Each WMC Qualifying competition currently has 9 assessed rounds. These are:

Purpose |
To help build life-long friendships and respect diversity |

Duration |
Within the Opening welcome |

Style |
Introduction and mathematical activities usually associated with the culture of the host venue and country. |

Purpose |
To test one’s mathematical knowledge and skills in a conventional, yet challenging way. |

Duration |
1.5 hours |

Style |
A traditional multi-choice response examination paper. |

Nature of submission |
Write the choice on an answer sheet. |

Notes |
Simple marking: 1 for correct, 0 for incorrect |

Purpose |
To inspire strategic thinking to win a quick 1v1 mathematical game. |

Duration |
Heats: About 1 hour Finals: Instant knockout |

Style |
Participants face each other 1v1 in a short game. Students may face multiple opponents. Subtle rule changes may happen at any time. |

Nature of submission |
After each duel, 3 stickers are awarded for a win, 1 for a draw and 0 for a loss. The finals is an instant knockout. |

Purpose |
To spark one's creativity when asked to find mathematical patterns from limited data. |

Duration |
Heats: About 1 hour Finals: Spectator sport featuring the better performers in the heats |

Style |
For each code, two data pairs are projected in sight. The next data pair will have one of its values missing, and participants must identify this missing value. If correct, they receive a sticker and it is then revealed on screen. This process is repeated for each code. Codes could be mathematical or abstract. |

Nature of submission |
Heats: Write the missing value on a grid within the time limit. One sticker is awarded immediately for each correct answer. Finals: Finalists are positioned in a horseshoe shape facing a projected screen. In turn, they have to quickly say out loud the next data value. If correct, a sticker is awarded. If not, the next participant attempts the same one. |

Notes |
The number of stickers determine a participants ranking. |

Purpose |
To enhance one’s conceptual knowledge under timed pressure. |

Duration |
About 1 hour |

Style |
Teams sit as a pair and as a single opposite each other. There are 12 questions in total. After a set of 4 questions, the team members rotate once, so all experience being in every position. Each question has 3 stages: stage C requires a result from stage B which requires a result from stage A. Stage A and C are answered by the pair and stage B is answer by the single. So within each question, the answer of stage A is passed to the single who uses it and then passes the answer of stage B back to the pair to answer stage C. Only positions A and C may verbally communicate with each other. Although teams are allowed to send back answers they think are incorrect, this is not common. |

Nature of submission |
Answers to stage A and B contribute towards the solution obtained after stage C, which is then held in the air as a final submission. |

Notes |
Correct answers from Stages A, B and C are worth 2, 3, and 4 points each respectively. |

Purpose |
To combine strategic thinking with communication skills when answering maths questions as quickly as possible. |

Duration |
About 1 hour |

Style |
Each team has a desk within a large loop around the space, and 12 questions. There are 4 stations, each with 3 postboxes, spread evenly around the loop. Teams can choose to answer any question, and a runner deposits agreed solutions into the appropriate postbox by following the loop in a particular direction. This is repeated after half time with another set of 12 questions, and the runners direction around the loop is reversed to ensure fairness. |

Nature of submission |
Solutions are written on their corresponding question papers and must be deposited upside down in the correct postbox. |

Notes |
Earlier correct deposits are awarded more points than later ones. Incorrect solutions receive zero points. Teams are not expected to answer all questions in the time allotted. |

Purpose |
To encourage creativity when presenting broader mathematical concepts through a given stimulus. |

Duration |
Session 1: Planning and creation Session 2: Presenting |

Style |
The stimulus is used to explore mathematics creatively. Participants then present their findings in an engaging and interesting way. |

Nature of submission |
A presentation, to a few other teams and an adjudicator, lasting no more than 3 minutes. |

Notes |
Emphasis is on good mathematical understanding and processes being clearly presented through any medium - video, drama, documentary, slideshow… |

Criteria |

Appropriate terminology used Appropriate written notation Accurate and correct mathematics Limitations acknowledged |
Aesthetically pleasing Humour Engaging Understandable message Concise - within 2 minutes |

Purpose |
To demonstrate knowledge through collaboration by solving mathematical problems in a sequential, fun and lively atmosphere. |

Duration |
About 1 hour |

Style |
Each team is allocated a desk within a column of desks. A runner goes to the back of their column and back again to collect a question and then completes the lap back to their team. When a solution is written on the question paper, the runner returns along the same route for marking. |

Nature of submission |
Solutions are written on the question sheet. If it is correct, they earn points and receive the next question. Otherwise, they must return to their table. The runner may pass on a question instead of checking a solution in the same lap. Teams on the same points with fewer passes will be ranked higher. |

Notes |
Once a question is passed, participants may not return to it. |

Purpose |
To apply strategic problem-solving to a real-world context. |

Duration |
About 2 hours |

Style |
Each team is given a practical problem, and provided the same set of resources and equipment to address it. Making calculations are an essential part of the process. |

Nature of submission |
Teams will create a model to solve their problem. When the time is up, each model will be tested, resulting in a distance or time measurement. |

Purpose |
To develop ingenuity while solving divergent, limited data problems. |

Duration |
Within 1 hour |

Style |
Each team creates a poster responding to a specified problem. |

Nature of submission |
The poster is aesthetically pleasing, with a clearly articulated understanding of mathematical knowledge and processes. |

Notes |
The emphasis is on how thought processes are communicated on paper. |

Descriptor |

Overall aesthetic appeal Clarity Concise Originality Easy to understand/follow Asking or analysis "What if..." Expansion or generalisation Appropriate mathematics Excellent mathematics Accuracy of answer considered Understanding limitations |

The WMC Senior and Junior Finals currently have these aditional 3 assessed rounds. These are:

Purpose |
To cooperate in using mathematical knowledge to produce rigourous mathemaical proofs. |

Duration |
About 1 hour |

Style |
Working at a large wipe board within a University faculty room, team members provide a mathematical proof for each of the statements provided. |

Nature of submission |
Written proofs on a wipe board can receive up to 4 marks each: 4 : Complete, concise and well explained 3: Complete, but inconcise or not well explained 2: Good progress made, a crucial step (or a few minor ones) missing 1: An appropriate attempt made 0: Nothing relevant enough |

Notes |
Teams may return to a previously incomplete proof at any time. Adjudicators circulate and mark each proof before the team wipe it from the board. The proofs include a range of topics from within the themes of learning: Algebra, Geometry, Number theory, Statistics, Calculus. |

Purpose |
To cooperate with others in strategising solving cipher codes. |

Duration |
About 1.5 hours |

Style |
Teams are set-up in a similar way as for Lightning. They choose ciphers to solve from a 4 by 5 rectangular grid. When deciphered correctly, a simple mathematical question is revealed which must be answered. |

Nature of submission |
The runner chooses which of the 20 ciphers to solve first and returns with their answer written on the question paper. If correct they are awarded a mark in that cell, if incorrect an X is awarded and they cannot attempt that cipher again. The runner selects another available cipher. |

Notes |
Teams are issued with the same initial cipher. After this, the number of copies of each of the 20 ciphers is fewer than the number of teams; first-come first served. The scoring is as follows: For every row and column, sum the (number of continuous solved ciphers) ^{2}. |

Purpose |
To creatively use and manipulate big data in such a way to make predictions about an issue of global significance. |

Duration |
About 2 hours |

Style |
Using a computer with a spreadsheet of data. |

Nature of submission |
On paper showing what data manipulation was carried out to arrive at the prediction. |
