Often when children are learning to read they sound like robots. The are looking at every letter and word so carefully that they sound staccato. They read word by word by word, which is also how they often comprehend what they are reading, in small parts rather than the whole story.
In order to help children break the 'robot reading' habit, we tell students to make reading sound like talking. Then read a sentence of two to model smooth, fluent reading. With practice they realize that it is actually easier to read fluently.
To practice fluent reading, encourage your child to reread books that he or she is familiar with. Knowing the story makes it easier to read smoothly.
