There are 4 codes from throughout history in which students need to break. Each code gets progressively harder leading to the final code of a simplified Enigma machine. It is impossible to solve a code if the previous one has not been cracked as each one provides vital clues for the next code. The final code (the simplifed enigma) once broken is a 3 digit number.

This resource can be used in many different way. One way is buying a 3 digit combination lock and locking a box/locker full of prizes. Then send all students the presentation. Or send all students one code a week if you want to stretch it out more.

The first slide needs to be edited to suit your plans.
