About QuantiMath

Who We Are

QuantiMath is an online applied math workshop for middle school girls, featuring seasonal lesson series, an annual math modeling competition, and a monthly newsletter. Our goal is to encourage interest in STEM by showing how math shapes the world around us, introducing students to foundational topics in applied mathematics, and creating a community where girls can think, explore, and collaborate freely.

This year, we offer four online lesson series, two in the fall and two in the winter. In the spring, students can showcase their skills in our annual math modeling competition, an asynchronous and collaborative challenge open to all experience levels. Additionally, our monthly newsletter highlights real-world applications of math, shares resources, and helps students stay connected to the QuantiMath community.


Our Mission

Women make up only 35% of STEM graduates. Female scholars earned 25% of the Doctoral Degrees in Mathematics and Computer Sciences. Statistics can paint a clear picture, but the gender gap in STEM only becomes more prevalent the closer you look.

Behind every percentage lies girls who have been excluded from discussions, isolated in class, and assumed to be less because they weren't given the chance to speak up in the first place. Gender stereotypes can take root as early as age six, bringing about self-doubt and a loss of interest in STEM that adolescents carry into adulthood and their professional careers. This pattern is perpetuated by the erasure of women in academia. The lack of representation makes eliminating the gender disparity in mathematics impossible.

Therefore, we created QuantiMath to help bridge this gap.

QuantiMath is an online applied math workshop dedicated to empowering middle school girls by sparking curiosity and cultivating confidence. Our mission is to build strong critical thinking skills, establish the connection between abstract concepts and real-world impact, and ignite a lifelong passion for discovery. Above all, we are committed to providing an inclusive, welcoming space where every girl feels encouraged to ask big questions, explore complex ideas, and develop the problem-solving skills to navigate the world of STEM.

It can often feel overwhelming to begin exploring the vast universe of mathematics, so QuantiMath is designed to be the launchpad. All workshops are free of charge and require no previous knowledge. By taking our course, you will acquire a strong foundation of skills that will aid you as you continue your mathematical journey.
