The U.S. does not fare well in math when compared with other industrialized nations, as demonstrated by international tests like the PISA. So, for parents who want to help their students get ahead in math and can afford it, after-school programs that focus deeply on the subject have become attractive.

There are plenty of extracurricular math programs around, but one run by the Russian School of Mathematics (RSM) for students from kindergarten through 12th grade, is particularly popular, serving over 30,000 students around the country. (Innovation Hub senior producer, Elizabeth Ross, visited the program’s headquarters in Newton, Massachusetts and found a lot of enthusiastic students and parents, as you’ll hear in our report.)

Masha Gershman, the director of outreach at the Russian School of Mathematics and the daughter of one of its co-founders, says that the former Soviet Union’s method of math instruction has a lot to teach American kids, particularly when it comes to higher-level and conceptual learning.

But Jon Star, a professor at the Harvard Graduate School of Education, argues that many American parents - especially those in affluent suburbs where such extracurricular programs are popular - should ask themselves why they’re enrolling their kids in after-school math. It probably shouldn’t just be to get ahead in school - or to keep up with the neighbors. It should have to do with an intrinsic love of the subject.

Today, American voters are likely to describe issues about immigration as a major concern, and much of that concern began with a landmark commission a century ago. Author Katherine Benton-Cohen discusses how America transformed from a country with relaxed immigration policies to one with a massive, new immigration infrastructure.

Beer, airlines, retail, and many other industries are increasingly controlled by a few big players. The Brookings Institution’s David Wessel explains how corporate consolidation happens. And why it can lead to less competition, higher prices, lower wages... and less creative thinking.

When Amazon was looking for a home for its second headquarters, multiple cities and states offered billions of dollars in tax incentives to woo the company. But Nathan Jensen, a professor of government at the University of Texas, questions whether government incentives to attract big companies are worth it in the end.

First: Scurvy. Website design. Store promotions. Turns out, randomized trials affect many parts of our daily lives.

Then: The Origin of Species… actually has a pretty interesting - and unexpected - origin.

Finally: In news that shouldn’t shock anyone who has ever been to a meeting, they can make you less productive. But how about the toll they take even before they start?

Today, the Food Network is a touchstone of the entertainment industry. But it took a decade for the channel to make money. Chef Sara Moulton and author Allen Salkin tell us about the rise and influence of the cooking channel.

Plus: If you use Uber Eats more than you use your stove, you're in good company — 90 percent of Americans either don't like to cook or are on the fence about it. With cooking becoming more hobby than necessity, we look at how the food industry is trying to keep up.

Finally: 100 years ago, Schrafft's restaurants transformed dining out — by letting women eat with other women. Yale historian Paul Freedman talks with us about the restaurants that changed the way America eats.

First, a look at creative efforts to improve our health care system at the local level. Jon Gruber, an architect of the Affordable Care Act, and Sarah Kliff, a senior policy correspondent at Vox, discuss innovative steps that some states are taking to control health care costs and improve outcomes, including an effort to reduce the rate of premature birth.

Hotels have shaped American life from the Civil War to the civil rights movement. A.K. Sandoval-Strausz, author of “Hotel: An American History,” explains why the U.S. invented the modern hotel - and how the industry has influenced our country.

A potent issue dominated the midterms this fall: health care. It was a top concern for voters, and it ultimately shaped the outcome of races across the country. Jonathan Gruber, an economics professor at MIT and an architect of the Affordable Care Act, and Sarah Kliff, senior policy correspondent at Vox and host of the podcast The Impact, weigh in on the future of health care. With a divided Congress, Kliff and Gruber suggest that state governments and possibly the  private sector will be the places to watch for reform in the short-term.

After he was elected, President George Washington traveled through our newly-formed country. And along the way, he stayed at a series of inns and taverns. How did they stack up? Well, let’s just say our first president wasn’t much kinder than a modern-day disgruntled Yelp reviewer about his experiences. Washington wrote in his diary that he found, “No rooms or beds which appeared tolerable.”

While places to stay were rudimentary during Washington’s day, hotels eventually came to signify American progress. A.K. Sandoval-Strausz, an associate professor of history at Penn State and the author of “Hotel: An American History,” talks about how entrepreneurs in the early United States invented hotels, the hospitality industry, and how, in turn, hotels influenced American culture and commerce.

Whether you like it or not, our life is made of plastic. It’s a material we use for almost everything, from toothbrushes to spacecrafts. But its convenience and low costs might not outweigh the effects it has on our health and environment. Science journalist Susan Freinkel walks us through the history of how we fell in love with plastics and considers the risks they pose.

In the past, you might have seen your grandfather sending checks to a big charity every year, but charitable priorities are changing. Stacy Palmer, editor of the Chronicle of Philanthropy, explains how social, technological, and cultural changes have impacted who is giving and who is receiving... and just how much.

You’ve probably seen a “Made in China” label on your T-shirt, your electronics, and in children’s toys. But did you know that when you get your medicine from a local drug store, it may well have traveled all the way from China? Rosemary Gibson, author of “China Rx: Exposing the Risks of America’s Dependence on China for Medicine,” talks about how China became the world’s pharmacy, the risks posed by America losing control of its medicine supply, and the case for bringing some drug manufacturing back to the U.S.

Plastics are colorful, shiny, and flexible. They can also be sturdy, monochrome, and opaque. They come in different shapes and sizes, too. In fact, we’ve become so good at creating and molding plastics into whatever we want them to be that author Susan Freinkel says: it’s hard to imagine a world without them. In her book, Plastics: A Toxic Love Story, Freinkel chronicles the history of plastics and explores how, for better or worse, the material shapes our lives.

The Chronicle of Philanthropy has long kept tabs on charitable giving, but recently the publication unveiled a new ranking, which reveals that how we give and who is giving has been radically upended in America.

Stacy Palmer, the editor of the Chronicle of Philanthropy, discusses the current trends in giving and what they reveal about our country - including the growing economic divide in the wake of the Great Recession. And she offers some advice about how to choose causes that make a real difference.
