What is a "menu"?
You will learn what a menu is in plain words.
A menu is a list of choices you can pick from.
It opens when you tap a button. Then it shows options to choose.
Often the button is three lines or three dots in a corner.
For example, a menu may let you pick Settings, Help, or Sign Out. That is a menu.

Look in the top corners of the screen to find the menu button.
