Computer Science

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

Selection challenge

Using selection when developing programs

Arithmetic operators

Relational operators

Logical operators

Nested selection

Good programming practices

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.

to check if the program meets the requirements and works as expected

Why is it important to test a program after writing it?

What will the following logical expression evaluate to? `(5+3/2) < 5 and 9+2 == 12`

What will the following logical expression evaluate to? `7 == 8-2 or 9 > 6`

What will the logical expression `num == (8*3)/2` evaluate to if num = 12?

What will the logical expression `age > (80/2)` evaluate to if age = 40?
