Adding math talk to story time at home is a winning factor forchildren's math achievement, according to a new research from the University ofChicago. The study from psychologists Sian Beilock and Susan Levine shows amarked increase in math achievement among children whose families used Bedtime Math, an iPad app that delivers engaging math story problems for parents and children to solve together.

    Even children who used the app with their parents as little as once a week saw gains in math achievement by the end of the school year. The app's effect was especially strong for children whose parents tend to beanxious or uncomfortable with math.

    Previous research from this group has demonstrated the importance of adults' attitudes about math for children's math success. For example, a recent study found that math-anxious parents who help their children with math homework actually weaken their children's math achievement.

    The new findings demonstrate that structured, positive interactions around math at home can cut the link between parents' uneasiness about math and children's low math achievement.

  “Many Americans experience high levels of anxiety when they haveto solve a math problem, with a majority of adults feeling at least some worries about math,” said Beilock, professor in Psychology andauthor of Choke, a book about stress and performance. “These math-anxiousparents are probably less likely to talk about math at home, which affects how competent their children are in math. Bedtime Math encourages a dialogue between parents and kids about math, and offers a way to engage in high-quality math interactions in a low-effort, high-impact way.”

    Study participants included 587 first-grade students and their parents. Families were given an iPad installed with a version of the Bedtime Math app, with which parents and their children read stories and answer questions involving math, including topics like counting, shapes and problem-solving. A control group received a reading app that had similar stories without the math content and questions related to reading comprehension instead. Children's math achievement was assessed at the beginning and end of the school year. Parents completed a questionnaire about their nervousness with math.

    The more times parents and children in the math group used the app, the higher children's achievement on a math assessment at the end of the school year. Indeed, children who frequently used the math app with their parents outperformed similar studentsin the reading group by almost three months in math achievement at year's end.

    Most people agree that eating healthy food is important. But sometimes making good food choices can be difficult. Now, there are apps that can help people learn about the food they eat to improve their health and their dining out experience.

    Open Table app

    Max McCalman's Cheese & Wine Pairing app

    Wine and cheese can be a great combination. But which wines go best with which cheeses? Max McCalman's Cheese & Wine Pairing app can help. It provides information about hundreds of different cheeses and suggests wines to pair with each. Max McCalman's Cheese & Wine Pairing app is free.

    HappyCow app

    Vegetarians do not eat animal meat. Vegans do not eat any animal products. The HappyCow app is made for both groups. Users can search for vegetarian-vegan restaurants and stores around the world.

    LocalEats app

    Restaurant chains, like McDonalds, can be found almost anywhere a person might travel. But sometimes travelers want to eat like locals. The LocalEats app is designed for that. It can help you find local restaurants in major cities in the US and in other countries. It costs about a dollar.

    Where Chefs Eat app

     “Where Chefs Eat” is a 975-page book. Most people would not want to carry that around. But there is a much lighter app version of the same name for just $15. Six hundred chefs provide information on 3,000 restaurants around the world on the Where Chefs Eat app.

    The story told to all American children about honesty is about the cherry tree that President George Washington cut when he was a boy. In China, every child knows the story of Lei Feng, the young soldier who helped others and was very honest. The stories of George Washington and Lei Feng help us understand the importance of being honest.

    Every teacher wants his or her students to be honest. If every student can be honest in their childhood, they will be honest when they become adults. The country will then be known as an honest country and it will be respected by everyone.

    Usually, it is the father and the mother who give the first lessons of honesty. George Washington learned honesty from his father.

    A favorite Chinese story is about a young man who went to the market to buy food for his mother. There was a very young girl there who was selling flowers. The young man stole one flower when the girl served her customer.

    When he went home, he began to think what he had done. He went back to the market to find the girl. He told her that he was sorry and that he wanted to pay her for the flower. The little girl refused and said, "You do not need to pay for the flower, elder brother. Since you took it, I thought you had a reason to take it so I did not worry about receiving money for it."The young man was ashamed that he stole the flower. He could never forget about the importance of being honest.

    "City Cycling USA: Los Angeles," a pocket-sized tour guide to seeing Los Angeles on two wheels, is seemingly for visitors; Actually, for locals, its series of bike-friendly paths and itineraries (行程) are a road-map to becoming tourists in their own city again.

