Momsdream, I sent you a PM. I can offer a lot of help & suggestions. Your daughter's combination of being a math whiz & difficulty reading is similar to my son -- it's fairly common, but it is also an indication of a particular pattern of dyslexia. Usually kids like this are strong visual-spatial learners, and are often highly gifted, so they tend to need to learn to read with methods geared to their learning styles.
Phonetic decoding tends to elude them, because they are global, big-picture learners -- they need to have all of the pieces of the puzzle in mind for thing to make sense to them, and often have difficulty with any sort of tasks involving sequencing or step-by-step learning.
