So last week I completed my second and final week back at Stuy teaching CS. We spent Monday finishing up the mode lesson and then spent most of the week on this topic - writing a computer program to automatically decode something "encrypted" with a Caesar Cipher. The post I just linked to was from when I first taught the lesson. I've refined and reworked it considerable since then but the gist is the same.

As you might have heard, I'm back at Stuyvesant teaching. Not permanent or full time - just covering for a CS teacher who's on grand jury duty. She's out for three week but since I was at SIGCSETS for the first one, I'm only covering for two. Last week and the one upcoming. I wouldn't be covering all 5 of the teacher's classes, just 3 - periods 6, 7, and 8, the second half of Stuy's intro CS class.
