Our online education sessions offer several inspiring mathematical themes for grades pre-K through 12.
Shape Shifters (grades pre-K through 2): Shapes are all around us and form the basic building blocks of modern life. Using squares, rectangles, rhombi, trapezoids, and hexagons, students will discover how shapes are different from one another and how mathematicians identify and name them. Interactive activities and games will teach students about geometrical symmetries and how to construct polygons with many sides, including the tetracontakaihexagon! Materials needed: a printout to be provided and scissors (to cut out shapes prior to session).
Discovering Polyominoes (grades K through 3): You’ve heard of dominoes, but have you ever heard of trominoes, tetrominoes, or pentominoes? Discover the many surprising shapes you can create simply by combining single-size squares. Explore various types of symmetry using these unique objects. Warning: Solving polyomino puzzles may provide hours of fun! Materials needed: a printout to be provided, pencil, marker, and scissors. Optional materials: tape.
Tangram Teasers (grades K through 3): Exercise your mind and stretch your spatial reasoning while searching for solutions to fun tangram puzzles. Learn to create specific figures by combining seven polygons. If you get stuck, try another way! Discover multiple strategies to solve these classic dissection puzzles. Materials needed: scissors and printout to be provided. Optional materials: tangram puzzle set.
Prime Time (grades 1 through 3): Prime numbers are the building blocks of arithmetic, and they show up in all sorts of surprising places. From strange clocks to many-pointed stars, primes can teach us about number relationships and patterns. Explore primes while using skip counting to create geometric patterns and learn the origin of these very special numbers! Materials needed: paper, pencil, and printouts to be provided. Optional materials: markers.
Ghostly Graphs (grades 1 through 4): Learn the basics of graph theory by counting the ways a small ghost can pass through the walls of a given house. Discover which is more important: the number of walls, the number of rooms, or the overall layout. Explore these questions, as well as starting and ending positions, different types of paths, and other intriguing questions. Have fun in a unique and accessible introduction to this sophisticated branch of mathematics! Materials needed: pencil, paper, and markers (4 colors).
Magic Squares (grades 2 through 4): Magic squares are a set of puzzles that have long fascinated many of the world’s most brilliant thinkers. Dating back over 4000 years to ancient China, magic squares are those on which the sums of each column, row, and diagonal are always “magically” the same number! Discover surprising strategies to solve these mysterious puzzles and learn how to create your very own magic square. Materials needed: pencil and paper.
Perplexing Partitions (grades 2 through 4): How do you regroup the numbers on a grid and still keep the sums the same? Through clever counting and rearranging, discover how to build the same number with fewer and fewer units and learn to solve a unique family of addition puzzles. Materials needed: pencil, graph paper (printout to be provided).
Cryptarithmetic (grades 2 through 5): Arithmetic is fun, but arithmetic with letters is even better! Using process of elimination and clever logic, students will explore fundamental properties of base-10 arithmetic in a unique and challenging way. Join us for CRYPT4R1THM3T1C! Materials needed: pencil and paper.
Points and Shapes (grades 2 through 5): Is there an easy way to find the areas of geometric shapes? The answer lies in the geoboard, a square grid used to explore polygons. Starting with rectangles and triangles and quickly advancing to polygons of any size and shape, explore this fun and unconventional way to calculate area. Come discover the curious relationship between interiors and boundaries in shapes you design yourself! Materials needed: pencil and graph paper.
Exhibit Explorations (grades 2 through 6): The interactive exhibits at the National Museum of Mathematics offer visitors a wonderfully accessible introduction to sophisticated math topics not often covered in school. In this series, students will be able to experience an exhibit virtually, as well as participate in a hands-on activity designed to illustrate the principles behind the exhibit. Each session features a specific exhibit and includes an exhibit video, discussion, and activity. Come take a look at actual MoMath exhibits such as Math Square, Pythagorean Puzzlers, Hyper Hyperboloid, and more! Materials needed are typically school supplies, such as paper, pencil, markers, ruler, or scissors, and will be listed in the confirmation email.
Color Grids (grades 3 through 6): In this workshop, students create cool color patterns using simple rules. Each pattern is created by following a recipe, and you will try different recipes to discover new patterns. Explore simple cellular automata by generating your own infinite patterns! Materials needed: Colored pencils/markers (2 colors), graph paper, and a printout to be provided.
Hailstone Numbers (grades 3 through 6): Hailstone numbers are fascinating patterns of numbers that increase and decrease sporadically according to a set rule until they finally plummet in size and eventually become the number 1! These number sequences are easy to create but often impossible to fully understand. Come learn what these numbers actually are, why they are so mystifying, and how they might just represent the next big breakthrough in mathematics. Materials needed: pencil and paper.
Math in the Corner Pocket (grades 3 through 6): Explore angles and the law of reflection while tracing the path of a billiard ball as it bounces off the walls of a pool table. Use patterns to discover a simple method to predict in which pocket the ball will land and learn how to prove your prediction is correct. Game on! Materials needed: pencil, ruler, graph paper (printout to be provided).
Making Math Solid (grades 4 through 8): Explore geometry and discover the beautiful structure of polyhedra! Using modular origami techniques that involve folding multiple sheets of paper, students will create their very own polyhedra (e.g., a tetrahedron, a hexahedron, or a decahedron). Different days will focus on different polyhedra, highlighting their fascinating properties. Materials needed: 6 to 10 sheets of origami paper or 6 to 10 paper squares (6 inches by 6 inches).
Poltergeist Paths (grades 4 through 8): Dig into graph theory by exploring the connection between vertices and edges and the walls of a haunted house. Discover a method to find out whether a ghost can haunt a castle and whether you can draw a figure without lifting the pen. Explore how these two problems are related and what they have to do with bridges in 18th-century Prussia! Have fun in a unique and accessible introduction to this sophisticated branch of mathematics. Materials needed: pencil, paper, and markers (4 colors).

Come learn about these famous fractals and what makes them so unusual. Materials needed: pencil, paper, and printout to be provided.
Topological Tic-Tac-Toe (grades 7 through 12)
The familiar game of tic-tac-toe becomes fun and challenging when we play it on alternative topological surfaces. The typical 3×3 game board is enhanced by gluing together pairs of opposite edges together in various ways, making for more interesting games and mind-bending playing spaces. Students will learn to appreciate the ins and outs of these new objects as they develop strategies to master the mathematically enhanced games. Materials needed: sheet of paper and pencil.
