- Complete as many of the self-checking cards as you need to for practice. When you and your partner think that you understand how to use the shift cipher, you can move on to step 3. 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! To complete this assignment, you may use one of the cipher wheels in the station or you can use the online cipher wheel. You can find the online, interactive cipher wheel by using the link below.
- Use one of the tools mentioned in step #2 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.
