History of Secret Messages

There are numerous lessons available to create Secret Messages. I would suggest that all ability groups would start with the simple Caesar Cipher. 



Pupils write their secret message on a piece of paper. This could be a simple message using simple Caesar cipher. This could be further developed by generating a message using a virtual Enigma Machine Emulator http://enigma.louisedade.co.uk  Lesson ideas on Secret Messages http://www.mathsisfun.com/games/secret-messages.html 

You could use Enigma machines. Perhaps you can invite the Enigma Project to your school or use virtual Enigma machines. Enigma Maths Project http://enigma.maths.org/content/
