5-Minute Game May Improve Kids’ Math Skills

Sorry, moms and dads everywhere: video games (of a certain variety) might improve your child's math skills, at least for a short period of time. According to researchers at Johns Hopkins University, kids who spent five minutes playing a computer game scored significantly higher on math tests afterward. They published their results in the Journal of Experimental Child Psychology. 

Human beings may be the only animals lucky enough to take math tests, but many other species have an innate grasp of numbers. In scientific studies, salamanders, chickens, fish, and even venus flytraps have demonstrated an ability to count. And even before human babies can talk, they understand quantities. This vital knack for sizing up the world is known as an approximate number system, or ANS. This system is distinct from, say, algebra or long division, but it may make those processes easier for us to understand.

To find out, the researchers created a quick, simple ANS computer game involving colored dots. They recruited 45 kindergarten-age kids (16 girls and 24 boys) and brought them into the lab to play. 

In the game, the screen flashed two groups of dots, one blue and one yellow, for just 1200 milliseconds. (Previous studies suggested that an interval of 1200 milliseconds is long enough to see the dots clearly but not long enough to count them.) After each flash, each kid was asked to identify whether they had seen more blue dots or more yellow. Half of the kids started with relatively easy flashes, in which the difference between blue and yellow was obvious, and each successive flash got more difficult. The other group’s game started out hard and got progressively easier. 

After the game ended, half of the kids took an age-appropriate vocabulary test. The other half were given math questions taken from a standardized test. Five kids were knocked out of the study results because they bombed either the vocabulary (3 kids) or math tests (2 kids). 

Unsurprisingly, the kids’ vocab skills did not improve after the ANS game. But their math skills did. On average, the 10 kids in the easy-questions-first group scored in the 80th percentile on their math test. Those in the hard-questions-first group averaged in the 60th percentile. A third group of kids were tested at a later date, and their dot flashes were in random order. Their math scores averaged in the 70th percentile. In other words, basic ANS training, in which questions get progressively harder, boosted kids’ math scores—at least temporarily. 

Jinjing “Jenny” Wang is a JHU graduate student in psychology and lead author on the paper. “Math ability is not static,” she said in a press statement. “It’s not the case that if you’re bad at math, you’re bad at it the rest of your life. It’s not only changeable, it can be changeable in a very short period of time.”

With just 10 kids in each test group, this experiment had a very small sample size, but it’s a good place to start exploring these connections and what they might mean for learning.

Psychology and neuroscience researcher Lisa Feigenson is a co-author of the paper. “These results are really exciting to us because they show a very clear connection between an evolutionary set of abilities and a uniquely human set of formal math skills,” she says in the video above. “That raises lots of interesting questions, including how long this effect lasts and whether we can also improve children’s performance in a classroom setting.”

40 Educational Facts About Sesame Street

On November 10, 1969, television audiences were introduced to Sesame Street. In the near-50 years since, the series has become one of television's most iconic programs—and it's not just for kids. We're big fans of the Street, and to prove it, here are some of our favorite Sesame Street facts.

1. Oscar the Grouch used to be orange. Jim Henson decided to make him green before season two.

2. How did Oscar explain the color change? He said he went on vacation to the very damp Swamp Mushy Muddy and turned green overnight.

3. During a 2004 episode, Cookie Monster said that before he started eating cookies, his name was Sid.

4. In 1980, C-3PO and R2-D2 visited Sesame Street. They played games, sang songs, and R2-D2 fell in love with a fire hydrant.

5. Mr. Snuffleupagus has a first name—Aloysius.

6. Ralph Nader stopped by in 1988 and sang "a consumer advocate is a person in your neighborhood."

7. Caroll Spinney said he based Oscar's voice on a cab driver from the Bronx who brought him to the audition.

8. In 1970, Ernie reached #16 on the Billboard Hot 100 with the timeless hit "Rubber Duckie."

9. One of Count von Count's lady friends is Countess von Backwards, who's also obsessed with counting but likes to do it backwards.

