On March14, 2022, we celebrated The International Day of Mathematics with a variety of activities. Our students donated their income from selling Pi-themed foods they brought from home throughout the day to be used in our school's CAS events. In addition, our students, who showed their talents in the fields of ceramics and painting, created works with the theme of mathematics and pi. The afternoon parts of the events were held by guest speakers. Three female mathematicians who are experts in their fields gave speeches under the title of ''Women Mathematicians.'' We would like to thank Prof. Dr. To Betül TANBAY, Prof. Dr. Ayşe BERKMAN, and Prof. Dr. Selda KÜÇÜKÇİFÇİ GÜLLÜ for their time and contributions.
