The Leader Manual accompanies the Student Cipher Handbook and helps teachers lead a CryptoClub program. It provides suggestions for teaching, along with an answer key, and discusses connections to middle-grade mathematics. It also describes games and activities that provide students with additional practice in an engaging, informal way.
The 3-year license provide access to the Leader Manual eBook through our online platform, Flourish, along with resources to support implementation of the activities.
