Good math students use rote memory

Students who excel at math use rote memory to solve simple arithmetic problems, while weak students calculate, concludes a new study, Why Mental Arithmetic Counts, published in the Journal of Neuroscience.

Researchers scanned students’ brains while they were solving problems.

Higher-level mathematical skills are built on “arithmetic fluency, the speed and efficiency with which correct solutions to numerical computations are generated,” researchers wrote.

This “buttresses the Common Core’s call for ‘automaticity‘ of math facts in the early grades, writes Education Gadfly.
