My mother babysits a boy who is currently in first grade. He is like a second son to her, and I'm asking this on her behalf. He is reading level 12 or 13 books, although not very fluently (person reading with him has to help about every 3rd or 4th word). I'm not sure he should actually be taking home books at this level. He seems to have trouble with longer words, contractions, and when sounding out words, he usually only knows one way a letter can sound. (For instance, when sounding out a word with the letter "o", he thinks it always says "ooo" instead of "ow" or the "o" sound; shoot instead of show or owl.) I've read with him and noticed this. He has ADHD, and his teacher has started testing for a learning disability. My mom wants to help tutor him this summer when he stays at her house about 1 day a week. What can she do to work with him? My experience is primarily in pre-k, I know how to teach letters and letter sounds; not words. What are some helpful books or websites or strategies you can tell me about?
