I've found a good way to start youngsters is to show them some of the sites dealing with shooting, archery, hunting, such as Outdoor life, Shooters.com, and others. The same with the Magazines, Rifle and Handloader are two good ones, and others from all disciplines.
Let her start to save her money for the ammo she'll shoot. My spray and pray soon developed into good marksmanship when I had to buy the ammo.
A few trips into the woods or fields just to watch and scout will expose her to different areas of study, birds, animals, flowers, trees, poison ivy, the different sounds, sunups, sundowns, game habits, game sign such as tracks, food preferences, day/night activity,
nests, bedding areas, trails, ad infinitum.
Pick some brains of hunters to learn tricks of the trade--squirrel won't come out from behind the limb, throw a big rock or stick off to the side about 20 yards and the curious little devils will usually pop up to see what made the noise. Pheasants will usually go up and then level off, shoot when they level off and any lead is usually unnecessary.
Safety is not for sale or barter. A few big watermelons shot with a decent sized pistol or rifle round with good velocity and good hollowpoints seem to make a lasting impression as to what a gun can do. Kids can equate a blown watermelon to what would happen to their own heads, thus the safety issue stands out as real and not just something adults preach about.
