3EF Math Circle
A Research-Informed, Student-Centered Approach to Mathematical Thinking

​

The 3EF Math Circle is an enrichment program for students who are curious about mathematics—and who may learn, think, and grow in different ways.
Like other math circles at leading universities, we explore deep, engaging problems that go beyond school math. What makes the 3EF Math Circle different is how intentionally we support each learner.
We believe that meaningful learning in mathematics depends not only on problem difficulty, but also on how students think, feel, and stay motivated while learning.

​

Thoughtfully Designed Instruction
Unlike many math circles that rely on rotating volunteers or guest instructors, the 3EF Math Circle is led by a carefully selected instructional team with deep experience in mathematical problem solving and competition-based training.
Our lead instructor, Kevin Lan, has guided the 3EF Math Circle since its very first season. As a former gifted learner himself, Kevin brings both strong mathematical insight and a deep understanding of students’ emotional and motivational experiences.
His long-term leadership provides:

• A stable and supportive learning environment

• Consistent instructional vision across sessions and seasons

• Teaching that adapts to students—not the other way around

 

Learning That Sees the Whole Student
Some students enjoy fast-paced challenges.
Others think deeply and need more time.
Some feel confident. Others feel anxious—even when they are capable.
At the 3EF Math Circle, these differences are not treated as weaknesses. They are valuable signals that help us teach more effectively.

Students are encouraged to reflect on their thinking, discuss strategies, and engage with problems in ways that respect their individual learning styles.

​

A Program Connected to Educational Research
The 3EF Math Circle is part of a broader educational research initiative focused on understanding how students engage with mathematical problem solving and how learning environments can better support diverse learners.
Families who choose to participate in optional research activities—such as surveys, reflections, or assessments—help inform the design of more equitable and personalized learning experiences. Participation is always transparent and voluntary, and students benefit from more intentional, research-informed instruction.

At 3EF, math is not just about finding the right answer—it’s about understanding how students learn, grow, and build confidence through challenge.
