Hi, HoosierMommy. My son was/is very similar. I've taught my son spelling very informally. We started with Dolch sight words, since those same high-frequency words will pop up often in writing, especially early writing. This seemed to build his confidence. At one point I used phonics flash cards to teach spelling, which helped reinforce some basic rules about when to choose certain letters and letter combinations. Those particular cards are well-designed in my view, and they're very cheap.

More recently I started hunting up free grade-level spelling lists on the web and just using those. I started with some good ones that used to appear at the All About Spelling website, but unfortunately they were pulled down. I haven't bought their product, but it seems like it might be worth a look if you don't feel capable of teaching your daughter in an offhand way like I did. Check out their "resource center" for some potentially helpful ideas:

When I've taught my son, I've naturally pointed out things like when consonants are doubled, the effect of a silent "e", etc. I've also pointed out suffixes, prefixes and bases. I think the things I've done most parents would naturally think to do when focusing on teaching spelling to their children, the same way we figure out on the fly ways to teach our children to speak. That's why I think that if your aim is to help your child spell better, you don't necessarily need a product; the focus and effort will hopefully naturally tend to sweep both of you along.

Another thing that I think is helpful is to pick out the occasional illustrative spelling word during reading or even during conversations with my son, and make sure he knows it. At the end of reading a challenging passage, asking him to spell some of the words he just read seems to have possibly developed his ability to memorize spellings as he reads.

Here are some old threads on spelling:
