Introducing variables

Updating and changing values in a variable

Improving a game

Design a game that uses variables

Design to code

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.

Which of these is an example of improving a game?

to help you remember what each variable is for

Why should you choose clear names for variables in your project?

What is the main purpose of a design in programming?

Put these steps in order for creating a Scratch project:

to catch different mistakes at different times

Why is it important to test your code more than once?
