This is a PowerPoint I developed on code-breaking, going through some of the histories of code-breaking, particularly focusing on the enigma machine and WW2... 32 slides!
I normally use 20 code-breaking activities from the enigma project as a competition and the answers are included in the PowerPoint, but I have NOT attached the files!! However, if you message me after purchase with your EMAIL then I will email them to you. I do not want to publish them as they are not mine to publish, but they are free to use and can be found on the internet.
NOTE: Feel free to browse my shop for more excellent free and premium resources and as always please rate and feedback, thank you.
