Public Engagement

outreachThe IGL is committed to public engagement and mathematical education. Our passion for mathematics extends beyond the walls of the classroom through our community activities like Science at the Market, Leal Science Night, Champaign Urbana Schools Foundation Freshman Focus, and various open houses. We have a vested interest in the education of students in our community schools. We organize classroom visits and field trips to our lab for students from preschool to high school.

If you are a teacher or program coordinator and would like your students to experience what over 500 students from over a dozen community schools, or you would like to the IGL to participate in a community event, then please contact

Spring 2017

Tessellation Celebration flyerDuring Spring 2017 semester our theme is tilings. We have two different activities, which we will adapt to the age group. Each activity takes an hour. Teachers can request field trips by completing the form at

Activity A: Regular Tesselations

In the first part of this activity, students will use blocks and magnetic puzzle pieces to figure out which regular polygons you can use to tile the plane. In the remaining time, students will explore semiregular tilings and create their own artwork to take home. Reference:

Activity B: Conway's Criterion

In this activity, students will consider a set of tiles and try to establish a test to tell when a tile will tile the plane via translations only. In the remaining time, students will creare their own tiles and make tesselation artwork to take home.

Mathematical galleries

We welcome you to take a look at the projects completed by IGL teams, as well as the mathematical galleries below.

Paul Nylander's Website: A collection of physics and mathematics visualizations, as well as other things of interest.

David Dumas's Website: A collection of images and videos demonstrating ideas in current research on hyperbolic geometry.

Mathematical Models: a website dedicated to the hundreds of mathematical models designed in the 19th and early 20th centuries and housed in Altgeld Hall.
