one idea may be to use a cardboard strip half the size of a ruler and cut out a small window big enough for a word to fit in it. as she slides it along the sentence, she will notice the white spaces between words easier...hopefully. another idea is to ask her the beginning and ending sounds as she looks at the one word she is reading...maybe with three or four word sentences. i don't know if this will help her but just some ideas that have worked for me.
