General Information

Imagine Math is a day of mathematical activities, exploration and inquiry designed for high school mathematics teachers and students. Participants in the 2006 Imagine Math Day explored graph theory and graph complexity; this year, we will explore non-Euclidean geometries.

"[This activity] reminded me how enjoyable math can be for students. Sometimes, we teachers get caught up on covering all the material and not taking the time to let students experience and live the math."
-- from a teacher attending the 2006 Imagine Math Day

Imagine Math Day is not a contest--it's a time for students and teachers to investigate and explore mathematics just for the sheer enjoyment of it.

"Math is usually considered something with one right answer, but [I see now that] there is room for interpretation."
"[I learned] there's more to math than memorizing quadratic formula [sic]. It showed math isn't just formulas, but you need to think."
-- from students attending the 2006 Imagine Math Day

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 21, 2007, from 9:30 a.m. to 3 p.m. at Platt Campus Center at Harvey Mudd College.

Frequently Asked Questions

Q: What mathematics background is required for participants?
A: Participants do not need any prior experience on the subject of non-Euclidean geometry, but to get the most out of this activity, they should be familiar with plane geometry and have some experience with geometric constructions. Advanced high school students who are good at mathematical reasoning and students with an interest in mathematics are likely to benefit most from attending.

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 Monday, April 9, 2007.

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, straightedge, compass, protractor, pencils, color markers, and calculator, 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.
