Task 7: Option 3

Exploring variables.

Variables are an important component of programming languages, as they store data that can be modified and retrieved later. The program that I wrote in Scratch uses a variable to control the rotation of the cat in a while loop. As the cat rotates, he tells us his current direction in a speech bubble.

Children in upper primary could use variables to present some information about the current state of the program on the screen (eg: the position or colour of the cat, or what the current backdrop is).
