Background and Aim

During this global pandemic period we witness, students and teachers are forced to shift to the online learning system.

This makes it hard for both teachers and their students to focus and keep motivated. Furthermore, many international competitions and Olympiads face postponements or even cancellations in the time where we need even more of these events. International Math Challenge (IMC) is a competition which has been held for nine years and hosted many brilliant international students from all around the globe to compete in Thailand. IMC IX in early 2020 was participated by more than 900 students from 60 schools in 17 countries.

Aiming to encourage students to study and excel in math and critical thinking, and also to keep both teachers and students motivated in this hard times, we decided to have an online version of International Math Challenge which will be held on 8-9 October, 2020. This event is hoped to motivate students 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.
