Mathieu Ossendrijver of Humboldt University in Berlin found the tablet while combing through the collections at the British Museum. The written record gives instructions for estimating the area under a curve by finding the area of trapezoids drawn underneath. Using those calculations, the tablet shows how to find the distance Jupiter has traveled in a given interval of time. Until now, this kind of use of trapezoids wasn't known to exist before the 14th century. ... By 400 B.C. Babylonian astronomers had worked out a coordinate system using the ecliptic, the region of the sky the sun and planets move...

The largest prime number in the world has been discovered in Missouri by the Great Internet Mersenne Prime Search project, better known as GIMPS. The record breaking number â€” which, like all primes, can only be divided by itself and one â€” is a staggering 22 million digits in length. That's 5 million digits longer than the previous recordholder, which was also discovered by GIMPS back in January 2013. If you really want to know, the new biggest Prime in the world starts with a "3" and ends with a "1."

Another Common Corealigned math problem is going viral. This time a 3rd grade math problem was marked as incorrect even though the student found the correct answer. On the other hand, submissions with the wrong answer have been counted right. The question asked the student to find the result of 5 multiplied by 3, using the "repeated addition strategy." The student wrote "5+5+5" and correctly found the answer to be 15. Apparently, this strategy didn't fit with the Common Coreestablished method for teaching multiplication, so the teacher punished the student for getting the right answer in a way not prescribed....

The OECD is out with new global rankings of how students in various countries do in reading , science and math .

It's a notso rosy report card for the nation's schoolchildren. Math scores slipped for fourth and eighth graders over the last two years, and reading grades were not much better, flat for fourth graders and lower for eighth graders, according to the 2015 Nation's Report Card. ... Education Secretary Arne Duncan urged parents, teachers, and others not to panic about the scores as states embrace higher academic standards, such as Common Core.

A new trend in math at elementary schools around the country has parents pulling out their hair. Mainly because it is the opposite of how most of today's adults were taught to do simple multiplication in the first place. According to a Common Core math worksheet that's gone viral, an elementary child today cannot just say, "5 x 3 = 15." Instead they have to change the multiplication problem to addition before solving the equation. However, if the child says, "5 + 5 + 5 = 15," they will still lose points because the problem must be written as it...

Here's a "repeated addition" Common Core problem that's taught in third grade in US schools: Use the repeatedaddition strategy to solve: 5x3 If you answer the question with "5+5+5=15,” you would be wrong. The correct answer is "3+3+3+3+3.” Mathematically, both are correct. But under Common Core, you're supposed to read "5x3" as "five groups of three." So "three groups of five" is wrong. According to Common Core defenders, this method will be useful when students do more advanced math. This way of reading things, for instance, can be used when students learn matrices in multivariable calculus in high school. But...

California Sen. Holly Mitchell (D) connects the lack of racial diversity in Silicon Valley with racially motivated Â“math misplacement.Â”She claims middleschool algebra teachers are holding back black and Latino kids from advancing to ninthgrade geometry, even though they are doing just as well as white kids who are getting a grade of Â“BÂ” or better, and are meeting or exceeding state standard assessments.However, the study that Mitchell and others supporting her effort cite as proof of their position also shows the real problem is actually with middleschool algebra teachers. Many of them just arenÂ’t very good at their jobs.The...

Washington  There has been an astounding 32 per cent increase this year in the number of students flocking to American universities for higher studies. It is the biggest increase from any single country for the year, although in overall terms, China still tops the table in a big way. Figures just released by the US Student and Exchange Visitor Programme (SEVP) indicate that 149,987 Indian students are currently enrolled in American universities of a total of 1.05 million. Chinese students number 301,532. When it comes to the highlycoveted STEM (Science, Technology, Engineering and Math) stream, it is Indian students...

What Is the Math of Spiritual Goods and Why Is The World Such a Deadly Place Without It? Msgr. Charles Pope â€¢ August 10, 2015 â€¢ In an increasingly materialistic and secular world, a deadly math has set up. It is deadly because it has rejected the spiritual math of God and of spiritual goods.What is meant by Â“spiritual mathÂ”? It is a math that recalls that spiritual goods, in themselves, do not admit of division and subtraction, but only of multiplication and addition. Rather than diminishing, spiritual goods grow when shared. And this is a critical math never to...

The New York State Education Department released a sampling of questions from statewide math and reading tests this week, showing the kind of problems elementary and middleschool students have to grapple with. As The New York Times notes, New York is generally considered to have some of the hardest tests in the country. Only 36% of students passed the math exams in 2014; reading scores were even lower. Along with some of the questions that appeared on each test, NYSED included the percentage of students statewide who answered the question correctly. Scores of individual schools will be released later this...

In a recent ABC News article, journalist David Knight writes that two German scientists have proven logician and mathematician, Kurt Gödel’s, theorem for God’s existence is logically accurate [1]. Knight writes, “The details of the mathematics involved in Gödel's ontological proof are complicated, but in essence the Austrian was arguing that, by definition, God is that for which no greater can be conceived. And while God exists in the understanding of the concept, we could conceive of him as greater if he existed in reality. Therefore, he must exist. “Even at the time, the argument was not exactly a new...

