+
+Guess the number with math random. 
+
+### ~avatar avatar
+
+Welcome! This tutorial will help you create a guess the number game! Let's get started!
+
+### ~
+
+Add an event handler when button `A` is pressed.
+
+
+```blocks
+input.onButtonPressed(Button.A, () => {
+})
+
+```
+
+Create a local variable of type number `x` and set it to a random number using `pick random`. `pick random` 9 generates a random number between `0` and `9`.
+
+```blocks
+input.onButtonPressed(Button.A, () => {
+    let x = Math.random(10)
+})
+
+```
+
+Show the random number on the screen.
+
+
+```blocks
+input.onButtonPressed(Button.A, () => {
+    let x = Math.random(10)
+    basic.showNumber(x)
+})
+
+```

+# guess the number challenges
+
+Coding challenges for the guess the number tutorial. 
+
+## Before we get started
+
+Complete the following [guided tutorial](/lessons/guess-the-number/activity), and your code should look like this:
+
+```blocks
+input.onButtonPressed(Button.A, () => {
+    let x = Math.random(9)
+    basic.showNumber(x)
+})
+```
+
+### Challenge 1
+
+When button `B` is pressed, we want to clear the screen. This will make it so users can play your game over and over again! Add an event handler to handle this case.
+
+```blocks
+input.onButtonPressed(Button.A, () => {
+    let x = Math.random(9)
+    basic.showNumber(x)
+})
+input.onButtonPressed(Button.B, () => {
+    basic.clearScreen()
+})
+```
+
+### Challenge 2
+
+Show an animation when you clear the screen! Choose what animation makes most sense to you. Be creative!

+# guess the number quiz answers
+
+Learn how to generate a random number on the micro:bit.
+
+This is the answer key for the [guess the number quiz](/lessons/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.
+
+
+```blocks
+input.onButtonPressed(Button.A, () => {    
+})
+```
+
+## 3. Write the line of code that creates a **local variable** and a **random number**.
+
+
+
+
+```blocks
+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.
+
+```blocks
+let randomNumber = Math.random(10)
+```
+
+
+![](/static/mb/lessons/guess-the-number-0.png)
+
+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.

+Learn how to generate a random number on the micro:bit.
+
+## Name
+
+## Directions
+
+Use this activity document to guide your work in the [guess the number tutorial](/lessons/guess-the-number/activity).
+
+Answer the questions while completing the tutorial. Pay attention to the dialogues!
+
+## 1. Describe what "input -> on button pressed" does?
+
+<br />
+
+## 2. Write the line of code that creates a condition for on button A pressed.
+
+<br />
+
+## 3. Write the line of code that creates a `local variable` called `randomNumber` and will return a number from 0 to a limit of 10.
+
+<br />
+
+## 4. Draw the area that could be lit based on the code below. Explain why you chose to draw that number.
+
+```blocks
+let randomNumber = Math.random(10)
+basic.showNumber(randomNumber, 150)
+```

+
+### Rebuild the game!
+
+The blocks have been shuffled! Put them back together so that...
+* when the user presses button ``A``,
+  * generate a random number
+  * show the number on screen
+
+
+```shuffle
+input.onButtonPressed(Button.A, () => {
+    let x = Math.random(10)
+    basic.showNumber(x)
+})
+```
