National Museum of Mathematics


Here are MoMath’s top holiday picks for 2021.

For math fans of all ages:

Give a gift membership to North America’s premier museum dedicated to mathematics.  MoMath memberships start at $70 and include an array of benefits, including: free admission to the Museum; exclusive invitations to members-only events; free access to MoMath’s extensive library of event recordings; free registration for select online programs; and a 10% discount at Additions, the shop at MoMath.


A one-of-a-kind gift for all ages:

Don’t miss the opportunity to gift a personalized, autographed book by New York Times best-selling author, Steven Strogatz!  Steve, Professor of Applied Mathematics from Cornell University and an award-winning mathematician, is MoMath’s 2021-2022 Distinguished Visiting Professor for the Public Dissemination of Mathematics.  Autographed copies of Infinite Powers, The Joy of X, and The Calculus of Friendship are sold exclusively at Additions, the shop at MoMath!


For your littlest mathematicians:

Q-bitz Jr. is a fun way to introduce your littlest mathematician to pattern matching, spatial reasoning, problem solving, visualization, and more.  The engaging play is easy to learn and mastering it will help improve your child’s visual perception.

Recommended Book: I Spy 123 is beautifully illustrated and entertaining for kids (and adults!).  This book promotes learning numbers and colors and can help improve concentration, vocabulary, counting skills, and attention to detail.


For beginning thinkers:

Hay Stax is a barnyard packing puzzle in which the player selects a challenge and arranges the farm animals so they all fit precisely in their pen.  The animals come in various shapes and sizes, so you’ll have to use your best spatial skills to correctly corral them together.  Get ready to herd the horse, pack the pig, and stack the sheep!

Recommended Book: Hidden Figures: The True Story of Four Black Women and the Space Race brings to life the stories of Dorothy Vaughan, Mary Jackson, Katherine Johnson, and Christine Darden — a group of four African American mathematicians, known as “human computers,” who lived through the civil rights era, the Space Race, the Cold War, and the movement for gender equality, and whose work forever changed the face of NASA and the country.


For young creators with big ideas:

Chroma Cube is a deduction puzzle that challenges solvers to use their reasoning skills.  Try to decipher the cryptic clues on any of the 25 puzzle cards to determine how the cubes should be arranged.

Recommended Book: In Eat Your Math Homework, you’ll find a collection of yummy recipes and fun math facts to tempt taste buds and make you hungry for more!  Amaze your friends with delicious Variable Pizza Pi or wash down your geometry assignment with some Milk and Tangram Cookies!


For puzzling teenagers:

Calling all mind game enthusiasts!  Reflect Mirror Mazes is a competitive game of flipped perspective.  Test and develop your own ability or compete against one another.  Using only the view seen in the mirror, can you draw the correct route through the maze to complete the challenge?  Sounds simple… but remember, when following a mirror image, nothing is as it seems!

Recommended Book: Beautifully drawn and exquisitely detailed, Prime Suspects is a rare opportunity to experience mathematics like never before.  Set off on a voyage of forensic discovery, exploring some of the most fundamental ideas in mathematics with this graphic novel.  Integers and permutations are born of different fields and analyzed with separate techniques, yet when the Mathematical Sciences Investigation team autopsies the victims of two seemingly unrelated homicides, they discover extraordinary similarities between the two cases.


For adults who love twists and turns:

Unlock the mystery of ShashiboShashibo is a mesmerizing shape-shifting puzzle box.  One cube transforms into more than 70 different shapes.  Combine two or more to build larger shapes and create more possibilities.  Can you master the shape shifting box?  Shashibo will delight adults and kids alike.

Recommended Book: 99 Variations on a Proof offers a multifaceted perspective on mathematics by demonstrating 99 different proofs of the same theorem.  With a rare blend of humor and scholarly aplomb, Philip Ording weaves these variations into an accessible and wide-ranging narrative on the nature and practice of mathematics.


For seniors with infinite ideas:

The Martin’s Menace puzzle is perfect for someone who loves a challenge.  Originally called “Four Fit,” this puzzle was renamed by its creator Stewart Coffin after Martin Gardner’s week-long efforts to solve it.  Martin Gardner (1914-2010) is considered the Father of Recreational Math with perhaps the greatest puzzle mind of the 20th century.  He called this puzzle “the finest dissection puzzle of all time.”

Recommended Book: A historical and pedagogical dimension sets The Puzzle Universe apart.  The 315 puzzles are described in extended captions that explain in easy terms the story of the puzzles’ origins and attempts to solve them, the value of puzzles to education, and the development of the mathematical sciences in light of recent research and unmet challenges.


For the chic geek:

The Gradient Puzzle provides a vibrant way to slow down and focus on color and perception.  Enjoy the slow, deliberate assembly, and notice how the tone of each piece is used to locate its proper position.  This 500-piece jigsaw puzzle is made from a thick-stock and high-quality art paper that measures 18″ x 24″ when fully assembled.


For the family that plays together:

Go head-to-head in Tyle, a colorful strategy game.  Players battle it out to move from one corner of the grid to the other by rotating, flipping, and sliding tiles to link up a path, creating their own route to victory.  Don’t just focus on creating your own route though — try defeating your opponents by blocking their path along the way!  Will you be able to find a winning strategy, or will you be left on a path to nowhere?


For your favorite teacher:

Gift your favorite teacher the Pizza Pi Cutter!  What happens when the circumference of a pizza is divided by its diameter?  Cut your pie with pi!  This pi symbol-shaped pizza cutter has two stainless steel blades for cutting power.


For anyone who loves the beauty of math:

The gyroid is a “triply periodic minimal surface” that divides all space into two congruent regions.  This beautiful bronze representation of the gyroid was created by Bathsheba Grossman using a new direct-metal printing technique, making a mathematically compelling addition to any desktop.



For when you want to show just how cool math is:

Back by popular demand, the Galton Board is math in motion, demonstrating centuries-old mathematical concepts in a modern, compact device.  It incorporates Sir Francis Galton’s illustration of the binomial distribution, which, for a large number of beads, approximates the normal distribution.  Pascal’s triangle, which is the triangular array of binomial coefficients, is also superimposed, and even the Fibonacci numbers make a surprising appearance.


For fashionable figures:

These fashionable 3D Printed Plus Earrings change shape depending on your perspective.  Together, seven wireframe cubes form a three-dimensional plus sign.  When you look at the piece directly from the front, side, and top, you see the classic plus shape.  However, this composition hides many geometric patterns including triangles and hexagons, which become apparent when you look from another angle or catch a passing shadow.