John Urschel plays football for the Baltimore Ravens. He's also a published mathematician. How does he stack up against the average millennial?

In recent months, Christopher Scalia in the Wall Street Journal and Fareed Zakaria in the Washington Post have defended studying the liberal arts in college, primarily to confront advocates of science, technology, engineering, and mathematics (STEM). Zakaria’s article previewed his new book, “In Defense of a Liberal Education.” From my perspective as a former engineer, two caveats arise regarding their pleas: first, “liberal” education that involves “critical thinking” disappeared decades ago, to be replaced by hypersensitive grievance mongering; second, the quantitative reasoning STEM occupations develops also facilitates the understanding of tradeoffs people need to make rational decisions among myriad conflicting...

John Forbes Nash Jr. was a mathematical genius who had his life chronicled in the movie A Beautiful Mind. One of Nash’s colleagues says that just days before he died in a New York taxi cab accident, he had discussed his latest and possibly most brilliant discovery to date. Mathematician Cédric Villan says that Nash told him that he had replaced Einstein’s Theory of Relativity and that the new equation would further explain quantum gravity. The Daily Mail reports that on May 20, 2015, just three days before the tax cab accident that would take his life, Nash spoke to...

I'm trying to figure something out for work, but my math skills are not very good. How do I calculate percentages if an event reoccurs multiple times? Suppose there is an event that has the chance of occurring on in 6 times (like rolling a dice and getting a "five"). What are the chances I will get a "five" if I roll the dice six times?

TORONTO, April 24, 2015  A lesbian teacher ‘married’ to another woman revealed at a progay teachers’ conference earlier this month how she teaches grade 45 students to accept homosexuality through what she called “social justice” math. Alicia Gunn, an elementary public school teacher in Mississauga, Ontario, told attendees at the April 10 conference in Toronto’s City Hall that injecting LGBTQ issues into the classroom, especially in math, helps students as young as nine “disrupt the single story that many of our kids have about LGBTQ families.” When asked by one of the workshop attendees if she first asks parents’...

NEW DELHI (AP) — An Indian bride walked out of her wedding ceremony after the groom failed to solve a simple math problem, police said Friday. The bride tested the groom on his math skills and when he got the sum wrong, she walked out. The question she asked: How much is 15 plus six? His reply: 17.

At 10 years old... Esther Okade... is more interested in writing an algebra workbook for kids and studying for college exams. Esther, a BritishNigerian homeschooled student, started in January as a freshman at the distance learning college Open University, making her one of the youngest college students in England. “I actually wanted to start when I was seven,” she told CNN. “But my mum was like, ‘you’re too young, calm down.’” Math is Esther’s strong suit and according to her mother Efe Okade, she’s had an unusual grasp of numbers since she was barely old enough to read. “At four,...

As schools adopt new education standards and rely more on computers in the classroom, a group of New Hampshire senators want to make sure the basics of learning cursive and multiplication tables don’t get left behind. “You definitely need to teach typing and keyboarding and all of that, but kids do need to be able to sign their names, they do need to be able to read the Founding Fathers documents,” said Republican Sen. Nancy Stiles, the main sponsor of a bill that would require public schools to keep teaching both. “(Cursive) is an art and a skill that shouldn’t...

Trigonometry Is Racist! KEVIN D. WILLIAMSON February 27, 2015 An AfricanAmerican scholar says that emphasis on STEM education is bad for blacks. Earlier today on Sirius XM Urban View, an AfricanAmerican talk station, the guest was Daryl Scott, president of the Association for the Study of African American Life and History. The conversation turned to STEM — science, technology, engineering, and math — education, and the origins of the ongoing push to encourage institutions and students to focus on those subjects. Can you guess what happened? In 1983, the guest explained, a commission empaneled by the secretary of education issued...

Michael Petrilli of the Thomas B. Fordham Institute has nine question for Common Core opponents, which I would like to answer with eight questions of my own. First, Mr. Petrilli: 1. Do you mean that you oppose the Common Core standards themselves? All of them? Even the ones related to addition and subtraction? Phonics? Studying the nation’s founding documents? Or just some of them? Which ones, in particular, do you oppose? Have you actually read the standards? 2. Or do you mean that you oppose the role that the federal government played in coercing states to adopt the Common Core?...

Wendy Davis made herself a progressive champion by running as an outspoken progressive in a really conservative state, with the predictable result that she lost really, really badly. Salon’s Jenny Kutner, a strong Davis supporter, concedes that Davis did, in fact, lose. What Kutner refuses to concede is that Davis lost among women: The Tribune cited CNN exit polls to illustrate the landslide, saying Abbott “beat Davis by lopsided margins with white voters (7227), men (6534) and women (5247). Davis beat Abbott among Latinos (5742) and AfricanAmericans (937).” Last time I checked, though, there were thousands upon thousands of women...

On the last day of the 2014 campaign, Democrats knew they were in trouble.

