I have recently added the option of using the See to Spell (seetospell.com) flashcards in sight word study. They seem to really work for my right-brained students. They were designed to work in tandem with the Barton Reading and Spelling program. Each sight word is illustrated and has a sentence to accompany it that goes with the illustration. There is also a great deal of uniformity throughout the series. For example, the letter <h> usually has some type of building, the letter <o> is usually a male face, while an <a> is usually a female. Kids find them to be more fun and engaging, and they seem to work better than some of the other methods. Right not they are only available for Books 3, 4 and 5, but hopefully they will produce some for the whole series soon!
