The 2025 AIM Math Fair was held on Saturday June 28 on the lawns surrounding Caltech Hall on the Caltech campus.

More than 700 gathered to learn new mathematical games, tackle challenging puzzles, and participate in large-scale collaborative construction projects.  “It was a day of celebrating the joy and the variety of mathematics,” said AIM director Brian Conrey.

Activities ranging from the math- and science-themed Story Corner for young children to challenging puzzles and games for children and adults of all ages kept participants engaged throughout the event.
