Students welcome at Mathematics Festival

Math-loving students in grades 6-12 are invited to sign up for the Julia Robinson Mathematics Festival, taking place from 8:30 to 11:30 a.m. Jan. 27 at UC Berkeley's International House.

The challenging but noncompetitive festival is a program of the Mathematical Sciences Research Institute and named for Robinson, a longtime UC Berkeley mathematics professor.

"The festival is ideal for students who love math, games, or puzzles, for contest-goers seeking another side of math, or for those who prefer a collaborative, noncompetitive approach to problem-solving," say organizers. "At the festival, students can spend an entire morning exploring mathematical activities designed to inspire curiosity, encourage collaboration and promote creative problem-solving."

Participants spend about 20-30 minutes on each activity and get support from adult volunteers. Some problems will engage middle school students, "while others are advanced enough to challenge the brightest high school students."

There are limited spaces at the festival to allow individual attention for each student.

The cost is $10 per student and registration and details are online at https://hosted.msri.org/jrmf/2013/berkeley/register. Full and partial scholarships are available.
