Used Bob Books with my kids. Absolutely the best phonics based reading program. The "books" are pamphlets that initially focus on one vowel pronunciation and a few consonants. They have funny plots and are so short attention span is not a problem. They gradually ramp up the complexity so it's easy for the kids to advance.
So, even if you are trapped with a teacher who insists on using "modern" methods and your kid is falling behind, a few minutes with Bob each night is the cure.
