My DD9 has ADHD with terrible auditory processing, and at the moment, she's really being held back by her horrible spelling. Her school relies almost entirely on phonics, and she doesn't seem to hear the phonemes at all. Interestingly enough, she's great at spelling long, complicated words for which she can't even attempt to use phonics, but she mangles very basic words. I should also note that she had a huge gap between her WISC picture span (16) and digit span (7), so she is a strongly visual learner.

Are there any good visual-based rather than auditory-based spelling resources? Do any of you have advices on how to approach spelling for a child with this profile? Everything I've found seems to be phonics based, and that just isn't working at all for her.
