Secret Codes & Number Games

Cryptographic Projects & Number Games for Children Ages 5-16

Authored by Dr. Dev Gualtieri Ph.D.

Children enjoy making and sending secret messages. Secret message making, called cryptography, has become much more interesting with the advent of computers and the Internet. It's interesting to learn the basics and understand what's happening "under the hood" of cryptographic applications.

This book has a spectrum of content that's interesting to children of all ages. It gives instructions on how to encode messages in a variety of simple and complex ways. Children can create messages using traditional ciphers, some used for thousands of years. Messages can be coded through conventional techniques, such as Morse Code, semaphores, and Braille, but messages can be encoded also as music, pigs and flowers.

Advanced cryptography uses a lot of mathematics, but this book shields the younger readers from most of the math. However, a few interesting number games are included, and ways to create art from words and phrases.
