Description

In this unit pupils will be introduced to structured programming. They will explore the differences between functions and procedures and use functions to return values in programs. They will be introduced to the concept of scope and how parameters can be used to reduce the need for global variables.

This unit introduces pupils to the structured approach to programming. They will determine why subroutines are used in programs and how they are used for decomposition. Pupils will have already used built-in functions in their programs but they will now write their own. They will learn how to structure a function and will revisit trace tables in order to trace the input, process and output for various functions.
