Math Day at the Beach 2024

On March 23, 2024, the 23rd Math Day at the Beach event was hosted on the California State University, Long Beach campus. Math Day at the Beach is a problem-solving festival for Southern California high school students who want to have fun with mathematics and enjoy a day of camaraderie with university mathematics students and professors.

A total of 34 teams of six high school students each participated in this event, 5 teams in Division A and the others in Division B.

This year's event was hosted on the campus and it was an unequivocal success. There were several parts to this event: an individual round, team round, relay, presentation by an invited speaker, teachers face-off round, and the face-off round to determine individual winners. The problems were designed by the Mathematics and Statistics Department faculty and were selected from algebra, geometry, trigonometry, number theory, combinatorics, and probability.

About Math Day at the Beach

This annual event was started in 2000 by the Department of Mathematics and Statistics under the directorship of Dr. Kent Merryfield, a charismatic leader with unparalleled expertise in high-school math competitions, and ran uninterrupted until Dr. Merryfield's untimely death in November of 2018.

In March 2019, the 20th Math Day at the Beach took place under the new directorship of Dr. Olga Korosteleva. Then the pandemic placed this event on hold for two years. The event returned on March 12, 2022, and has been held since.

Math Day at the Beach is completely free, thanks to our generous sponsors, the Jerry Cassaday Family and LBS Financial Credit Union.
