used when there is more than one possible path for a program to follow

an expression that evaluates to True or False

selection when there is more than one path for a program to follow

Using selection when developing programs

Arithmetic operators

Relational operators

Logical operators

Nested selection

Good programming practices

Selection challenge

Programming project: selection I

Programming project: selection II

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.

Programming: selection

a symbol or word that instructs the computer to perform a specific calculation or action

an expression that results in a numeric value

sometimes known as floor division, is when any remainder of a division is discarded

an operation that gives you the remainder when one number is divided by another

compare two values and produce the result of True or False

an expression that combines relational and logical operators

a block of code where a selection block is placed within another selection block

text within source code that is ignored by the compiler or interpreter, used to help programmers understand the code

the name that a programmer gives to a variable, constant, or subroutine

refers to the ease with which maintenance activities can be performed on code, such as correcting errors

the features, functions, and tasks that need to be completed for a project

a smaller section of a wider problem that has been decomposed to make solving the problem easier

a way of expressing an algorithm that is independent of a specific programming language

defines the main stages of software development

a document that sets out the tests that will be carried out during testing

an error where the code has been structured incorrectly and the syntax rules haven’t been followed

an error where the program will run, but won’t do what the programmer expected
