Creativity or Stupidity?


This week, I saw this attached (grade one?) test item or math meme on Facebook, which was initially posted by “The Language Nerds” group.

Based on the multiple comments to this ill-posed math question, it’s amusing, yet also disturbing, to read that most responders are praising the student for his “creative” answer, or criticizing the “uncreative” teacher for penalizing the poor child.

In this postmodern or polarized world we’re living in, you’d think that maybe only someone who’s a “very stable genius” would rationalize or argue that the student’s response qualifies as one of the equally valid answers. And if the biased teacher insisted on marking the creative child wrong, the parents might consider suing him or her for giving their son an undeserved zero.


Creative or Uncreative Comments

Below are some netizens’ replies to the math question from “Maths Jokes Daily,” which range from the hilarious to the ridiculous to the preposterous.

I think because the circles weren't closed properly 🤔

honestly think its possible for most people to understand what you are supposed to do here, so I would definetely argue that this is not a badly formed question :)

Were the correct answers 1.39, 2.17 and 3.96 ?

He got it wrong because he marked 3 numbers, and the question only asked for one, so the right answer is 15

He provided 3 right answers. He identified the smallest number in each row disregarding the periods and commas. LOL !

He circled 3 numbers. Number 1 is the smallest number and therefore should have only selected the 1 single number.

Also, why did the teacher put 3 lowercase "alpha" symbols?🤣

it’s evident smallest number and not smallest numberS so he should have circled only 1

Because he only circles 1 but not 1.39 Same with others

The fault lies entirely with the fool that numbered the questions with Roman Numerals and then used 1, 2, 3 instead of a, b, c

That kid is already smarter than the teacher.

Thats at least .5 for thinking outside the box

? ! ? ! ? ! ? ! ? ! ? ! ? ! ? ! ? ! ? ! ? ! ? ! ? ! ? ! ? ! ? ! ? ! ? ! ? ! ? ! ? ! ? ! ? ! ? ! ? ! ? ! 


Would you side with the teacher or the student? How would you respond to the “wrong” answer to this ill-posed or improperly posed question?

Creatively or uncritically yours

Seven Irreverent Definitions of Singapore Math

Since I started christening mathematical words on Urban Dictionary, as someone who makes a living evangelizing the gospel of Singapore Math, it’s too tempting not to attempt defining the love-or-hate term, depending on your personal experience with the alien, hybrid math curriculum. Indeed, your geography or maturity would most likely determine your position or reaction vis-à-vis Singapore Math—for a number of you, not only you love Singapore Math, but Singapore Math loves you, too!

Since last December, I discovered that out of the hundreds-odd math terms or phrases I had contributed to Urban Dictionary—the "anti-Wikipedia"—under different pseudonyms, one “terrorist stalker” has been serially and wickedly downvoting a number of them on a daily basis to the point that the online dictionary had to temporarily suspend and eventually remove the most downvoted entries to prevent further digital abuse or digital persecution—two of those deleted definitions involve Singapore Math.

The Fear Factor in Singapore Math Education

If math teachers, tutors, writers, and editors were given the assurance that they wouldn't be punished, fined, jailed, or even caned for speaking up and speaking out on the good, the bad, and the ugly of Singapore math education, it's inconceivable why Singapore couldn't potentially become a global mathematical hub of choice for those born with the mathematical gene (let’s pretend that there’s such a thing) and a sense of humor or irreverence.

As a proof that we in Singapore aren’t the boring, exam-smart math educators that some outside the island-state would like to portray us, below are seven irreverent or light-hearted definitions on Singapore Math, which were approved and published on Urban Dictionary, the World's No. 1 online dictionary.
















Could you figure out which two of the seven definitions were "censored" or deleted? At one point, I thought maybe there is a vigilante math squad, a subset of the small army of moral and political policemen and women, recruited by the Singapore authorities to monitor any citizens or residents who try to publish any mathematical thing, which speaks ill of the government, the police, the army, and the judiciary. 

Who knows that these e-censors might be on the lookout to report any "mathematical black sheep" to the authorities, who might then threaten and sue them, if they refuse to take down any content or comment that allegedly promotes the dark side of math or math education in Singapore?


