NUMB3RS - Season 1 - "Sabotage" - Breaking the Code

Activity Overview

In 'Sabotage', a series of train wrecks has the FBI puzzled. Until a note is discovered at the scene of the latest train wreck, the FBI has no leads. When they see that the note contains a code written in a series of numbers, they immediately call Charlie. Charlie is able to break the code in the letter, which helps Don and the FBI find the person who caused the train wrecks. In this activity, students will use a shift cipher to decode messages.
