I've got a list of tutorials I found online - I'm sure there are some in there that you would like to have her make.
I would let her pick it out to be honest with you. Kids are picky. Just sit her down, have her go through the tutorials and if she sees something she likes that is above her, explain why and say, let's bookmark this for your next project... and then move one to the next one.
There are just so many possibilities out there and without knowing what SHE wants it to look like, it's hard to know what to suggest.
Here's a link to my purses page - also suggest to her a tote bag as well. That might be even easier.

There is a tote bag tutorial listed on there for a 6 pocket tote - it is really easy and impressive when you are done. I bet she would like that - and you can point out that they would make great teacher gifts too - this way you kill a few birds with that pattern stone - have her make hers first, then she can make another for her teacher and she'll get more practice!
