Secret Agent!

Imagine that you live the exciting life of an international spy. You need to get messages to your partners, while keeping this information safe from your enemies. How can you do this? Easy - invent a secret code that only you and your partner can understand! Some codes, like the Morse Code, aren't really secret, but have been used to send information for a long time. Other codes, like sign language, stand in for spoken language. This month, you'll learn about many different types of codes, and develop one of your own!
