Use a sight approach to reading rather than relying solely on phonics.
Silent reading is preferable to oral reading. Ask comprehension questions and allow them to find answers through reading silently at least part of the time.
Teach them to use their finger as a visual guide in reading. It keeps them from jumping from word to word around the page. (If this symptom is noted, visual tracking is suspect, which often responds to 6 months of vision therapy.)
Use a frame that shows only one line of print at a time.
VSLs respond well to poetry. Use rhyme and rhythm to enhance reading.
Offer them books - even adult-level books - in their areas of interest. Gifted VSLs can often find answers to the questions that pique their curiosity in very advanced books, even if they can only decode a fraction of the words.
Give them books with lots of pictures - even comic books.
Don't require them to read every word on a page. instead, encourage them to make a photographic imprint of each page. Ask them where on the page they can "see" a particular idea in their mind's eye.
Try using enlarged print.
Teach them word patterns, roots and affixes, and decoding as puzzle solving.
Use books rich in visual imagery (e.g., The Chronicles of Narnia, Harry Potter, etc) to enhance interest and ability in reading. (Be award that some visual-spatial learners may need initial help in learning to visualize.)