On both coasts, grandparents are learning to apply a modernday rule of thumb with surprising accuracy: If it looks inane, it’s probably Common Core. “The Berkeley school district's curriculum for sixthgrade math was an exact copy of the Common Core State Standards for the grade,” Marina Ratner wrote in The Wall Street Journal on August 5, 2014. “The teacher in my grandson's class went through special Common Core training courses.” “As his assigned homework and tests indicate, when teaching fractions, the teacher required that students draw pictures of everything: of 6 divided by 8, of 4 divided by 2/7, of...

DENVER — Results for a new standardized test for science and social studies came in on Monday and they likely put frowns on educators and parents. ...

For example, in fourthgrade social studies, 6 percent of Hispanic/Latino students and 7 percent of AfricanAmerican students have “strong” or “distinguished command” of the subject....

Among the 34 OECD countries, the US performed below average in mathematics and is ranked 27th ... While the U.S. spends more per student than most countries, this does not translate into better performance (e.g. the Slovak Republic, which spends around $53k per student, performs at the same level as the US, which spends over $115k per student).

When is the wrong answer the right answer? Now. Today. Reality alert: we have entered an alternative universe, thanks to Common Core. As people once scorned wrong answers, we will now learn to scorn right answers. Answergetting (that’s the new jargon) will be held up for contempt, and slowly eliminated. That’s the plan. This is not marginal nonsense. No, it is already mainstream nonsense. Phil Daro is one of the three principal writers of the Common Core Mathematics Standards. A 17minute video about his ideas is promoted this way: “Phil Daro goes into detail on the problems of ‘Answergetting,’ one...

In an intentional attempt to study and potentially confuse children, children were asked "There are 25 sheep and 5 dogs in a flock. How old is the shepherd?" Why might you ask this supposedly commoncore aligned question? According to the teachers who created this problem, it is to teach students that they must: 1. Explain the meaning of a problem. 2. Plan a solution pathway rather than simply jumping into a solution attempt. 3. Continually ask themselves, "Does this make sense?" This question has actually been researched for years, and is still being asked to children. Today, however, it is...

The other day, an English professor (retired) showed me a story in a magazine and corrected an interesting grammatical issue he found there. I at first thought he was crazy, but now I’m pretty sure he’s correct. After all, he’s the prof’. Here it is: When we speak of numbers, certain words always translate to mathematical formulas. “Less” means subtract. “There were ten, now there are three less.” 103. Duh. “Times” means multiply. “Of” means multiply. “How many cars were there?” “There were 10 of them.” 10 “OF” cars means 10 X 1.” Or… “I had half OF the six...

Imagine a teacher asks you to solve this question: 568293. Depending on your age you might do one of three things... ...Third, you might use the new common core was to subtract, which is much simpler, with only... 10 steps. First, you would take the 200 out of the 293, and save the 93 for later. Then you would take 568 and subtract 200 from it. Then you'd take the remaining 368 and you would subtract 60 from it, because you are taught that, for some reason, you cannot simply subtract 90 from 368. 36860 equals 308. Then you subtract...

As we’ve noted before, when proponents of the Obama Administration’s Common Core education reforms try to make the case for the program, they often end up giving material to its opponents. Case in point: the Center for American Progress (CAP), in a recently released report on The Cognitive Science Behind the Common Core, attempted to show how much easier Common Core math is than traditional means of mathematical problemsolving: “Elizabeth is at the grocery store buying fruit for the week. She wants to purchase $7.60 worth of apples with a $20.00 bill. How much change should the cashier return to...

The Pioneer Institute, a Massachusettsbased think tank, released a new study, “The Revenge of K12: How Common Core and the New SAT Lower College Standards in the U.S.” to help parents, teachers, and policymakers understand the problems with the Common Core State Standards. Authors Robert Phelps and Common Core Validation Committee member R. James Milgram go indepth on the background of the Common Core standards and the qualifications (or lack thereof) of the writers of the standards. Milgram, an emeritus professor of mathematics at Stanford University, was one of five members of the validation committee who refused to sign onto...

I home school a young girl. In years past, we have gone to the local air show and done such things as measure the tops and bottom of wings and rotos and figure the ratio or difference between the area of the top of the wing versus the bottom and estimated which wings had more lift than others. We measure how much area the wheels occupied on the ground and consulted with the crew chief what the tire pressure was and calculated the weight of the plane. In years past we were able to see F18s form a vapor cone...

A simple addition problem seems to become a little more complicated under Common Core. That is made very clear in a new “Homework Helper” segment that recently aired on WGRZTV in Buffalo, New York. In the new educational segments, local teachers attempt to help confused parents better understand their children’s Common Core homework. In the introductory segment, a math teacher takes nearly an entire minute explaining why 9 plus 6 equals 15. “Our young learners might not be all together comfortable thinking about what 9 plus 6 is. They are quite comfortable thinking about their friend 10,” the teacher says...

Girls in New York City outperformed boys on the state's standardized math tests this year, widening the gap between the genders when it comes to math, new statistics show. More than 35 percent of the city's thirdthrougheighthgrade girls passed the state math test, up from 30 percent last year which was the first year of the harder tests aligned to federal Common Core standards. For boys, 33.4 percent passed this year's test, up from last year's 29.3 percent. It's too soon to know why girls' math scores are rising faster than boys', but some experts wonder if all of the...
