General Information

Imagine Math is a day of mathematical activities, exploration and inquiry designed for high school mathematics teachers and students. In previous years, participants have explored non-Euclidean geometries, the mathematics of voting, and graph theory. This year, we will collect, explore and analyze data.

"[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. It's also not just for "math whizzes"--anyone who wants to learn more math can participate.

"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 Day is hosted by the Department of Mathematics at Harvey Mudd College, and is made possible by funding from Math for America Los Angeles.


Imagine Math will take place on Saturday, April 7, 2018, from 9:30 a.m. to 3 p.m. at the Green Room in the Platt Campus Center at Harvey Mudd College.

9:30 - 10:00 a.m. Registration and refreshments
10:00 a.m. - noon Session 1: Introductory explorations
noon - 1 p.m. Lunch
1:00 - 2:30 p.m. Session 2: Open-ended exploration
(Teachers meet separately)
2:30 - 3:00 p.m. Gallery walk and closing

Frequently Asked Questions

Q: What mathematics background is required for participants?
A: It might help for students to have a little experience with geometry, but anyone with an inquisitive mind will be well equipped to participate.

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 2, 2018.

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 calculator, you might want to bring them along.

Q: What about transportation?
A: Teachers and parents are on their own to organize permission slips and transportation. There is plenty of free parking along Foothill Blvd.

If you have any further questions, please email Darryl Yong at


There is no cost to attend, but registration is required as space is limited and lunch is being served.

The deadline for online registration is Monday, April 2. Teachers should use the following Eventbrite form to register for the conference.

To allow the maximum number of people to attend, if you need to decrease the number of seats you are reserving, please cancel your Eventbrite tickets and re-register. This will also allow us to have an accurate head count for lunch.


The event will take place in the Green Room in the Platt Campus Center at Harvey Mudd College. Free parking is available along Foothill Blvd.
