Samantha on the other hand, she has been diagnosed with Dyslexia/Dysgraphia/Written Expression Disorder. These rulers were designed perfectly for her!! She prefers the pink one, but there are random ones stuck in random books of hers. She uses them almost ALL the time. Samantha has told me several times that they help her with the reading, especially when she is reading something that is a paragraph, as opposed to individual sentences. These rulers have been somewhat of a blessing and I can see that we will continue to use them in the future.
