Basic facts need to be developed to the point that they are done automatically.  Studies have found that lack of math fact retrieval can impede participation in math class discussions, successful mathematics problem-solving, and even the development of everyday life skills. Rapid math-fact retrieval has been shown to be a strong predictor of performance on mathematics achievement tests.

Often fluency with numbers is compared to knowing basic facts; however, fluency is much more than fact recall.  Fluency is knowing how a number can be composed and decomposed and using that information to be flexible and efficient with solving problems.
