Learning How to Think in Mathematics


DEEP MATH EXPERTISE

Our math classes and math tutoring are provided by Kyla, a Master of Math, published Mathematician, and data scientist with 15 years of experience developing engaging curriculum and supporting students to become advanced math students and thrive.

INQUIRY-BASED LEARNING

We start with problems, not procedures. We help students learn how to think, adapt, and find their next move when the path isn’t obvious.

PERSONALIZED COACHING

Our math classes and math tutoring are fully customized to the evolving needs of the individual or group.

PROVEN RESULTS

Students regularly place into advanced math tracks and earn A’s. They become leaders in class discussions. They are consistently accepted to top choice high schools including The Branson School, Marin Academy, The Nueva School, and Phillips Andover Academy, and often begin in 3rd year honors math.

CONFIDENCE & JOY

We offer a joyful environment for students to explore mathematics. Through extensive experience mentoring girls, we create a supportive and empowering environment that ensures every student sees themselves as a competent problem solver or even a future STEM leader.
