(AP) ? We know a lot about how babies learn to talk, and youngsters learn to read. Now scientists are unraveling the earliest building blocks of math ? and what children know about numbers as they begin first grade seems to play a big role in how well they do everyday calculations later on.

The findings have specialists considering steps that parents might take to spur math abilities, just like they do to try to raise a good reader.

This isn't only about trying to improve the nation's math scores and attract kids to become engineers. It's far more basic.

Consider: How rapidly can you calculate a tip? Do the fractions to double a recipe? Know how many quarters and dimes the cashier should hand back as your change?

About 1 in 5 adults in the U.S. lacks the math competence expected of a middle-schooler, meaning they have trouble with those ordinary tasks and aren't qualified for many of today's jobs.

"It's not just, can you do well in school? It's how well can you do in your life," says Dr. Kathy Mann Koepke of the National Institutes of Health, which is funding much of this research into math cognition. "We are in the midst of math all the time."

A new study shows trouble can start early.

University of Missouri researchers tested 180 seventh-graders. Those who lagged behind their peers in a test of core math skills needed to function as adults were the same kids who'd had the least number sense or fluency way back when they started first grade.

"The gap they started with, they don't close it," says Dr. David Geary, a cognitive psychologist who leads the study that is tracking children from kindergarten to high school in the Columbia, Mo., school system. "They're not catching up" to the kids who started ahead.

If first grade sounds pretty young to be predicting math ability, well, no one expects tots to be scribbling sums. But this number sense, or what Geary more precisely terms "number system knowledge," turns out to be a fundamental skill that students continually build on, much more than the simple ability to count.

What's involved? Understanding that numbers represent different quantities ? that three dots is the same as the numeral "3'' or the word "three." Grasping magnitude ? that 23 is bigger than 17. Getting the concept that numbers can be broken into parts ? that 5 is the same as 2 and 3, or 4 and 1. Showing on a number line that the difference between 10 and 12 is the same as the difference between 20 and 22.

Factors such as IQ and attention span didn't explain why some first-graders did better than others. Now Geary is studying if something that youngsters learn in preschool offers an advantage.

There's other evidence that math matters early in life. Numerous studies with young babies and a variety of animals show that a related ability ? to estimate numbers without counting ? is intuitive, sort of hard-wired in the brain, says Mann Koepke, of NIH's National Institute of Child Health and Human Development. That's the ability that lets you choose the shortest grocery check-out line at a glance, or that guides a bird to the bush with the most berries.

Number system knowledge is more sophisticated, and the Missouri study shows children who start elementary school without those concepts "seem to struggle enormously," says Mann Koepke, who wasn't part of that research.

While schools tend to focus on math problems around third grade, and math learning disabilities often are diagnosed by fifth grade, the new findings suggest "the need to intervene is much earlier than we ever used to think," she adds.

Exactly how to intervene still is being studied, sure to be a topic when NIH brings experts together this spring to assess what's known about math cognition.

But Geary sees a strong parallel with reading. Scientists have long known that preschoolers who know the names of letters and can better distinguish what sounds those letters make go on to read more easily. So parents today are advised to read to their children from birth, and many youngsters' books use rhyming to focus on sounds.

Likewise for math, "kids need to know number words" early on, he says.

NIH's Mann Koepke agrees, and offers some tips:

?Don't teach your toddler to count solely by reciting numbers. Attach numbers to a noun ? "Here are five crayons: One crayon, two crayons..." or say "I need to buy two yogurts" as you pick them from the store shelf ? so they'll absorb the quantity concept.

?Talk about distance: How many steps to your ball? The swing is farther away; it takes more steps.

?Describe shapes: The ellipse is round like a circle but flatter.

?As they grow, show children how math is part of daily life, as you make change, or measure ingredients, or decide how soon to leave for a destination 10 miles away,

"We should be talking to our children about magnitude, numbers, distance, shapes as soon as they're born," she contends. "More than likely, this is a positive influence on their brain function."

The Happiest US City Is ...

If you were thinking of a move, or even a weekend jaunt, perhaps a visit to Lincoln, Neb., would do the body and mind some good. The Star City scored highest in well-being in a newly released Gallup poll.

The results of the 2012 Gallup-Healthways poll, released today (March 26), were consistent with a state-level poll, which found the happiest U.S. states tended to be nestled in the Western and Midwestern parts of the country; the lowest well-being scores clustered in Southern states.

