Daily Sessions
Sessions are available for grades pre-K through 12, as indicated above.
After you register for your 45-minute session, you will be sent a link and instructions so you can join the fun via Zoom, the free video conferencing platform. Multiple family members may participate in a session, but please limit the link to one device, as there is a limit on devices.
Session Themes
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 pentonimoes? 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.
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, on a magic square, 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.
Points and Shapes (grades 2 through 5): Is there an easy way to find the area 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.
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).
Möbius Madness (grades 3 through 6): Students construct fascinating topological objects such as Möbius bands, discovering their fundamental patterns and structures. Hands-on activities lead students to discover the surprising properties hidden around every twist and turn! Materials needed: 4 strips of paper (2 inches by 11 inches), scissors, tape, and markers (2 colors).
Secrets of Cryptography (grades 3 through 6): Explore cryptography, secret codes, and ciphers! Students are introduced 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! Materials needed: paper, pencil, printout to be provided, and scissors. Optional materials: brad, paper fastener, or pin.
Vote Counts: Packing and Cracking (grades 4 through 8): Get a glimpse into the mathematics of elections by becoming a “legislator” for a day. Explore how election districts are drawn and learn about “cracking,” “packing,” and the meaning of wasted votes. Have fun while analyzing the fairness of representation in an election and increasing your civic engagement and understanding through math! Materials needed: paper, pencil, markers, and printouts to be provided. Limited time only, special pre-election class.
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 if a ghost can haunt a castle or if a figure can be drawn 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).
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).
Rep-tiles (grades 5 through 8): Come discover mathematical rep-tiles, geometric shapes that can tile into repetitions of themselves. Learn about areas, scaling, and mathematical proofs, while solving fun rep-tiles puzzles! Materials needed: pencil, paper, printouts to be provided, and scissors (to cut out shapes prior to session).
Crazy Dice (grades 5 through 8): Once students find the probability of rolling a given sum with a pair of standard dice, they are challenged with finding a different way to number their dice to get the same probabilities. Crazy! Materials needed: sheet of paper and pencil.
Win like a Mathematician (grades 5 through 8): Games are not only fun to play, but fun to solve! Mathematicians have invented many games that present challenging math problems, some of which are still unsolved. Join MoMath’s education team online to learn, play, and analyze a variety of mathematical strategy games. Different days focus on different games, including classics such as Tic-Tac-Toe, Nim, and Hex, as well as a few mystery-guest games! Materials needed for the games are minimal and will be listed in the confirmation email.
Chessboards and Dominoes (grades 6 through 10): What shapes can you fit together to cover a chessboard? Dominoes? Trominoes? Learn about mathematical proofs while exploring patterns of odd and even numbers and experimenting with real dominoes and chessboards. This challenging session is for students who love math and are ready for perplexing puzzles! Materials needed: pencil, graph paper (printout to be provided). Optional materials: chessboard, dominoes.
Evening the Odds (grades 7 through 12): The probability of rolling different sums with a standard pair of dice depends upon the sum in question. This activity guides students to find ways to renumber their dice so every sum appears with the same probability. But then, what sums are possible to fit into this scheme? How many different sums can be rolled with equal likelihood? The answers to these questions and more are found in this activity. Materials needed: sheet of paper and pencil.
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 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.
Puzzle Sensations (grades 9 through 12): Explore mathematical puzzles that grabbed the headlines! Learn to solve spectacular and controversial puzzles using logic, probability, and basic graph theory. Develop puzzle-solving strategies while diving into these news-making mathematical conundrums. Materials needed: pencil and paper.
