I've been using 8 for two years now. My old laptop did not have a touchscreen. This one does. Worlds easier. I basically set my old one up to work like Windows 7.
If you don't like the start screen, you can download a replacement like the old Windows 7 start menu. I like start menu 8.

I have it on my laptop and my brother's so that if my dad needs to use one of the laptops, he can find everything. You can customize it to make it work the way you want it to work. To get to the windows 8 start screen, you either hit start -> switch to metro or swipe in from the right side and hit start.
It is something that you have to use continuously to get used to. I'm not surprised it's confusing your daughter as it confused me at first.
