Calculators don't subtract from learning
Elementary students who have already learned basic math skills can work through more questions and make fewer errors if they use a calculator without hurting their scores on subsequent tests, according to a recent study. "It is important children first learn how to calculate answers on their own, but after that initial phase, using calculators is a fine thing to do," said co-author Bethany Rittle-Johnson.
