A computer mouse is a small device that you use to control a
computer. It looks like a little box with buttons on top. The mouse has a long
tail that connects to the computer, and it helps you move a small arrow on the
screen. When you move the mouse on a table, the arrow on the computer screen
also moves. The buttons on the mouse can be clicked to select things on the
computer. It's like a special remote control for the computer!
