How to make your Kid a Math Smart whole Life?

Kid Math Smart in Life, Early you learn better for whole life


This research has open new venues for building a strong foundation in kids for math study. Math is very important to subject which will make them excel in their life.

New Research- First grade math skills set foundation for later math ability

 

Children who failed to acquire a basic math skill in first grade scored far behind their peers by seventh grade on a test of the mathematical abilities needed to function in adult life, according to researchers supported by the National Institutes of Health. The basic math skill, number system knowledge, is the ability to relate a quantity to the numerical symbol that represents it, and to manipulate quantities and make calculations. This skill is the basis for all other mathematics abilities, including those necessary for functioning as an adult member of society, a concept called numeracy.

The researchers reported that early efforts to help children overcome difficulty in acquiring number system knowledge could have significant long-term benefits. They noted that more than 20 percent of U.S. adults do not have the eighth grade math skills needed to function in the workplace.
An early grasp of quantities and numbers appears to be the foundation on which we build more complex understandings of numbers and calculations,” said Kathy Mann Koepke, Ph.D., director of the Mathematics and Science Cognition and Learning: Development and Disorders Program at the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD), the NIH institute that sponsored the research. “Given the national priority on education in science, technology, engineering and math fields, it is crucial for us to understand how children become adept at math and what interventions can help those who struggle to build these skills. Senior author David C. Geary, Ph.D., of the University of Missouri, Columbia, conducted the research with colleagues Mary K. Hoard, Ph.D., and Lara Nugent, and with Drew H. Bailey, Ph.D., of Carnegie Mellon University, Pittsburgh. The study appears online in PLoS One. These results are part of a long-term study of children in the Columbia, Mo., school system. Initially, first graders from 12 elementary schools were evaluated on their number system knowledge. Number system knowledge encompasses several core principles:

•Numbers represent different magnitudes (five is bigger than four).
•Number relationships stay the same, even though numbers may vary. For example, the difference between 1 and 2 is the same as the difference between 30 and 31.
•Quantities (for example, three stars) can be represented by symbolic figures (the numeral 3).
•Numbers can be broken into component parts (5 is made up of 2 and 3 or 1 and 4).

The researchers also evaluated such cognitive skills as memory, attention span, and general intelligence.
The researchers found that by seventh grade, children who had the lowest scores on an assessment of number system knowledge in first grade lagged behind their peers. They noted that these differences in numeracy between the two groups were not related to intelligence, language skills or the method students used to make their computations. For the testing at age 13, 180 of the students took timed assessments that included multiple-digit addition, subtraction, multiplication, and division problems; word problems; and comparisons and computations with fractions. Previous studies have shown that these tests evaluate functional numeracy―skills that adults need to join and succeed in the workplace. This might include the limited understanding of algebra needed to make change such as being able to provide an answer to a question such as: “If an item costs $1.40 and you give the clerk $2, how many quarters and how many dimes should you get back?” Other aspects of functional numeracy include the ability to manipulate fractions, as when doubling the ingredients in a recipe (for example, adding 1 ½ cups water when doubling a recipe that calls for ¾ cups water) or finding the center of a wall when wanting to center a painting or a shelf.

The researchers’ analysis showed that a low score on the assessment of number system knowledge in first grade significantly increased a student’s risk of getting a low functional numeracy score as a teenager. The researchers examined learning and found that first graders with the lowest scores also had the slowest growth in number system knowledge throughout that school year. Starting with poor number knowledge can put children so far behind that they never catch up, the researchers said.
These findings are especially valuable for bringing attention to the idea that numeracy early in life has profound effects not only for the individual, but also for the society that individual works and lives in,” Dr. Mann Koepke said.

Why C-Section Babies More Likely To Develop Allergies

This study gives us one more reason that C-section is not good for mother but also not good for kids.

What is C section?

Cesarean delivery — also known as a C-section — is a surgical procedure used to deliver a baby through an incision in the mother's abdomen and a second incision in the mother's uterus.
A C-section might be planned ahead of time if you develop pregnancy complications or you've had a previous C-section and aren't considering vaginal birth after cesarean (VBAC). Often, however, the need for a first-time C-section doesn't become obvious until labor is under way.
If you're pregnant, knowing what to expect during a C-section — both during the procedure and afterward — can help you prepare

Why it's done?

