About us

Math4Everyone is a non-profit organization

Our Organization View For The Students

Young children have lively curiosity from the start. We strive to make the most of this natural quality by enabling them to explore passionately in the world of math. We strive to deepen and strengthen children’s math skills by providing them with the healthy and fun learning environment possible.

Who We Are

We are a group of North Bay area high school kids. We have a strong enthusiasm for math. For kids of all skill levels, our mission is to foster a love of and success in arithmetic. We think a team-based math tournament would be an entertaining and interesting approach to accomplish this.

What We Offer

We hold weekly coaching sessions in person. The coaching focuses on encouraging hands-on learning and peer collaboration. Students with all math levels are welcome to join the league. Practices and competition questions are carefully designed to meet the development needs of students with various math skills.   The main purpose of the league is not to select top math students, but instead, to inspire love and passion for math in every young student. Meanwhile, we will also be happy to provide support for students who’d like to pursue further from this league.
