ZOOM for Aspiring Secret Agents: Encrypting & Deciphering Secret Codes – 12/10 – 5PM ET – FREE

Arya Ökten and Giray Ökten will introduce aspiring secret agents to the fun in mathematical conundrums. Secret agents will learn how to create and decipher secret codes using the tools created by Julius Caesar. You will learn:

  • Where it all began and why
  • How secret codes work
  • How to both encrypt and decipher codes

This father/daughter duo is committed to making advanced mathematical concepts fun, engaging, and educational. Operations? Prime Numbers? Secret Codes? Arya and Giray have co-taught these math concepts to kids with energy and humor. Now they have a new book, complete with lots of fun illustrations, The Mathematical Investigations of Arya and Dr. O.

So… Join Arya and Dr. O to learn how to create and decipher secret codes:

  • Do you want to protect secret information?
  • Need to pass an encrypted message to a fellow secret agent?
  • Just send private messages to your friends?

Put on your best secret agent outfit, grab your spy kit, and get ready for a fun time! You will receive your own decoding tool to use in the session when you register.

FREE ZOOM to the Land of Wrong Answers and Fun – 12/16 – 5:00 PM ET – FREE

Why do we have rainbows? How do airplanes stay up? Where do tadpoles come from? Amusing and comforting answers are givenby big brother to his little sister. Authors Penny Noyce and Diego Chavez will introduce you to this pair of siblings as they meander through their afternoon and evening all the way to bedtime.

Penny, a physician, author, and supporter of science education will read excerpts from their book and reveal how this duo picked the amusing and comforting questions and answers. Diego, a native of Brazil and an artist and cartoonist who teaches art in Massachusetts, will show you how he creates the warm and funny illustrations throughout the book.

Penny and Diego want to know your favorite questions that need wrong answers. Participants will pick their favorite wrong answers. The three lucky winners of best questions will receive a copy of the book.

Submit your questions when you register.

You can always check the section at the back of the book that can clear up any misunderstandings with “What Grownups Think.”…….but why ruin all the fun with facts?
