My almost 11 yr old, at the beggining of the year was a pretty good reader, but she skimmed a lot when reading to herself. She also was a horrible speller. I started having her read aloud every day and do Spelling Wisdom almost every day. At first we did spelling dictation from her copy work, then switched to SW. We also incorporated SW words into Spelling City (an online game based spelling program).
In September she could read one page aloud. Now she can read 6 or more! Her spelling has improved. We are still working on the skimming habit. 🙂
HTH!
