(Sound effect: kids playing) Kids by the Numbers.
I'm Bob Karson with the discovery files -- new advances in science and engineering from the National Science Foundation.
New study out of the University of Chicago that says you may have a big impact on your child's understanding of mathematics -- if as toddlers you simply talk to them more about numbers. What -- a little Pythagorean theorem with their pablum? No, just simple numbers-based references in everyday situations -- like saying "there are three blocks on the floor." Most toddlers can spout back a string of numbers but eventually having them recognize a set of three is more abstract and much more valuable to their overall understanding.
The study showed that while they might not always grasp the total concept, simply exposing the child to more number references seems to help them make connections and get a leg up on their peers who aren't getting as much number talk.
The team studied tapes of parents individually interacting with their child for about 90 minutes. Some had as few as four number references in that time -- others as many as 257. When tested later, the kids with more number references from parents were more likely to respond correctly when shown a set of, say, five squares and four squares, and asked to "point to five."
Previous tests have shown that by the time children enter preschool, they already show marked individual differences in their mathematical knowledge. This new research points out that early number talk may really count in their development.
By the way, we're brought to you today by the number five.
