MITxplore will hold its MITxplore@MIT math enrichment program for students in Grades 4-6 from October 4 through December 11.  Students will meet on Sundays, 1PM-2PM, to explore math in fun and creative ways, under the direction of MIT graduate students aiming to inspire and support their academic pursuits.  A $150 covers all expenses, including books, tools, and equipment.  Enrollment filled up very quickly (before we could post about it!), but you can sign up on the waitlist.
