Each child then took math ability tests consisting of  cheap authentic jerseys<a href="http://www.authentic-jerseys.cc/">cheap authentic jerseys </a>  numbering skills (verbally counting items on a page), numeral literacy (reading Arabic numbers), calculation skills (solving addition and subtraction problems) and other abilities.

Kids who did better at estimating the dots in the first test also did better at the math tests, the researchers found, suggesting that at least some math ability may be linked to one's inborn number sense. The study authors also gave the kids tests of general intelligence to rule out the possibility that those who did better on the math tests were simply those who performed well on all tests.

The  cheapest nfl jerseys<a href="www.authentic-jerseys.cc/NFL-Jerseys-c153//">cheapest nfl jerseys </a>  authors acknowledge the findings don't fully explain the link between number sense and math achievement in school. It's not clear, for example, whether kids with good number sense simply have an easier time learning math and thus do well in school. Or whether children with less-than-impressive number sense simply end up avoiding math-related activities early on, leading to poorer performance in school from lack of practice.

"Many questions remain and there is much we still have to learn about this," Libertus said.

The researchers hope their findings will be a jumping point for a deeper look into whether training can help kids improve their number sense, and hence their math performance.
