Talent Show
Let the girls show off their talent and plan a talent show for the slumber party. Let the girls know about the talent show ahead of time so that they can bring music to dance or sing to, or bring props for their performances. After all the girls have performed, have two or three judges decide which act is the best. Crown the winner or give her a prize.
Scavenger Hunt
Plan a scavenger hunt for teen girls to play at a slumber party. Prior to the party, make a list of the girls' favorite items, such as makeup, Miley Cyrus CDs or photos of their favorite teen heart-throbs. Hide the items inside and outside your home. Make the list as easy or difficult as you want, and award the scavenger hunt winner a prize.
Newspaper Fashion Show
Teen girls will have a lot of fun playing newspaper fashion show at a slumber party. Have the girls look through magazines such as "Marie Claire," "Vogue" and "In Style" for fashion ideas, then create their designs from newspaper. After all the girls have walked the runway in their newspaper outfits, have them vote on the best outfit and reward the winner with a prize.
