K-12 girls spent the day doing a variety of math-related activities Sunday at the Greenwich Girls Math Festival at Greenwich Academy.

Girls explored more than 20 interactive stations with different math and STEM games at the Julia Robinson Math Festival.

Students also participated in the "math playground" and listened to a keynote speech from Chrissy Newell, the co-founder of #MathGals, which aims to raise awareness and opportunity for women in mathematics.
