What is reading fluency? Reading fluency is the ability to read with sufficient ease and accuracy that one can focus attention on the meaning and message of the text. Reading for understanding is disrupted by anything that impedes the mapping of print to language.
According to Parish. (2014), fluency is the ability to know how a number can be composed, decomposed, and then. using the information to use numbers flexibly and efficiently. One way to increase student number sense is through number talks (Boaler, 2013, p.5). Number talks consist of putting a math problem on the board, having students solve it, and then. having them explain their strategy for solving the problem.
