What other interesting examples of codes from history or the modern-day (digital or non-digital) can you find to inspire or support a lesson about encoding and decoding messages?
Throughout history there has been several examples of codes, for example Sir Francis Bacon developed a binary code to represent the 24 letter alphabet (thank you Dr Spencer Reid).
Sir Arthur Conan Doyle also used a code in one of his Sherlock Holmes novels involving dancing men to represent different letters. This could be used as inspiration for in your own classroom.
