There are many other math contests available. Most of them are local or at a smaller scale. Here are a few examples, Math Olympiad for Elementary and Middle Schools, Math League contests organized by different organizations, Orange County Math Field Day for elementary school students, Bay Area Math Olympiad. There are Math Field Days in other areas as well. In recent years, students from some top universities are organizing math contests regionally. Successful examples include Harvard MIT Math Tournament (HMMT), Princeton University Math Competition (PUMaC), Cal Tech / Harvey Mudd Math Competition (CHMMC), Stanford Math Tournament.
We are compiling a comprehensive list of them for your reference. Please check back later. You are welcome to submit one that you know. Comments about your experience with it would be appreciated. We encourage our students to participate in math competitions to get exposed to different types of problems, appreciate and gain interest in intelligent activities, and make friends with peers who share the same interest. However, we also stress to our students that it's important to build a solid foundation in mathematical thinking, analytical and logical thinking skills through a systematic training approach. A good performance in any math contests will come naturally. Math contests will eventually fade away from your life. The skills you learned from the experiences will stay with you and will help you to grasp the opportunities that are presented to you.
