Getting your head around while loop - ITERATION for beginners.

Understanding variables and loops are the most significant aspects of coding. It is important for students in early stages to grasp the concept of how loops work if the are to be successful candidates for computer science. This power point presentation is a scaffold building fundamental steps required in understanding and applying loops using python. Students must already know how to use basic input and output functions in python. The language and terminology used is simple enough for a non specialist to use and teach a coder at beginner level. The python idle software is available to download for free at https://www.python.org/downloads/. After students have fully grasp the concept of loops and how they work, they extension task will provide a challenge for them to apply their knowledge, using computational thinking to improve their code.
