To inspire girls through the beauty of mathematics, giving them the confidence to pursue STEM careers
To provide the resources needed to ignite a passion for analytical, creative thought and to excel in local math competitions
To build a positive, passionate community around mathematics
AREAS OF EXPERTISE
GLeaM's founder, Catherine Cossaboom, a rising senior in high school, is the sole leader of all events, articles, and curricula through this program. She has been extremely passionate about math from an early age. She is a member of Georgia's state math team, Georgia ARML, an alum of the prestigious MathPrize for Girls competition at MIT, and a successful participant in the MathCounts and MAA competitions. She is a three-year captain of her high school's math team, leading her team to straight 5A state championships. She attended Georgia's Governor's Honors Program (GHP) in 2019 as a math major and is looking forward to participating in the prestigious Ross summer program in 2020.
GLeaM focuses on exciting areas of more discrete fields of math not taught in schools, such as number theory and combinatorics, as well as prep for middle and high school competitions, such as AMC and MathCounts.
Catherine sees math as empowering and beautiful, and she loves to share that passion with members of GLeaM.
Note: Although this site is geared towards girls and the majority of members are girls, everybody, including boys, is allowed to join GLeaM as long as they are respectful and support the community, and we welcome all members!
GLeaM's website guides members through a variety of resources, including competition-related websites,
listings of opportunities around Atlanta (and the nation!) and links to exciting topics in various fields of math. This creates an immersive experience for members and helps them to grow their knowledge and passion for STEM fields.

Every week, an article will be uploaded about fascinating fields of math, as well as tips as to how to improve your math game, including prep for local and national competitions.
A friendly server accessible for comments allows us to discuss the material and provide enrichment and puzzles for all types of puzzle lovers.
You can expect a new post by each Sunday at 5 pm.

AN INNOVATIVE COMMUNITY
Each member of the GLeaM community has access to the forum, where they can post ideas, questions, stories... anything they want to discuss with the community. In this way, we can also gather feedback to better curb the program to our members and their interests.
You can sign up to become a member in the top righthand corner.

Occasional scheduled events will occur, where we can delve further into an area of interest or into prep for MathCounts if so desired. They will either occur through the online Zoom platform or in a venue around Atlanta. The event information will be posted well in advance to the forum.

OUR LOGO STORY
The great mathematician Maryam Mirzakhani's family often described the way she worked as "painting," as she crouched on the floor drawing on large sheets of paper. Mirzakhani was the first woman to win the Fields Medal, a prestigious award that is the equivalent of the Nobel Prize for math. She was a major advocate for women in mathematics, and she died in 2017 of breast cancer. The paintbrush is a symbol of her, but also of the beauty of mathematics, closely intertwined with art in the way ideas transition marvelously into one another. Around the paintbrush is a fractal, the Sierpinski triangle, one of the most beautiful aspects of math, reminding us to pursue seemingly impossible dreams in surprising fractional dimensions.
“Pure mathematics is, in its way, the poetry of logical ideas.”
