Is it still important to teach basic facts to students? Will using a calculator delay the acquisition of basic facts?
We definitely need to teach basic facts. The calculator with you always is the one between your ears. Mistakes on a calculator are easy to pick up if you have the knowledge of basic mathematical facts. A calculator is not a substitute for lack of mastery of basic facts; it is a supplement. A calculator only does what it is instructed to do. Students require knowledge of basic facts to estimate and to determine the reasonableness of the results. The knowledge of the facts leads to more confidence in mathematics and even in the use of the calculator. If students are encouraged to estimate results before doing a question or exercise, they will require knowledge of basic facts early. This need should assist in an earlier rather than later acquisition of basic facts.
