Unit Summary
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.
Lesson Summary
You will learn to define a variable as something that is changeable.
Key Notes
- Data can be stored as a variable.
- The way a variable changes is defined by the programmer.
- Variables can be used to store numbers or letters.
Vocabulary To Learn
- change: to update the value of something in a program
- variable: a named piece of data stored in a computer's memory which can be accessed and changed by a computer program
- name: the label given to a variable so that the programmer knows what it is for
- value: the numbers or text stored in a programming variable which can be used or changed
Common Mistakes To Avoid
- Variables are only for numbers.
3 Quick Questions (With Answers)
1. Describe the system or process from this lesson in clear steps.
Data can be stored as a variable. The way a variable changes is defined by the programmer.
2. Define this computing term and give one practical example. 'change'
