Global Math Challenge (GMC) is a worldwide math competition held online and hosted by Sony Global Education, Inc.
Join thousands of math fans from across the world in a contest packed full of fun brainteasers and logic puzzles. Easy to register, easy to organize, but a challenge to become a global champion.
A challenge of intelligence and your intuition.
Mind stretching puzzles developed by The Japan Prime Math Olympic Committee help to encourage students to take a logical, flexible approach to math. These beautifully illustrated, engaging questions will bring out the mathematical curiosity in your students no matter what curriculum they study.
Discover unknown strengths and weaknesses.
After the challenge, students can check on their strong points with the GMC Review, giving them encouragement and actionable advice on how to improve their technique, as part of the GMC 5 Thinking Strategies. These skills can be used outside of math class too - with science, programming and computational thinking all benefiting from a strong footing in math fundamentals.
Goes beyond just questions & answers.
We provide a full graphical analysis of the results of your class and school, including rankings and average scores. You can also enjoy a breakdown of how each challenger approached each problem. All questions also come complete with easy to understand, step by step explanations. By reviewing their answers after the challenge, every student can walk away with a new found confidence in their math skills.
