General Information

Imagine Math is a day of mathematical activities, exploration and inquiry designed for high school mathematics teachers and students, centered around an area of cutting-edge mathematics research. This year’s theme is graph theory and graph complexity.

Imagine Math is hosted by the Department of Mathematics at Harvey Mudd College, and is made possible by funding from the IAS/Park City Mathematics Institute. The event is being organized by the Harvey Mudd College Professional Development and Outreach Group, which is directed by Darryl Yong.


Imagine Math will take place on Saturday, April 22, 2006, from 9:30 a.m. to 3 p.m. at Platt Campus Center at Harvey Mudd College.

9:30 - 10:00 a.m. Registration and refreshments
10:00 a.m. - noon Session 1: Introduction to graph theory and graph complexity
noon - 1 p.m. Lunch at Hoch-Shanahan Dining Hall (Aviation Room)
1:00 - 2:30 p.m. Session 2: Open-ended exploration
(Teachers meet with Michael Orrison)
2:30 - 3:00 p.m. Gallery walk and closing

During the first session from 10 a.m. to noon, students and teachers will explore graph theory through various applications of graphs. We will learn enough graph theory together so that everyone will be able to participate in the main activity of the day, that of developing and exploring different notions of graph complexity. Students will get a chance to develop their ideas further during the second session after lunch and create posters explaining their ideas that will be viewed by all during the gallery walk at 2:30 p.m.

Frequently Asked Questions

Q: What mathematics background is required for participants?
A: No prior experience with graph theory is required, and there are no specific math subject prerequisites. However, advanced high school students who are good at mathematical reasoning and students with an interest in mathematics are likely to benefit most from attending. Those students with an insatiable curiosity are encouraged to visit this gallery of graphs or the entries on graph theory at wikipedia.

Q: How much does it cost to attend Imagine Math Day?
A: There is no cost to attend and lunch will be provided to all participants. However, participants must register by April 10, 2006.

Q: Do we have to attend both sessions?
A: Yes. The two sessions build on each other, so it is not possible for participants to attend the afternoon session without the attending the morning session.

Q: What do we need to bring?
A: Most importantly, bring your enthusiasm, energy and an open mind for a day of fun and interesting mathematics! Materials and supplies will be provided, but if you prefer to use your own paper, pencils, color markers, and calculators, you might want to bring them along.

About Harvey Mudd College

Harvey Mudd College is a private, liberal arts undergraduate institution of science, engineering and mathematics. The college enrolls about 700 students of high ability; approximately one third of them are National Merit Finalists and one quarter are high school valedictorians. HMC is a member of the Claremont College consortium, which includes four other undergraduate colleges (Pomona, Claremont McKenna, Scripps, Pitzer) and two graduate institutions (Claremont Graduate University and Keck Graduate Institute), forming an academic community of about 5000 students.

The Department of Mathematics at Harvey Mudd College recently received the 2006 Award for an Exemplary Program or Achievement in a Mathematics Department from the American Mathematical Society. Each year, the math department graduates roughly 40 students who do and go on to do amazing things. More than half of HMC math graduates go on to graduate school.
