A simple numbers game seems to make kids better at math.

Two colors dots flashed on a screen, and the children were asked to indicate whether there were more onesquickly, without counting.

Humans and animals are born with an intuitive sense of quantities and can demonstrate this knowledge as infants. For instance, when presented with a choice between a plate with a few crackers and another with more of them, even a baby will gravitate to the option with more. This intuition about number is called the "approximate number system."
