Senior Sessions: “Chessboards and Dominoes”
Monday, August 15, 3:00 pm ET (New York)
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 and dominoes.

Senior Sessions: “Math in Art: Tessellations I”
Thursday, August 25, 3:00 pm ET (New York)
Discover the wonderful world of tessellations!  Explore how geometric shapes can completely cover a plane with no gaps or overlaps and discover where tessellations appear: in nature, in ancient Roman mosaics, in Islamic art and architecture, in quilting patterns, and in the works of modern artists such as M.C. Escher.  Join us to build your own tessellations with regular polygons in this first offering in the Math in Art series.  Materials needed: pencil, paper, scissors, printout to be provided, and pattern blocks set (optional).

Senior Sessions: “Magic Squares”
Tuesday, August 30, 3:00 pm ET (New York)
Magic squares are a set of puzzles that have long fascinated many of the world’s most brilliant thinkers.  Dating back more than 4,000 years to ancient China, magic squares are those in 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.

Senior Sessions: “Math in the Corner Pocket”
Friday, September 9, 2:00 pm ET (New York)
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).

Senior Sessions: “Gallery of Graphs”
Monday, September 12, 2:00 pm ET (New York)
Dig into graph theory by exploring the connection between vertices and edges — and the walls of any house.  Discover a method to determine whether 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 learn what they have to do with bridges in 18th-century Prussia, all while enjoying a unique and accessible introduction to this sophisticated branch of mathematics.  Materials needed: pencil, paper, and colored pens or markers (4 colors).

Senior Sessions: “Polyomino Puzzlers”
Tuesday, September 27, 2:00 pm ET (New York)
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 and explore various types of symmetry using these unique objects.  Materials needed: printout to be provided, pencil, and colored pen (or marker).  Optional materials: scissors and tape.
