There is no one component that is more important than the others. They work together and should be given equal time and attention. Children who can read say words quickly but not accurately will not have the proper expression nor will they understand what they have read. They are not fluent readers. Children who cannot read accurately cannot gain the speed, expression, or comprehension needed to be fluent readers. You can see that while one may lead to the other, each is equally important for children to become excellent readers.
