The competition starts at 7.00pm; doors open at 6.30pm.
Please do not ask teams to arrive before this time, as entry is not permitted.
Teacher markers to be present by 6.30pm please.
There is no restriction on spectator numbers. Family and friends are all welcome.
Cushions and warm clothing are recommended for spectators.
Before the Evening
Schools select 4 pupils per team and up to 2 teams per level. NOTE: All team members must be from the same school
All Teams are to have a teacher marker
Teachers need to go through the rules with each team and ensure they have a calculator on the night. Bags & paper will NOT be allowed on the stadium floor.
Each competition consists of 20 questions and lasts for 30 minutes.
More than one calculator per team is allowed. Graphic calculators are permitted.
5 marks are awarded for each correctly answered question. No marks are awarded or deducted for incorrect or incomplete questions.
A team may pass on any question they cannot solve EXCEPT the first question. The first question is multi-choice and must be answered correctly in order to continue.
Some questions may consist of more than one part and all parts must be answered correctly to get the 5 points.
If only one part is incorrect the marker will only say “No, this is not correct” – they will not specify which part of the question is wrong. Thus all parts will need to be checked by the team.
The winning team is the first to gain an absolute score of 100 points or the team which has gained the highest score at the end of 30 minutes.
If two or more teams reach 100 points at the same time or have equal scores at the end of 30 minutes, then a tie-break question is given to the teams. The first team presenting the correct answer will be declared the winner.
The answer sheets of all place-getters will be check-marked before final placings are confirmed. Teams will be given the opportunity to verify their scores.
If there is any dispute the decision of the CASIO MATHEX co-ordinator will be FINAL.
Students are encouraged to be neatly dressed and, if possible, wearing their school uniform.
The runner must wear running shoes – non marking gym shoes are best.
Teams who change runners, or whose runners do not complete the full circuit will be automatically DISQUALIFIED.
During the Competition
Teams must answer question one correctly to continue. Question one is a multi-choice question. Teams may pass any question after question one.
Runners may not talk to their marker – all answers must be written in the answer space on the question sheet. All digits should be clearly written and any old answers crossed out. Markers will only consider one answer at a time.
Some questions may consist of more than one part, and so all parts must be answered correctly to get the 5 points. If only one part is incorrect the marker will only say “No, this is not correct” – they will not specify which part of the question is wrong. Thus all parts will need to be checked by the team.
If the answer is correct the marker will give the runner the next question, otherwise the runner can pass or go back to their team to reconsider their answer.
At the end of the competition
Teams to remain seated until asked to move.
On leaving teams are to take all working papers and the Mathex pen with them.
If there is any dispute the decision of the CASIO MATHEX co-ordinator will be FINAL
