Fluency is defined as the ability to read with speed, accuracy, and proper expression. In order to understand what they read, children must be able to read fluently whether they are reading aloud or silently. When reading aloud, fluent readers read in phrases and add intonation appropriately. Their reading is smooth and has expression.
Children who do not read with fluency sound choppy and awkward. Those students may have difficulty with decoding skills or they may just need more practice with speed and smoothness in reading. Fluency is also important for motivation; children who find reading laborious tend not to want read!
Reading fluency is the ability to read a text easily. Reading fluency actually has four parts: accuracy, speed, expression and comprehension. Each part is important, but no single part is enough on its own. A fluent reader is able to coordinate all four aspects of fluency.
