Of course this went well, since every kid (and most adults, I would assume) think basic cryptography is cool. We made cipher wheels and talked about the enigma machine and I got the most rapt attention I have EVER received while teaching.
After teaching simple Caesar ciphers (where you basically just shift the alphabet), I challenged the kids to write sentences and told them that I could break any of their codes (there are only 25 possibilities for Caesar ciphers - they're really easy to break - and I told them this, but the kids think I am AWESOME). Messages included:
-Yay! Spring Break is almost here!
-Ms. Twine is crazy
-First period is the best math class
-Math is my favorite subject
And then, I found an anonymous note left on my desk.

Which is, decoded: I decided to take stats.
I have no idea who wrote it, but someone in my fifth period geometry class has decided to take my AP Stats class next year. AND THEY TOLD ME IN CODE. I don’t think it gets cuter than that.
