This unit explores the concept of variables in programming through the development of games. Pupils will investigate what variables are and relate them to real-world examples of values that can be set and changed. Then they use variables to create a simulation of a scoreboard.

Using variables in programming to develop a game

a placeholder in memory for a single value

What is a variable in a computer program?

What does the value of a variable represent?

Put these steps in order for using a variable in a program:

What happens to a variable’s name when the program runs and the data changes?

changing your name from “Tom” to “Sam”

Match each example to the correct keyword:

What is the data stored inside a variable called?

Put these actions in order for changing a variable’s value during a game:

What do we call the label given to a variable?