Singapore Math with a New Twist

May I encourage you to redefine “Singapore Math” based on your personal experience and interaction with fellow math educators, students, parents, and caregivers (or maids-turned-tutors). Indeed, Singapore Math has many faces, and your unique perception and definition of it would allow us to peek at a hitherto unseen (sexier or darker) side of it. It's never too late to share your definition (or frustration) with fellow math educators.

In Singapore Math, we trust!

Gross Singapore Math



© S. Mockus, & T. Millard, (2010)

Estimation (or guesstimation as it is more commonly known in the U.S.) is a creative mathematical activity that is seldom given enough curriculum attention and time in Singapore. For the lay public, and probably for a disturbingly large proportion of local math teachers, tutors, and parents, estimation is often confused with approximation (or rounding off numbers).

Like swimming, cycling, and driving, estimating ought to be a life skill that is indispensable for all responsible citizens aiming to be numerate in our quantitative world of bloated data.

A PSLE Estimation Routine

In this year Singapore's PSLE (grade 6) math paper, a routine guesstimation MCQ question has irked some parents, who "blamed" the Ministry of Education for posing an "unfair" question.


Ghostly Math from @MathPlus

How to Fermi-ize

Current Singapore math textbooks are often too Puritan, not to say, boring, to contain fertile exercises that could hone students' estimation skills. A dose of humor, without insulting or shocking the readers, will go some way in nurturing some Fermi disciples. Let's look at eleven non-drill-and-kill guesstimation questions, which could be posed to above-average math students bored by school math.

0. Zero Toilet Paper 

If all the toilet paper used in Singapore in an entire year were rolled out, how far would it stretch?


1. The Trillionth Heartbeat

Assuming an average human heart of 72 beats per minute, estimate that most folks would breathe their last breath around their billionth heartbeat, or by their near-666 weeks of life on this side of eternity.

2. Pools of Eyeballs

About how many Olympic-sized swimming pools would all the world's human eyeballs fill?

3. Death Nailed by Tobacco Sticks

© Chua Sin Yew

A medical association claims that a cigarette smoker shortens the length of his life by 9 minutes for each cigarette smoked. A student smokes three-quarters of a pack of 20 cigarettes every day for 30 years. Excluding leap years, by how many months or years has this student cut short his life to?

4. To Pee or Not to Pee

How much urine is in a typical public swimming pool? Or, how much pee in a pool would kill you?

5. Length of Intestine

If you were to pull your small intestine out and laid it in a straight line, how long would that be? Is it shorter than the distance from Earth to Moon?

6. A Nation of Vampires—Human Blood Aplenty

If you were to take all the human blood from all the living people in Singapore and pour it into the Singapore Indoor Stadium, how deep would it be?

© Mark Parisi

7. Zoo Poo

Estimate how much zoo poo is collected every week at the Singapore Zoological Gardens. How much of it could be used as fertilizers?

8. The Host with the Most

How many (unfriendly and not-s0-friendly) bacteria are living on and inside you right now?

9. Cash in on the Trash

Show that, on average, every square mile of sea on the planet contains 46,000 pieces of rubbish. How much cash could be generated annually by an entrepreneur involved in the trash business? [1 mile is about 8/5 kilometers.]

10. Green Pollution

© Sidney Harris
Thanks to Indonesia's mostly incompetent politicians and corrupt businessmen, its neighbors Malaysia, Singapore, and Thailand, have unhealthily been affected by the annual haze visiting them, as a result of illegal forest burning by local farmers to save costs for their bosses.

Guesstimate the number of people inside and outside Indonesia, who have been affected in the last two decades from this man-made pollution. How many natives, Mohammedans, and "infidels" will die prematurely because of near-zero political will from oft-corrupt Indonesian politicians?


Estimation Skills via Gross, Illegal, or Murderous Math

Be it via "Gross Math," "Murderous Math," or "Illicit Math," creative or fertile questions on the "shit," "death," or "illegal" business, could be posed to enhance students' guesstimating skills.

Indeed, gross Singapore math could serve as a catalyst to imparting real-life estimation skills to students, and to reducing more complaints from kiasu Singapore parents, whose children will be sitting for the PSLE oft-dreaded math paper in coming years.

Selected Answers
2. About 73 swimming pools.
5. About 18 miles long.
8. About 2,000,000,000,000,000 bacteria.