Sometimes a C-section is safer for you or your baby than is a vaginal delivery. Your health care provider might recommend a C-section if:
Your labor isn't progressing.
Stalled labor is one of the most common reasons for a C-section. Perhaps your cervix isn't opening enough despite strong contractions over several hours — or the baby's head is simply too big to pass through your birth canal.
Your baby isn't getting enough oxygen
If your health care provider is concerned about your baby's oxygen supply or changes in your baby's heartbeat, a C-section might be the best option.
Your baby is in an abnormal position
A C-section might be the safest way to deliver the baby if his or her feet or buttocks enter the birth canal first (breech) or the baby is positioned side or shoulder first (transverse).
You're carrying twins, triplets or other multiples
When you're carrying multiple babies
 it's common for one or more of the babies to be in an abnormal position. In this case, a C-section is often safer.
There's a problem with your placenta
If the placenta detaches from your uterus before labor begins (placental abruption) or the placenta covers the opening of your cervix (placenta previa),
 C-section might be the safest way to deliver the baby
There's a problem with the umbilical cord
A C-section might be recommended if a loop of umbilical cord slips through your cervix ahead of your baby or if the cord is compressed by the uterus during contractions.
You have a health concern
Your health care provider might suggest a C-section if you have a medical condition that could make labor dangerous, such as unstable heart disease or high blood pressure. In other cases, a C-section might be recommended if you have an infection that could be passed to your baby during vaginal delivery — such as genital herpes or HIV.
Your baby has a health concern
A C-section is sometimes safer for babies who have certain developmental conditions, such as excess fluid in the brain (hydrocephalus).
You've had a previous C-section
Depending on the type of uterine incision and other factors, it's often possible to attempt a vaginal delivery after a previous C-section. In some cases, however, your health care provider might recommend a repeat C-section.
Recovery from a C-section takes longer than does recovery from a vaginal birth.
And like other types of major surgery, C-sections also carry a higher risk of complications.

Risks to your baby include:

Breathing problems
Babies born by C-section are more likely to develop transient tachypnea — a breathing problem marked by abnormally fast breathing during the first few days after birth. C-sections done before 39 weeks of pregnancy or without proof of the baby's lung maturity might increase the risk of other breathing problems, including respiratory distress syndrome — a condition that makes it difficult for the baby to breathe.
Surgical injury
 Although rare, accidental nicks to the baby's skin can occur during surgery.
Risks to mother
Inflammation and infection of the membrane lining the uterus
This condition — known as endometritis — can cause fever, foul-smelling vaginal discharge and uterine pain.
Increased bleeding
 You're likely to lose more blood with a C-section than with a vaginal birth. Transfusions are rarely needed, however.
Reactions to anesthesia
Adverse reactions to any type of anesthesia are possible. After an epidural or spinal block — common types of anesthesia for C-sections — it's rare, but possible, to experience a severe headache when you're upright in the days after delivery.
Blood clots
The risk of developing a blood clot inside a vein — especially in the legs or pelvic organs — is greater after a C-section than after a vaginal delivery. If a blood clot travels to your lungs (pulmonary embolism), the damage can be life-threatening. Your health care team will take steps to prevent blood clots. You can help, too, by walking frequently soon after surgery.

What are Babies Allergies?

It’s important to introduce baby to new foods gradually, and one at a time, in case of food allergies. Otherwise, you’ll have trouble tying an allergy to a specific new food. For example, if you give your baby three new foods over the course of a day and she develops an allergic reaction, you won’t know which of the foods provoked it.
It doesn’t matter all that much which foods you introduce to your baby, or which order you introduce them in, as long as the foods you are offering are healthy and well-balanced. But each time you offer a new food, you should wait three to five days before adding another to the menu. Don’t eliminate all the other foods your baby is already eating during that time -- just don’t add anything else new.

The Top 8 Allergenic Foods

With each new food, you’ll want to be on the lookout for allergic reactions. There are more than 160 allergenic foods, but these eight foods and food groups are the culprits 90% of the time. You may want to wait until baby is older to try some of these foods, especially peanuts. In fact, many experts suggest waiting until your child is 3 before trying peanuts. Ask your pediatrician if you have any questions about a food.
 
Milk
Egg
Peanuts
Tree nuts (such as walnuts or almonds)
Fish
Shellfish
Soy
Wheat

Food Allergy Symptoms to Watch for in Your Baby

Food allergy symptoms usually appear very soon after the food is eaten -- within a few minutes to a couple of hours. If you’re introducing a new food to your baby, keep an eye out for these symptoms:
Hives
Flushed skin or rash
Face, tongue, or lip swelling
Vomiting and/or diarrhea
Coughing or wheezing
Difficulty breathing
Loss of consciousness

Severe Food Allergy Symptoms: When to Call 911

If your baby is having trouble breathing, has swelling on her face, or develops severe vomiting or diarrhea after eating, don’t take time to call your pediatrician. Call 911 immediately. Severe allergic reactions can be fatal very quickly

New Research-C-Section Babies 5 Times More Likely To Develop Allergies


C-section babies are five times more likely to develop allergies by age two than those born naturally. The finding came from a new study conducted by researchers from Henry Ford Hospital and was presented at the American Academy of Allergy, Asthma, and Immunology yearly meeting in San Antonio.

