You have given me hope, Laurie. I have a 13 year old son who is dyslexic. I sure hope he improves. Dh overcame his reading struggles, but his terrible handwriting and math computation skills linger on! :D
Ds recently took the WISC IV and it showed low scores in working memory and processing speed, which sure doesn't help matters (no signs of add). Laurie, if you have any wisdom, please pass it on. Right now, ds is doing Earobics, listening to audiobooks and is starting with a Barton tutor next week. His fluency and comprehension is lousy; I will implement Lindamood-Bell's Visualizing/Verbalizing, myself, in the fall, after he gets some Barton under his belt. He'll also use Read Naturally.
To the OP, I sure wish I had started this process years ago. I knew something was not right. DS had speech problems and couldn't recognize his letters until he was almost 7. Sure signs indeed. The book that Laurie recommends is wonderful. Read and read some more. Even if it's not dyslexia, maybe you're in tune with some other issue.
Phono Graphix is probably a perfect place to start. For under $20, you can really start to be in charge of what needs to be done. I got a tutor for a few months. It helped, but just wasn't eplicit enough for my older son.
Good luck to you. Just the fact that you are in tune with your son's abilities and needs means he'll be just fine, in the end!
