Background and Aim
The first Math Challenge was organized in 2012 as an inter-school competition among international schools in Bangkok with the participation of 144 students from 10 schools. Gradually the number of participants increased, and in 2014 Math Challenge went beyond the Thailand borders and started hosting international participants.
In 2020, aiming to encourage students to study and excel in math and critical thinking, IMC team decided to conduct an online version of International Math Challenge to boost the motivation of both teachers and students who have been bored, lost goal-oriented character and stimulus for study under this difficult global pandemic times, when most of the Olympiads and competitions are forced to be cancelled or postponed until unknown time.
Each participating school may organize their students in each category i.e. grades 1-2, grades 3-4, grades 5-6, grades 7-8 and grades 9-10, and grades 11-12. This is an individual competition in which students can receive prizes for their personal achievement. The competition will be conducted in five languages, namely English, Thai, Chinese, Russian and Spanish, where students are expected to solve 40 multiple choice questions in 90 minutes. For the kids’ category (grade 1 and 2) 25 questions and 60 minutes. This event is hoped to motivate students to see math in a different light, have their interest stimulated in the subject and think how they can apply math in their future studies and daily life.
