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.

This unit builds on pupils’ prior Python experience from KS3 and the Programming: Sequence unit. Pupils are ready to move beyond sequential code and explore how programs make decisions. Using flowcharts, they’ll learn how conditions control program flow and how logical expressions are evaluated. Through practical programming tasks, pupils will apply selection to create responsive, purposeful code—strengthening their problem-solving and computational thinking skills to build towards solving more complex problems.
