Some Kids Have Poor Intuitive Grasp of Math

Some Kids Have Poor Intuitive Grasp of Math With some kids, it’s not just that math is hard and requires work to learn — there’s a poor “gut sense” of numbers that can lead to a mathematical learning disability and difficulty in achieving basic math proficiency.

Researchers write in the journal Child Development (e-publication ahead of print) that this inaccurate number sense is just one cause of math learning disabilities, says .

According to lead researcher Michele Mazzocco, Ph.D.,  of the Kennedy Krieger Institute, approximately 6 to 14 percent of school-age children have persistent difficulty with mathematics, despite adequate learning opportunities and age-appropriate achievement in other school subjects.

Unfortunately, the learning difficulties can have lifelong consequences when it comes to job success and financial decision-making.

As a result, broad initiatives to learn the nature and origins of these learning difficulties has led to studies to define mathematical learning disability (MLD), identify its underlying core deficits, and differentiate children with MLD from their mathematically successful counterparts.

The new study showed that children with a confirmed math learning disability have a markedly inaccurate number sense compared to their peers.

But Mazzocco said students without a MLD who were below average in achievement performed on the number sense tasks as well as those considered average. For them, number sense doesn’t seem to be the trouble.

“Some children have a remarkably imprecise intuitive sense of numbers, and we believe these children have math learning disability, at least in part, due to deficits in this intuitive type of number sense,” said Mazzocco. “But other students who underperform in math do so despite having an intact number sense. This demonstrates the complexity of determining precisely what influences or interferes with a child’s mathematical learning.

Mazzocco said difficulty learning math may result from a weak number sense, but it may also result from a wide range of other factors such as spatial reasoning or working memory. “While we should not assume that all children who struggle with mathematics have a poor number sense, we should consider the possibility,” she said. 

From this perspective, researchers decided to gauge number sense among a group of 71 children who were previously enrolled in a 10-year longitudinal study of math achievement. The students, all in the ninth grade, completed two basic number logic tasks.

In the number naming task, they were shown arrays of dots and asked to judge how many dots were present, without allowing enough time to actually count them.

In the number discrimination task, the children were shown arrays of blue dots and yellow dots and asked to determine whether the blue or yellow array had more dots, again, without time to count them.

The researchers then compared the performance of four groups of students, who over the 10-year study, consistently showed having either a MLD, below average, average or above average math achievement.

Students with MLD performed significantly worse than their peers on both of the number tasks. The study findings suggest that an innate ability to approximate numbers, an intact ability present in human infants and many other species, contributes to more sophisticated math abilities later in life, while a less accurate ability underlies MLD.

Additionally, the findings reveal that a poor number sense is not the only potential source of math difficulties, reinforcing that a “one size fits all” educational approach may not be the best for helping children who struggle with math.

“A key message for parents and teachers is that children vary in the precision of their intuitive sense of numbers. We might take for granted that every child perceives numbers with roughly comparable precision, but this assumption would be false. Some students may need more practice, or different kinds of practice, to develop this number sense,” Mazzocco said.

“At the same time, if a child is struggling with mathematics at school, we should not assume that the child’s difficulty is tied to a poor number sense; this is just one possibility.”
