This is the answer key for the guess the number quiz.

1. What is on button pressed?

Answers may vary. Generally, on button pressed run code when an input button is pressed. The micro:bit has two input buttons: A and B.

2. Consider the following directions

Write the line of code that creates a condition when the BBC micro:bit button A is pressed.

input.onButtonPressed(Button.A, () => {    
})

3. Write the line of code that creates a local variable and a random number.

let randomNumber = Math.random(10)

4.

If the rectangle below represents the BBC micro:bit, shade the areas that will be displayed. Explain why that particular area is shaded.

randomNumber = Math.random(10)

The random number generator will return a number from 0 to the limit. However, not including the limit unless the limit is 0. So you can place an X to represent any single digit number.
