Activity 11 Level 5 - Operators and Variables

Coding with Variables in Scratch

Create code in Scratch that mimics the throwing of a die using a random number generator, selection, a variable, and output. The instructions below will help you to write the code.

Roll the Dice - Instructions

Before you start this activity, you will need to be familiar with Scratch. It would also be helpful to know how to declare and use a variable.

Create a variable by clicking on the ‘Make a variable’ button in the ‘Variables’ code section. You can name it anything you like. In this example, it has been called ‘Die Value’

Scratch: Make a variable

After that, add a block that will start your code running (e.g. pressing the green flag), followed by a block that sets the value of your variable to a random value between 1 and 6

Scratch: On code start, pick random 1-6

Add an if...else block to your code. If the random number equals 6, the sprite should say "You can start the game!" for 2 seconds. Otherwise it should say "Too bad - try again!" for 2 seconds. Test run your code to check that it behaves as expected.

Scratch: Cat says "You can start the game!"

Add a loop to your code that will loop until the random number is a 6. You will need to test this step carefully and debug any unexpected behaviour!

Hint: adding this block at the start of your code will help!

Scratch: Hint: Set to 0
