The Cryptoclub: Using Mathematics to Make and Break Secret Codes

Join the Cryptokids as they apply basic mathematics to make and break
secret codes. This book has many hands-on activities that have been
tested in both classrooms and informal settings. Classic coding methods
are discussed, such as Caesar, substitution, Vigenère, and
multiplicative ciphers as well as the modern RSA. Math topics covered
include:
- Addition and Subtraction with, negative numbers, decimals,
and percentages
- Factorization
- Modular Arithmetic
- Exponentiation
-
Prime Numbers
- Frequency Analysis.
The accompanying workbook,
The Cryptoclub Workbook: Using Mathematics to Make and Break Secret
Codes provides students with problems related to each section to help
them master the concepts introduced throughout the book
