Starting October 4th, Metroplex Math Circle lectures will take place from 2:00 to 4:00. We are hoping that the new 2 hour time will produce fewer conflicts with the busy weekend activities of our many students. Because the length of the lectures has been reduced we urge everyone to arrive for a prompt start at 2:00.
After 4:00, students may want to spend some time talking with one another or asking questions of our speakers. Parents might also use this informal time for discussion of the Math Circle or other relevant topics.

I think this is a good idea to limit it to two hours, although my 9 year-old reacted with slight disappointment at not having a full three hour Math lecture (!), which I think speaks well of the quality of the lectures we have seen.