10. Sesame Street made its Afghanistan debut in 2011 with Baghch-e-Simsim (Sesame Garden). Big Bird, Grover and Elmo are involved.

11. According to Muppet Wiki, Oscar the Grouch and Count von Count were minimized on Baghch-e-Simsim "due to cultural taboos against trash and vampirism."

12. Before Giancarlo Esposito was Breaking Bad's super intense Gus Fring, he played Big Bird's camp counselor Mickey in 1982.

13. Thankfully, those episodes are available on YouTube.

14. How big is Big Bird? 8'2".

15. In 2002, the South African version (Takalani Sesame) added an HIV-positive Muppet named Kami.

16. Six Republicans on the House Commerce Committee wrote a letter to PBS president Pat Mitchell warning that Kami was not appropriate for American children, and reminded Mitchell that their committee controlled PBS's funding.

17. Sesame Street's resident game show host Guy Smiley was using a pseudonym. His real name was Bernie Liederkrantz.

18. Bert and Ernie have been getting questioned about their sexuality for years. Ernie himself, as performed by Steve Whitmire, has weighed in: “All that stuff about me and Bert? It’s not true. We’re both very happy, but we’re not gay,”

19. A few years later, Bert (as performed by Eric Jacobson) answered the same question by saying, “No, no. In fact, sometimes we are not even friends; he can be a pain in the neck.”

20. In the first season, both Superman and Batman appeared in short cartoons produced by Filmation. In one clip, Batman told Bert and Ernie to stop arguing and take turns choosing what’s on TV.

21. In another segment, Superman battled a giant chimp.

22. Telly was originally "Television Monster," a TV-obsessed Muppet whose eyes whirled around as he watched.

23. According to Sesame Workshop, Elmo is the only non-human to testify before Congress.

24. He lobbied for more funding for music education, so that "when Elmo goes to school, there will be the instruments to play."

25. In the early 1990s, soon after Jim Henson’s passing, a rumor circulated that Ernie would be killed off in order to teach children about death, as they'd done with Mr. Hooper.

26. According to Snopes, the rumor may have spread thanks to New Hampshire college student Michael Tabor, who convinced his graduating class to wear “Save Ernie” beanies and sign a petition to persuade Sesame Workshop to let Ernie live.

27. By the time Tabor was corrected, the newspapers had already picked up the story.

28. Sesame Street’s executive producer Carol-Lynn Parente joined Sesame Workshop as a production assistant and has worked her way to the top.

29. Originally, Count von Count was more sinister. He could hypnotize and stun people.

30. According to Sesame Workshop, all Sesame Street's main Muppets have four fingers except Cookie Monster, who has five.

31. The episode with Mr. Hooper's funeral aired on Thanksgiving Day in 1983. That date was chosen because families were more likely to be together at that time, in case kids had questions or needed emotional support.

32. Mr. Hooper’s first name was Harold.

33. Big Bird sang "Bein' Green" at Jim Henson's memorial service.

34. As Chris Higgins put it, the performance was "devastating."

35. Oscar's Israeli counterpart is Moishe Oofnik, whose last name means “grouch” in Hebrew.

36. Nigeria's version of Cookie Monster eats yams. His catchphrase: "ME WANT YAM!"

37. Sesame Street's Roosevelt Franklin ran a school, where he spoke in scat and taught about Africa. Some parents hated him, so in 1975 he got the boot, only to inspire Gob Bluth’s racist puppet Franklin on Arrested Development 28 years later.

38. Our good friend and contributor Eddie Deezen was the voice of Donnie Dodo in the 1985 classic Follow That Bird.

39. Cookie Monster evolved from The Wheel-Stealer—a snack-pilfering puppet Jim Henson created to promote Wheels, Crowns and Flutes in the 1960s.

40. This puppet later was seen eating a computer in an IBM training film and on The Ed Sullivan Show.
