It seems we do, at least according to the results of a new study. The research indicates that math ability in preschool children is strongly linked to their inborn and primitive "number sense," called an "Approximate Number System" or ANS. We accept that some people are born with a talent for music or art or athletics.

Read More »During the number sense task, researchers asked the children to view flashing groups of blue and yellow dots on a computer screen and to estimate which color group of dots was more numerous. Counting wasn't an option, both because the dots were flashed so quickly and because most of the children were not yet skilled counters. The preschoolers would then verbally tell the tester whether the yellow or blue dots were more numerous, and the tester would press the appropriate button. Some comparisons were easy (like comparing five yellow versus 10 blue dots). Others were much harder (like comparing five yellow versus six blue dots). Children were informed of right or wrong answers via a high- or low-pitched beep. (You can take a test similar to the one administered to the children online here: http://www.panamath.org/testyourself.php ) The children also were given a standardized test of early mathematics ability that measures numbering skills (verbally counting items on a page), number-comparison (determining which of two spoken number words is greater or lesser), numeral literacy (reading Arabic numbers), mastery of number facts (such as addition or multiplication), calculation skills (solving written addition and subtraction problems) and number concepts (such as answering how many sets of 10 are in 100.) This standardized test is often given to children between the ages of 3 and 8 years. Lastly, the parents and guardians of the children were given an assessment that asked them to indicate each word on a list that their children had been heard to say. According to Libertus, this verbal test was administered because language and math abilities are to some extent linked through general intelligence, and the researchers wanted to make sure that the differences in math ability that they found were not just due to some children performing better on all kinds of tasks, or to some children feeling more comfortable being tested than others. Libertus and her colleagues Lisa Feigenson and Justin Halberda, faculty members in the Department of Psychological and Brain Sciences, found that the precision of children's estimations correlated with their math skill. That is, the children who could make the finest-grained estimations in the dot comparison task (for example, judging that eight yellow dots were more than seven blue dots) also knew the most about Arabic numerals and arithmetic.

Read More »According to the researchers, this means that inborn numerical estimation abilities are linked to achievement (or lack thereof) in school mathematics. "Previous studies testing older children left open the possibility that differences in instructional experience is what caused the difference in their number sense; in other words, that some children tested in middle or high school looked like they had better number sense simply because they had had better math instruction," Libertus said. "Unlike those studies, this one shows that the link between 'number sense' and math ability is already present before the beginning of formal math instruction."
