On the home screen(s), pinch your screen. Long press a screen and drag it to trash. The rest is self-explanatory.. I had this problem myself until yahoo answers helped lol

If you're referring to home screens, the Pantech Marauder has 5 home screens. I checked the manual and it wasn't mentioned if it's possible to delete or add additional home screens. What I would suggest is for you to use other launchers such as GO Launcher EX or Nova Launcher. Those two are more customizable. You can have only 1 home screen or more than 5 if you prefer.
