Cool Beans: there are many ways to do the A chord in that position. Few more advanced players stick with just one. To someone new to that chord, I would start with a three finger that goes 2, 3 and 4 (fingers are usually numbered starting with the index or pointing finger as 1 and the pinky as 4. I use my thumb on some chords and that is designated by a T instead of a number). Strings are numbered from the treble to the bass as 1 through 6 with 1 being the high E and 6 being the low E two octaves below it. (None of these things are written in stone because there is a move on to reverse the string numbering process, and it would make one heckuva lot more sense, IMO. Lord knows where that will end up. BUT, for now, the above is what we have.

No post on this thread is wrong. Depending on the style of music your daughter will play, whether she's finger picking, strumming or flat picking, each of the aforementioned chordings have a place in her future reportoire of A chords. There ARE chord formations which are just plain wrong because they hinder fluid changes, but at this time and in this position, the A just ain't one of them.
