COBIS Mangahigh Maths Challenge 2019

Monday 18 - Friday 29 November 2019


Register Your School FOR OUR 2019 Competition 

The Challenge 

Across twelve days, students in COBIS Schools across the world will compete with each other in the challenge to become a maths ninja. Using online platform Mangahigh, students complete maths activities to score individual points, which in turn contributes to their school’s tally.

Students can access the activities at home or in school, so the Challenge can be used for homework, revision, or a fun task. It can also be accessed on any device with an internet connection, so via a laptop, tablet or smartphone.

Lessons are automatically assigned to students based on their age, so it's very simple to get started. Teachers can also assign activities to personalise their students’ learning experience over the Challenge period.

Competition Dates

The competition will take place between Monday 18 November - Friday 29 November 2019

Free access to Mangahigh begins Monday 4 November 2019, this allows students to practice using the platform before the competition. 

The winning school will be announced by Monday 2 December 2019.


COBIS is excited to announce that the number of school prizes has doubled this year. For the 2019 competition, there will be two leaderboards; the main leaderboard, and one for smaller schools under 500 students.

The top five schools with the highest number of points on each leaderboard will each receive an Amazon voucher. The school in first place will be awarded US $500 and an engraved trophy, second place will receive US $300 and third to fifth will receive US $200.

All students who individually earn more than 200 points, will be sent a gold medal.