 The findings coincide with previous research which demonstrated that babies born by C-section are more likely to have asthma than babies delivered naturally. A different report showed that caesarean section babies have an increased risk of food allergies and diarrhea during their first year of life. The new report indicated that C-section (cesarean section) babies are more vulnerable to allergies. They found that the chance of developing allergies for C-section babies is five times greater than for those born naturally when exposed to high levels of common allergens in the home, including those from cats, dogs, and dust mites. Leading author Christine Cole Johnson, Ph.D., MPH, chair of Henry Ford Department of Health Sciences, said, “This further advances the hygiene hypothesis that early childhood exposure to microorganisms affects the immune system's development and onset of allergies. We believe a baby's exposure to bacteria in the birth canal is a major influencer on their immune system.
In the gastrointestinal tract of babies born by C-section, there is a pattern of "at risk" microorganisms that may cause them to be more vulnerable to developing the antibody Immunoglobulin E, or IgE, when in contact with allergens, according to Dr. Johnson. It is known that IgE is associated with the development of asthma and allergies. For the purpose of the study, the experts at Henry Ford set out to assess the role of early exposure to allergens and analyze how this exposure has an impact on the link between C-section and the development of IgE. A total of 1,258 newborns were involved in the investigation from 2003 until 2007 and were assessed at 4 different times: at one month old, six months, one year, and two years.

The researchers gathered data from:
The baby's umbilical cord and stool
Breast milk
Household dust
Blood samples from the baby's mother and father
Family history of allergy or asthma
Household pets
Tobacco smoke exposure
Medication use
Baby illnesses
Pregnancy variables
The research received funding from Henry Ford Hospital and National Institute of Allergy and Infectious Diseases.

How to Avoid Common Health and Fitness Blunders Part II

Avoid Common Health and Fitness Blunders

This is my second part of blog on Avoiding Common Health and Fitness Blunders. In this blog you will see some more Health and Fitness Blunders we all must avoid to have better life

Health and Fitness Blunder #5: You think you are working hard, but you can talk to the person on the treadmill next to you without discomfort.


Intensity is one of the hardest things for many exercisers to understand. You don’t want to work so hard that you become exhausted early in your workout, but you also don’t want to take it so easy that you don’t break a sweat. There are a few simple ways to determine your intensity and help you decide if you need to step it up a bit


1. At the height of your workout, you should be sweating and breathing hard. Use the "Talk Test" to measure your intensity. You should be able to answer a question, but not comfortably carry on a conversation. If you can walk on the treadmill and easily tell your friend all about your day, you are not working hard enough, so step it up!


2. Another great way to measure your intensity is with a heart rate monitor or by checking your heart rate periodically. There is an easy formula to calculate your Target Heart Rate, which will tell you if you are working at the right intensity.

Working at a high intensity will help you burn the most calories in the shortest amount of time, making your workout as efficient as possible.


Health and Fitness Blunder #6: Since you exercise, you figure you can eat whatever you want


The key to weight loss is a healthy diet and regular exercise program. It is very difficult to lose weight through exercise alone. Those extra calories add up quickly and might take longer than you think to burn off by working out.

For example, you decide to treat yourself to medium popcorn (with butter, of course) at the movies. You did a 45-minute workout on the treadmill this morning, so you deserve it, right? Well, you might want to think before you eat. You probably burned about 400 calories on the treadmill, but that tub of popcorn contains almost 1200 calories!! So you would have to do an extra 90-minute workout just to burn off your movie treat. When you think about it that way, a better option might be to skip the popcorn and bring a granola bar or other healthy snack.

One thing you can do to prevent mistakes from happening to you, is to ask questions! The Resident Experts are always happy to help you make the most of your workouts and answer any questions you might have. 

 

Health and Fitness Blunder #7: Believing the Myths


There are too many to count. Fitness myths are created for many reasons, but are mainly the result of people unknowingly spreading inaccurate information. Sometimes they are blatant sales approaches to try to get you to buy the latest book, training sessions, or exercise contraption.

