designed to encourage mathematical thinking.
Instructions
Questions 2 and 3 require answers only. The spaces for answers are clearly indicated on the answer sheets.
Questions 1, 4 and 5 require full written explanations. If your solution involves calculations, equations, tables, etc., explain where these come from and how you are using them. Explain how the steps of your solution link together, and give full proofs of assertions that you make. Answers alone will gain few marks (if any).
Partial marks may be awarded for good ideas, so try to hand in everything that documents your thinking on the problem — the more clearly written the better. However, one complete solution will gain more credit than several unfinished attempts.
Earlier questions tend to be easier. Questions have multiple parts. Often earlier parts introduce results or ideas useful in solving later parts of the problem.
The use of rulers and compasses is allowed, but calculators and protractors are forbidden.
You may use rough paper to note down your ideas, but you should write up your solution on the answer sheet provided for each question.
