+
+Let's learn how to show the lucky number 7 on the LED screen.
+
+### ~
+
+To create a new script, go to the [Create Code](https://www.microbit.co.uk/create-code) page and tap `New Project` under **Block Editor**.
+
+We will use `show number` to display a number on the screen. The argument (`7`) is the number to display.
+
+```blocks
+basic.showNumber(7)
+```

+# lucky 7 blocks challenges
+
+Coding challenges for lucky 7.
+
+## Before we get started
+
+Complete the [lucky 7 activity](/microbit/lessons/lucky-7/activity) and your code will look like this:
+
+```blocks
+basic.showNumber(7)
+```
+
+### Challenge 1
+
+But we also should pause before showing another number. Let's add a pause of 500 milliseconds.
+
+```blocks
+basic.showNumber(7)
+basic.pause(500)
+```
+
+### Challenge 2
+
+### @video td/videos/lucky-7-1-2
+
+What about other multiples of 7? Let's display the next multiple of 7 on the screen!
+
+```blocks
+basic.showNumber(7)
+basic.pause(500)
+basic.showNumber(14)
+```
+
+* Run the code to see if it works as expected.
+
+### Challenge 3
+
+Keep displaying multiples of 7 such as 21 and 28, but don't forget to add pauses between the numbers!
