Lily Wang, Center Admin

Through a math-centered after school club at a local middle school, Lily discovered the incredible potential of personalized mathematics coaching to inspire curiosity and creativity in the developing mind. She witnessed how verbal explanations coupled with games and problem solving have the power to debunk the learned helplessness attitude, distilling confidence while creating learning material that’s both academic and enjoyable. As an adult, she wants to share this life-changing treasure with others.

Mathnasium helps her do precisely this. For Lily, the most rewarding part of working at Mathnasium is seeing the spark in students’ eyes as they earned their “ah-ha” moments after tackling a challenging concept. Lily is most proud of the Mathnasium teaching philosophy of guiding students to master the reasoning behind complex mathematical concepts and theorems - instead of blindly memorizing - as this ability to summarize the fundamentals of seemingly perplexing abstractions can empower students both within and beyond the field of mathematics.