There is no miracle solution. The great thing about exercise, just like life, is that there are many different ways to success. Figure out a way that works for you, but don’t fall into the trap and believe these myths.

 

Myth #1: You will burn more body fat if you exercise at a slower intensity


I’m not sure how this started. Maybe the theory behind it believes that exercising at a slow intensity will help you sustain your exercise and create consistency-- which, again, is very important. The problem is you will only condition yourself at a very low level, which won’t help you burn the necessary calories you need to lose weight. Yes, it’s good to start out with this theory in mind so you don’t burn yourself out. But it’s paramount that you increase your intensity over time.


Myth #2: Use light weight to tone your muscles


This always seems to imply that you shouldn’t lift more than what you consider "light". Maybe it’s 5, 10, or even 15 pounds, but you shouldn’t necessarily put a limit on what you should lift. Instead you should put a minimum and maximum on how many times you perform an exercise. Weight should always be relative to how many repetitions you can do. If you can only do 4-6 reps with proper form, the weight is too heavy. If you can do 15-20 reps and feel like you could easily do more, even if you are lifting 100 lbs, you are using a weight that is too light. This doesn’t mean you have to push yourself so hard that you don’t want to ever exercise again. But you should push yourself to the point where you couldn’t do another rep without breaking form the majority of the time if you want to achieve a toned body. Of course, beginners are recommended to work your way up to this point.

 

Myth #3: Abdominal exercises will help get rid of the fat around your belly


The key to lowering your body fat is burning calories. The best way to torch calories is through cardio. The core muscles are very important to strengthen but unfortunately you don’t burn many calories by working them. Therefore, spending most of your exercise time each workout on abdominal exercises doesn’t make sense. You will burn many more calories and lose overall body fat in all areas of your body by working your larger muscle groups… quadriceps, upper back, chest, shoulders and hamstring/buttocks. Riding a bike, running on a treadmill, or doing the elliptical works all of these large muscle groups, but it’s also important to add a bit more resistance with strength training exercises.


Myth #4: You have to be an athlete to exercise


Exercise has always been linked directly with athletes because it helps them condition themselves to improve their performance. Unfortunately, exercise hasn’t been linked with the improvement of everyday life as much as it should. Every person benefits from exercise. There are hundreds, if not thousands of different ways to exercise… find the right training that links to your lifestyle.

Health and Fitness Blunder #8: Not Being Consistent


One of the biggest blunders of an exercise program is the lack of consistency. It’s very similar to climbing a mountain. There may be all sorts of reasons why you want to climb your "mountain"— to lose weight, to gain energy, to improve health, or to fit into your favorite jeans.

You exercise for 2 weeks, and then you have to work overtime, so you take a whole week off. You get back to the gym for another week, and you’re feeling great. A couple days later, you have to go to your son’s basketball game, and a few days later, your parents are in town for the weekend. Your exercise quickly falls low on the priority list. Does this sound familiar? You might get over the foothills of your mountain with this approach, but there’s no chance you’ll ever see that beautiful view you have in your mind.

Does that mean you have to exercise every day to be consistent? NO! It means that you need a plan that incorporates fitness into your weekly schedule. This way you continue to climb upwards. The key is not letting you tumble back down to the bottom, so even holding steady or just taking one step forward is enough.

Maybe your forward progress starts with 2 days of exercise for 20 minutes until you reach the foothills. Yes, it might take you longer to get over the foothills this way, as opposed to working out 6 days a week for an hour, but it’s a process that allows you to adapt and adjust your current lifestyle to incorporate change for the long haul. When you're ready to tackle that first small mountain, bump it up to 3 days of exercise for 25 minutes. You can actually enjoy the process because it doesn't take everything out of you to get this far and you find yourself excited to add to your program. This excitement is the motivation that will eventually lead you as far as you want to go. A good view to shoot for is 5 days a week for at least 30 minutes.

At some point something will come up in life that knocks you back down a little bit. It’s only natural that your excitement level can plummet when this happens. But if you expect it and are prepared, you can limit the impact it has on your climb. All the successful climbers understand it’s part of the process. They LEARN from whatever knocks them back so it doesn’t hurt them again at another point along the journey.

Learning how to overcome a tumble, slowly building on your plan, and using excitement as motivation are keys to making exercise a part of your lifestyle. This lifestyle will help you climb that mountain and enjoy the view from the top. From there, it’s all about maintenance.


Have you ever started a workout routine, thinking you’re doing everything right, only to find out there were some important things you missed? Here are some common workout mistakes that most of us have made from time to time, and what you can do to prevent them from happening to you.
