New research shows that there is a link between an in-built 'number sense' and maths ability.


If you struggle with figures, you were probably born that way, research has suggested.


Being good at mathematics may be entirely pre-destined – you either have it or you don’t.


And those who find the numbers never add up shouldn’t feel too dim – mathematical talent does not appear to be linked to all-round intelligence.

Previous research has indicated that ‘number sense’ is basic to humans.


We use it to estimate such things as the number of seats in a cinema or crowd sizes.


U.S. psychologists at Johns Hopkins University in Baltimore made their finding after testing children too young to have been taught mathematics.


During the study, 200 four-year-olds viewed flashing groups of blue and yellow dots on a computer screen and were asked which colour was shown the most.


The children then had to count items on a page, determine which of two numbers was greater or lesser, as well as read numbers.


They were also tested on calculation skills, such as multiplication. The participants’ parents were then asked about their child’s vocabulary.


'Unlike previous studies, this one shows that the link between "number sense" and math ability is already present before the beginning of formal math instruction' Dr Melissa Libertus, John Hopkins University


The verbal test was done because language and maths abilities
are thought to be linked through general intelligence.


The researchers wanted to be sure success in maths was not part of an ability to perform better in all sorts of tasks or to some children feeling more comfortable being tested than others.


The results, published in the journal Developmental Science, showed that children who got the best score in the dots test were also the most competent at the maths tests.


Dr Melissa Libertus, who led the study, said: ‘Previous studies testing older children left open the possibility that maths lessons determined number sense.


‘In other words, some children looked like they had better number sense simply because they had better maths instruction.


‘Unlike those studies, this one shows that the link between number sense and maths ability is already present before the beginning of formal maths instruction.


‘One of the most important questions is whether we can train a child’s number sense to improving his future maths ability.’
