Can you decipher what we wrote?

You will need a CODE CIRLE… and you’ll have to know that we used code X .

4How can you code and decode a message?

Make yourself a CODE CIRCLE.

The little circle shows the code alphabet, and the big circle shows the ordinary alphabet.

Attach the two circles together with a paper fastener so that the big one starts from the letter A, and the little one starts from the letter  X. That way your code can be referred to as code X.

Your circles must be attached together everytime so you can read any coded message with code X.

When you want to encode the letter B (in code X), look up the letter in the big circle and write down the letter directly below it. In this case this is the letter U.

I hope we have explained it well 🙂
