Division: A- Elementary School
NC Essential Standards Alignment: Science as Inquiry
Event Rules: Codebusters A Rules 2021
Event Score Sheet: None
Teams will cryptanalyze (decode) encrypted messages using cryptanalysis techniques and show skill with ciphers by decrypting a message.
Teams must bring a writing utensil. No other resources are allowed.
High score wins
- Students do not have to work through each cipher together – divide and conquer the test! You are allowed to take it apart.
Will the students be given the Caesar offset number or will they have to figure it out?
– If we give the Caesar offset, it will be worth less than if we don’t, but they might see it both ways!
What is the best way to study for this test?
- make test in the Codebusters tool – this is how all the tests will be made this year, so students should get used to the format. They can make ciphers for each other too – you can’t break it, let them take a sentence and change the cipher type to see how it changes what will print on the page!