    "City Cycling" explores five neighborhoods in the Westside and Eastside and generally north of the 10 and south of the 101. Itineraries fit the period of a day, beginning with spots for coffee, walking along museums and shops, and finishing off with recommendations of where to buy a well-deserved drink. Published by Thames and Hudson in association with London cycling brand Rapha Racing, the guidebook is among the first U.S. sections — alongside New York, Chicago and San Francisco — in a series launched in 2013 with biking tours of eight European cities.

    Greatest hits such as the Bradbury Building and Echo Park Lake are included in the neighborhood tours, with plenty of fashionable places for where to eat — Eggslut, Pine & Crane and Gjusta. The guide is a reminder of how crowdedly packed each enclave (飞地) of L.A. is with unusual destinations, the large number of places to explore within a few square mile radius (半径), easily done once we step out of the car.

    Los Angeles' famously pleasant weather makes it an ideal city for exploring by bike; neighborhoods have different styles. While the car still plays an important role, cycling culture, like CicLAvia, already has full support, and is prepared to grow with the implementation (实施) of Mobility Plan 2035, which aims to make the city more bike friendly. "City Cycling USA: Los Angeles" is a start.

    Two of the saddest words in the English language are “if only". I live my life with the goal of never having to say those words, because they convey regret, lost opportunities, mistakes, and disappointment.

    My father is famous in our family for saying, “Take the extra minute to do it right." I always try to live by the “extra minute" rule. When my children were young and likely to cause accidents, I always thought about what I could do to avoid an “if only" moment, whether it was something minor like moving a cup full of hot coffee away from the edge of a counter, or something that required a little more work such as taping padding (衬垫) onto the sharp corners of a glass coffee table.

    I don't only avoid those “if only" moments when it comes to safety. It's equally important to avoid “if only" in our personal relationships. We all know people who lost a loved one and regretted that they had foregone an opportunity to say “I love you" or “I forgive you." When my father announced he was going to the eye doctor across from my office on Good Friday, I told him that it was a holiday for my company and I wouldn't be here. But then I thought about the fact that he's 84 years old and I realized that I shouldn't give up an opportunity to see him. I called him and told him I had decided to go to work on my day off after all.

    I know there will still be occasions when I have to say “if only" about something, but my life is definitely better because of my policy of doing everything possible to avoid that eventuality. And even though it takes an extra minute to do something right, or it occasionally takes an hour or two in my busy schedule to make a personal connection, I know that I'm doing the right thing. I'm buying myself peace of mind and that's the best kind of insurance for my emotional well-being.

    Almost every night for more than 10 years, Kirk Alexander, 48, ordered a late dinner from his local restaurant Domino's Pizza. But for the past two weeks, he hasn't called for even once.

    "A few of my staff mentioned that we hadn't seen his order in a while. Then I found that it had been 12 days since he last ordered, which is not like him," Domino's general manager Sarah Fuller said, feeling she could no longer ignore Kirk's recent absence.

    Sarah has known Kirk since 2009 when she started working at the Domino's Pizza as a delivery driver (送餐员) and often made the short trip to Kirk's home about six minutes away. She knew Kirk worked from home, and neighbors said he seldom left. She also knew that he suffered some health problems in the past. Something, Sarah worried, was wrong.

    Around 1 a. m. on May 8, Sarah sent delivery driver Sean Hamblen to visit Kirk's home. Sean arrived at Kirk's home and knocked on the front door several times. There was no answer. He later noticed that the lights and the TV in the home were on. When he called Kirk's phone, it went straight to voice mail.

    Sean drove back to the restaurant to tell Sarah and they decided to call 911. Soon, officers arrived at Kirk's home. So did Sarah and Sean. They heard a man calling for help from inside. Officers broke down the door and found Kirk on the floor in need of medical attention at once after suffering from a heart attack (心脏病发作). One day later, they might have been too late.

    So is keeping an eye on regular customers (老顾客) part of Domino's business plan? Not really. "Kirk is part of our family here and we feel like we need to do something." Sarah said.
