"Come together. Over love in Mathematics"

There is great enthusiasm among Primary students to compete in mathematics competitions. This is an extremely good sign for the progress of mathematics education.


However, most mathematics competitions seem to be testing students' knowledge beyond the school syllabus and exposing what the students cannot do while a mathematics competition should actually be a platform to reveal what students can do!

ISMC aims to encourage the young students to compete at the international level. It also helps to identify best talents among students. Its syllabus is mainly common with the Singapore Maths (Primary) syllabus. Thus, students can take part in ISMC without advanced beyond-the-grade-level knowledge and marathon of special training trying to learn in hours all topics which are new and unfamiliar to them.

Students write their responses on an answer sheet. Questions are arranged in a way that the first ones are the easier ones, then the level of difficulty gradually increases so that the last questions are the more difficult ones. 2 marks each are contained by Questions 1-10, 4 marks each by Questions 11-20, and 6, 7, 8, 9, 10 marks each by Questions 21,

22, 23, 24, 25 respectively, making a full score of 100. If a participant leaves a question unanswered, that question will be marked '0'. There is no penalty/deduction for wrong answer.
