Course Content

3.1 Fundamentals of algorithms
This is the first lesson of a 10-lesson unit titled Mastering Algorithms & Efficiency, aimed at GCSE students (typically 14-16 years old). The lesson introduces the fundamental concept of algorithms as sequences of steps used to complete tasks. It draws clear distinctions between designing an algorithm and implementing it in code, using relatable, real-world analogies like recipes. This lesson closely adheres to the National Curriculum for England’s Computer Science programme of study, ensuring relevant knowledge progression from key stage 3 to GCSE level.
