Description

In this unit pupils will explore the benefits of good programing practices and why subroutines are used in programs. They will create conditions in programs which use arithmetic, relational and logical expressions. They will develop their understanding of selection and explore nested selection.

Having already strengthened their understanding of sequences, pupils are now ready to explore how programs make decisions. Selection is introduced at this stage to help pupils move beyond linear code and begin writing programs that can adapt to different situations. Understanding how conditions control program flow and how logical expressions are evaluated develops their problem-solving and computational thinking. This ensures pupils can design more purposeful and responsive programs, laying the groundwork for tackling increasingly complex challenges in computer science.