The poll was conducted through telephone interviews of more than 350,000 adults in 189 metropolitan areas, from Jan 2 until Dec. 29, 2012. To measure well-being, Gallup calculated an average of six measures: life evaluation (self-evaluation about present and future life situation); emotional health; work environment (such as job satisfaction); physical health; healthy behavior (such as frequent exercise and less smoking); and basic access (access to health care, a doctor, a safe place to exercise and walk, and community satisfaction). The same measures are used for state well-being.

Here are the top 10 cities and their average well-being scores (out of a possible 100 points):

  1. Lincoln, Neb.: 72.8
  2. Boulder, Colo.: 72.7
  3. Burlington-South Burlington, Vt.: 72.4
  4. Provo-Orem, Utah: 71.7
  5. Fort Collins-Loveland, Colo.: 71.6
  6. Barnstable Town, Mass.: 71.5
  7. Honolulu, Hawaii: 71.5
  8. Ann Arbor, Mich.: 71.4
  9. Washington-Arlington-Alexandria, (D.C.-Va.-Md.-W.V.): 71.3
  10. San Luis Obispo-Paso Robles, Calif.: 71.2

And here are the bottom 10 cities:

  1. Charleston, W.Va.: 60.8
  2. Huntington-Ashland, W.Va.-Ky.-Ohio: 61.2
  3. Mobile, Ala.: 62.4
  4. Beaumont-Port Arthur, Texas: 62.5
  5. Hickory-Lenoir-Morganton, N.C.: 62.7
  6. Fort Smith, Ark.-Okla.: 62.9
  7. Bakersfield, Calif.: 63.1
  8. Rockford, Ill.: 63.1
  9. Spartanburg, S.C.: 63.4
  10. Utica-Rome, N.Y.: 63.4

While Lincoln, Neb., led the nation overall and in the work environment category, Honolulu came out on top for emotional health, Charlottesville, Va., was No. 1 for physical health, and Salinas, Calif., had the healthiest behaviors.

Meanwhile, the Huntington-Ashland region (where West Virginia, Kentucky and Ohio meet) held its ignominious title as the metro area with the worst physical health. And it ranked second worst in terms of emotional health, only ahead of the country's least happy city, just a stone's throw away in Charleston, W.Va.

For the second year in a row, residents of Ann Arbor, Mich., had the most positive outlook for their current and future lives, while people living in the Hickory-Lenoir-Morganton region in North Carolina had a rather bleak attitude, rating their lives about half as well as those in Ann Arbor.

On the other side of Michigan's Lower Peninsula, in the Holland-Grand Haven area, residents had the best access to basic necessities in 2012, as they did in 2008-2010. The McAllen-Edinburg-Mission area in the southern tip of Texas ? where 50 percent of residents didn't have health insurance in 2012 ? ranked last in access to basic necessities for the fourth year in a row.

Among the 52 largest metro regions in the survey (those with over 1 million residents), the nation's capital and its surrounding area ranked highest for well-being, followed by the San Francisco-Oakland-Fremont area. Tampa-St. Petersburg-Clearwater, Fla., had the lowest well-being score of the nation's biggest cities (due mostly to low life evaluations and low happiness scores), displacing Las Vegas-Paradise, Nev., which ranked second worst for well-being in 2012.

Residents in cities with the best well-being scores tend to enjoy health benefits, such as lower rates of obesity, high blood pressure, diabetes and physical pain. They also are less likely to be depressed and more likely to have enough money for food, medicine and shelter, according to Gallup. Both public and private sectors can take part in improving well-being, for example, by providing access to healthy food, places where people feel safe working out, and health insurance ? or at least enough money to buy health insurance.

Whereas factors like health and access to basic necessities seem to have more obvious fixes, the happiness equation might be more elusive.

A study published in the December 2009 issue of the Journal of Research in Personality found that states with higher gross regional product (GRP) per capita (level of productivity and standard of living), higher income levels and higher median housing value were significantly happier than poorer areas. The study looked at Gallup's 2008 well-being scores, finding that the happiest states that year also tended to have more residents with advanced educations and jobs that were considered "super-creative," such as architecture, engineering, computer and math occupations, library positions, arts and design work, as well as entertainment, sports and media occupations. But then again, other studies have shown being happy means being old, male and Republican. Others yet have said the key is being religious or having kids.

The new Gallup results are based on telephone interviews conducted between Jan. 2 and Dec. 29, 2012, with a random sample of 353,563 adults, ages 18 and older, in all 50 U.S. states and the District of Columbia.
