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.

Topics Covered: Problem representation Choosing suitable data types Using Boolean variables effectively Controlling iteration, including nested for loops Algorithmic thinking skills Pack contents: Powerpoint Slides Lesson plan Python files with warm up exercises and solution

A lesson on the modulo operator (remainder) represented by “%” in Python. This operator often causes confusion so it’s worth spending a whole lesson on. It is used in many algorithms and is required knowledge for GCSE Computer Science. This pack contains a complete lesson plan and worksheet and supplementary coding exercises along with solutions. 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.

This is a collection of Python implementations of algorithms discussed in the Cambridge A and A/S Level Computer Science text book. They are also suitable for other exam boards and study at GCSE for more able students. Programs included: Using nested loops to print a rectangular pattern Printing a pyramid pattern - not using functions Printing a pyramid pattern - using functions Printing a hollow pyramid pattern - not using functions Printing a pyramid pattern - using functions These algorithms are fun and satisfying for students due the the pleasing visual output. It is a good idea to give students the chance to implement them for themselves before providing solutions. The Python code given in the teacher’s resource for this course is un-pythonic and often contains errors. The implementations provided here are written in a more pythonic style, are free from errors and provide an intuitive mapping to the pseudo-code given for the algorithms. Please note that I have translated the CIE pseudo-code construct of REPEAT…UNTIL using while True: # commands if condition: break which I consider the best conceptual equivalent. I hope you find this resource helpful.
