Math Discovery

(in person)

The sessions below are all in-person.  Click here for online student sessions.

Don’t miss the chance to join one of MoMath’s specially trained educators in Math Discovery, a series of hands-on classes exploring intriguing math topics.  For students and their families/caregivers.  Limited space available.

Upcoming Sessions

“Secrets of Telling Secrets” (Grades 3–6)

Friday, September 22 at 4:15 pm

Explore cryptography, secret codes, and ciphers.  Join us for this introduction to the substitution cipher, which hides messages by replacing letters or groups of letters with other letters or groups of letters.  Using patterns and perseverance, learn how to create hidden messages — and how to break secret codes!   For students in grades 3 through 6 and their families/caregivers.


Tessellation Station” (Grades K–2)

Saturday, September 23 at 2:30 pm

From nature to art to architecture, tessellations — or tiling patterns — offer a creative way to understand geometry.  Using the symmetries of polygons, discover surprising and beautiful patterns as you learn about infinite tessellations.  For students in grades K through 2 and their families/caregivers.


“From Prussia, with Math!” (Grades K–2)

Saturday, September 23 at 4:00 pm

Discover the mathematics of constructing paths on graphs in this introduction to graph theory.  Find out what bridges in 18th-century Prussia have to do with graph theory, while tackling classical problems and problems that remain unsolved today!  For students in grades 5 through 8 and their families/caregivers.


“Shape Shifters” (Grades pre-K–2)

Sunday, September 24 at 10:15 am

Shapes are all around us and form the basic building blocks of modern life.  Using wooden squares, rectangles, rhombi, trapezoids, and hexagons, discover how shapes are different from each other and how mathematicians identify and name them.  Through games and interactive activities, explore geometrical symmetries and how to construct polygons with many sides, including the tetracontakaihexagon!  For students in grades pre-K through 2 and their families/caregivers.


“Möbius Madness” (Grades 3–6)

Sunday, September 24 at 4:00 pm

Join us to construct fascinating topological objects such as Möbius bands, discovering their fundamental patterns and structures.  Through hands-on activities, uncover the surprising properties hidden around every twist and turn!  For students in grades 3 through 6 and their families/caregivers.



All Math Discovery sessions starting between 10:00 am and 4:00 pm will carry an event fee that allows you to attend a specific 45-minute Math Discovery session and provides you with Museum general admission for entry between 10:00 am and 5:00 pm on the same day as the registered event.

All Math Discovery sessions beginning at or after 4:00 pm will carry a fee of only the event ticket; general admission is not included.  To explore the Museum prior to the start of your session, general admission must be purchased separately, either online at or in person with a ticketing agent or at a kiosk.

If you are a MoMath member, you are eligible for membership pricing that waives the admission fee; please email to register with member pricing.  Please note that Math Discovery events starting at or after 4:00 pm do not include general admission fees.

Registration and supervision

All children 16 years of age or younger must be accompanied by an adult, and all participants (children and adults) must be registered to attend.

Refund policy

Strictly no refunds, no credits, and no transfers will be permitted.  Spots are limited and available on a first-come, first-served basis.
