It appears that the Key and the Master document are the same.
Here's the key: https://studio.code.org/s/cspoptional/stage/7/puzzle/1Here's the sheet for the kids: https://docs.google.com/document/d/1luezxRb3SeHnehy32SB_keXboZktutVG4RB3JNvW2r4/edit
If I'm just looking in the wrong places (the lesson is here - https://curriculum.code.org/csp/unit4/6/optional/2/), please let me know where the real key is.
Otherwise, I'll post my own answers.
Thank you for reporting this problem. I will report it to the team for correction.
Thanks for being so speedy.
My students really like these side quests, and I do too.
Goodness! This is a great lesson. I don' t know how I missed it when I taught Encryption with Keys and Passwords. Definitely going to use this lesson. Thank you.
