Yipee, classes are finally under way! It was wonderful meeting students who I'd not worked with before and to reconnect with those I already know. The goals of the first week of classes were to get to know each other, and to start encrypting and decrypting messages. We also talked about this year's theme; Top Secret Communication! We will be looking at communication in general, as well as investigating codes and ciphers. We will also be creating our own virtual radio station. Students in all the classes had some great ideas for the virtual radio station; I'm really looking forward to that coming together later on in the year.
For the first part of the year we will be spending time learning about different ciphers and codes. In week 1 we learned about the Caesar shift cipher (try saying that 10 times fast!) Students encrypted and decrypted messages using this cipher. Here's another message to decrypt (it has a Caesar shift of 3--use the alphabet strip below to help you solve it):

That's all for now, thanks for checking in.
