I have two dyslexic children. We didn't realize the older one was dyslexic until high school, but for my youngest I was much more aware and began working with her sooner. Neither has been formally diagnosed.
1 - Reading Reflex
I have a friend who is a reading specialist trained in Orton-Gillingham and she recommended Reading Reflex which was so valuable for us. My daughter was about 9 when we first used Reading Reflex. This is a really affordable and practical solution for moms wondering what to do.
2 - Dyslexia Tool Kit
After we spent a couple years on Reading Reflex, I searched for another practical help for her to focus on reading fluency and I found The Dyslexia Tool Kit which contains 24 tools that can be implemented separately or in conjunction with others. We didn't use all of the techniques, but the ones we chose really helped her greatly.
3 - Short Cuts to Long Words
She is now 14 and last year (8th grade), I wanted to focus on being able to decode long words. I found this resource - Short Cuts to Long Words by Nancy Lewkowicz - and ordered it sight-unseen. It has really helpful. The website gives an overview of the method. Looking back at the website now, I see there is a higher level of this method that I may order for her this year. http://www.thewordworkshop.com/workbks.html
4 - Colored Overlays
Another tip that really helped my oldest son was colored overlays. He found that using a blue overlay on a white page really helped him to read better. Other dyslexics find success with different colors. I first heard of this when I was teaching school. Irlen is the company that did the initial work with colored overlays, but they are expensive. At first I used colored overhead transparencies, but later I found a company at a homeschool conference that was selling colored overlay rulers. (I can't remember which company since it's been a few years now.) These are similar, although ours are in varying widths.
