It is a good idea to structure parties for 12-year-olds around a specific theme to match their interests, such as fashion, animals or solving mysteries. Activities are a particularly good option, such as baking, scavenger hunts or sports.
For 12-year-olds who are into fashion and dressing up, a good way to let them show off is to purchase a selection of inexpensive clothing and accessories for the participants to try on and accessorize with. Setting up a runway using paper, sheets or an existing pathway will add to the overall theme. Taking photographs and compiling these into an album makes for good mementos.
For animal lovers, a trip to a local animal shelter with treats for the rescue dogs and cats can be a rewarding and enjoyable experience. This could even be combined with a scavenger hunt beforehand, such as to gather together treats, food and other objects that could be of use to the animal shelter.
Murder mystery themes are easy to arrange and great fun to experience. There are many kits for sale that make setting up and organizing the activity quick and simple.
Whatever activity or theme is chosen, a well-planned structure will be of great help in keeping things from getting too wild.
