GCSE Computer Science Caesar Cipher Practice Worksheets

Practice encryption and decryption for GCSE Computer Science - e.g. Edexcel 3.4.2: understand how a Caesar cipher algorithm works.

It makes sense to give students lots of practical experience with an algorithm before trying to implement it in code. These worksheets give students an opportunity to encrypt and decrypt messages using the Caesar cipher - an activity which most find intrinsically fascinating.

We are committed to providing the highest quality teaching resources which will inspire and engage students while giving teachers everything they need to deliver first-class lessons.
