Senior Sessions

Once a week
2:00 pm to 2:45 pm ET

(online)

Senior citizens, exercise your brain in 45-minute math sessions!  Join MoMath’s experienced presenters for intriguing classes on a variety of stimulating topics, including topology, puzzles, and cryptography.  Enjoy the discovery and challenges in these engaging, interactive activities with a collegial cohort of mature minds.  For senior citizens / mature adults.  Online registration closes 15 minutes before each session begins.

Please note that sessions of the same name are repeated sessions.

“Grids of Life”

Wednesday, May 8
Join us to play the Game of Life, invented by John Conway and popularized by Martin Gardner.  Widely known in the 1970s (particularly among the computing community), the Game of Life is an example of a cellular automaton (CA).  Learn the rules, follow recipes, and use CA principles to generate surprising patterns.  Explore simple cellular automata by creating your own infinite patterns!  Materials needed: colored pencils or pens (two colors) and printouts to be provided.

“Skipping Towards Infinity”

Thursday, May 16

Is it possible to add infinitely many things and end up with a single finite number?  Sometimes, but the arithmetic of infinity obeys its own strange rules.  Achilles and the Tortoise never quite mastered them!  Explore this classic paradox and other surprising results that arise when considering the mathematics of infinity.  Materials needed: pencil, paper (at least 3 sheets of 8.5 x 11 paper), and calculator (optional).

“Tangram Teasers”

Tuesday, May 21
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.

“Topological Tic-Tac-Toe”

Wednesday, May 29
The familiar game of tic-tac-toe becomes fun and challenging when played 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.  Participants learn to appreciate the ins and outs of these new objects as they develop strategies to master the mathematically enhanced games.  Materials needed: pencil and paper.

“Luck, Magic, or Math?”

Thursday, June 6
At first glance, the occurrence of an “unlikely” event might seem like luck… or magic.  However, when this event occurs over and over, we have to look more closely.  With a bit of math, we will see that some events, which might seem unlikely at first, have a higher probability than intuition would suggest.  Learn how a clever magician can “read the minds” of an unsuspecting audience using a little knowledge of probability!  Materials needed: pencil, paper, colored pens or markers (3 different colors), deck of playing cards, a single die, and printout of poems (to be provided).

Math in Art III: Friezes”

Tuesday, June 11
Continuing in our Math in Art series is an introduction to mathematical symmetry and the seven patterns of friezes.  Known for their decorative purposes and often enriched with carvings, these architectural elements have been known and used since antiquity.  Materials needed: pencil, paper, colored pencils or markers (optional), and printouts to be provided.

“Chessboards and Dominoes”

Wednesday, June 19
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.  Materials needed: pencil and graph paper (printout available). Optional materials: chessboard, dominoes

“Math in the Corner Pocket”

Thursday, June 27
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 that your prediction is correct.  Game on!  Materials needed: pencil, ruler, and graph paper (printout available).
