Week 8- 10/11

This week was special because we had a guest speaker come into our class and talk about different types of codes and ciphers. I also liked learning about codes when I was younger. My friends and I would write letters and notes to each other using codes. The two types of ciphers that we learned about were substitution ciphers  and transposition ciphers. Substitution ciphers are based on the shifting the alphabet a certain amount. Transposition ciphers are based on mixing up the letters in the message such as anagrams. Throughout the class, we wrote and decoded messages to our partners. It was a very fun class to have right before fall break.
