Secret messages and code-breaking were crucial to the eventual end of World War II. In England, lots of people worked at a place called Bletchley Park trying to crack messages sent in code by Germany and its allies.
Now we'd like you to do some code-breaking of your own! You can either research Bletchley Park, the Enigma machine and codes used in World War II, or have a go at making up your own code using the Caesar Wheel below.
Don't forget to post what you come up with to Class Dojo!
