- Use a
Vigenere Tableau provided in the station or this interactive Vigenere tableau to complete
as many of the self-checking cards as you need to for practice. When you understand the cipher and believe
you can correctly use it, you may move on to the Crypto-Practice sheet. You and your partner can work together to
solve the riddles on the front of the cards and then check your solution with
the correct answer located on the back of the card. If you do not get the right answer, see if
you can figure out your mistake. If you
need to, ask for help! Mrs. Tuttle is
nearby to help!
- Use a Vigenere Tableau or this interactive Vigenere tableau to complete the Crypto-Practice Sheet in the station. The crypto-practice sheet will offer you a clue to the location of an object hidden in the room. Once you have deciphered the clue, write the plaintext for your guess about where the object is hidden. Then you will use your cipher disk to encipher your guess.
- Complete the Frayer Method sheet in the station by explaining the vocabulary word on it with your partner.
- In your crypto-journal, write 2 positive aspects and 2 negative aspects of the Vigenere Cipher.
- Put your Crypto-practice form and your Frayer method sheet in the completed papers folder and move to the next station on your station card.