The Ig Nobel Prizes in Mathematics

We don't have a Nobel Prize in Mathematics, and a number of hypotheses have been put forward to rationalize why Mr. Alfred Nobel didn't see fit to award such a coveted prize to the mathematical fraternity.

The closest (or an equivalent) to a Nobel Prize in Mathematics is the Fields Medal, officially known as the International Medal for Outstanding Discoveries in Mathematics, which is granted every four years to between two and four mathematicians for outstanding or groundbreaking research. 

Traditionally given to mathematicians under the age of 40, Fields medalists receive an honorable Can$15,000, an amount probably sufficient enough to defray the cost of their airfare and accommodation should they decide not to channel their winnings to some charitable organization.

Ig(noble) Nobel Prize in Mathematics 

For the majority of mathematicians who can't be nominated for a Fields medal, because they're not born with the "mathematical gene," there's still an infinitesimal hope that some may be awarded an Ig Nobel in Mathematics.

The Ig Nobel Prizes are an American parody of the Nobel Prizes and are given each year in early October for ten unusual achievements in scientific research. The prizes are to "honor achievements that first make people laugh, and then make them think." 

These highly-coveted prizes are awarded in many categories, including the Nobel Prize categories of physics, chemistry, physiology/medicine, literature, and peace, but also other categories such as public health, engineering, biology, and interdisciplinary research.

Organized by the scientific humor magazine Annals of Improbable Research (AIR), these awards are presented by a group that includes Nobel Laureates at a ceremony at Harvard University's Sanders Theater, and they are followed by a set of public lectures by the winners at MIT.

Ig Nobel Laureates

Let's look at some past Ig Nobel winners in Mathematics, Probability, or Statistics.  

The Ups and Downs of Cows
2013 Probability Prize
Bert Tolkamp, Marie Haskell, Fritha Langford, David Roberts, and Colin Morgan, from the UK, for making two related discoveries:
1. The longer a cow has been lying down, the more likely that cow will soon stand up.
2. Once a cow stands up, you can't easily predict how soon that cow will lie down again.

The End of the World
2011 Mathematics Prize 
Dorothy Martin of the USA (who predicted the world would end in 1954), Pat Robertson of the USA (who predicted the world would end in 1982), Elizabeth Clare Prophet of the USA (who predicted the world would end in 1990), Lee Jang Rim of Korea (who predicted the world would end in 1992), Credonia Mwerinde of Uganda (who predicted the world would end in 1999), and Harold Camping of the USA (who predicted the world would end on September 6, 1994 and later predicted that the world will end on October 21, 2011), for teaching the world to be careful when making mathematical assumptions and calculations.

The Hundred Trillion Dollar Book 
2009 Mathematics Prize
Gideon Gono, the governor of Zimbabwe's Reserve Bank until 2013, for giving people a simple, everyday way to cope with a wide range of numbers—from the very small to the very big—by having his bank print bank notes with denominations ranging from one cent ($.01) to one hundred trillion dollars ($100,000,000,000,000).

The Number of Shots
2006 Mathematics Prize 
Nic Svenson and Piers Barnes of the Australian Commonwealth Scientific and Research Organization, for calculating the number of photographs you must take to (almost) ensure that nobody in a group photo will have their eyes closed.

Elephantine Surface Area
2002 Mathematics Prize
K.P. Streekumar and the late G. Nirmalan of Kerala Agricultural University, India, for their analytical report, "Estimation of the Total Surface Area in Indian Elephants."  


No winners from 1999 to 2001.

Private Dimensions
1998 Statistics Prize
Jerald Bain of Mt. Sinai Hospital in Toronto, and Kerry Siminoski of the University of Alberta, for their carefully measured report, "The Relationship Among Height, Penile Length, and Foot Size."

No winners from 1995 to 1997.

Who Are Going to Hell?
1994 Mathematics Prize
The Southern Baptist Church of Alabama, mathematical measurers of morality, for their county-by-county estimate of how many Alabama citizens will go to Hell if they don't repent.

Mikhail Gorbachev, the Antichrist
1993 Mathematics Prize
Robert Faid of Greenville, South Carolina, far-sighted and faithful seer of statistics, for calculating the exact odds (710,609,175,188,282,000 to 1) that Mikhail Gorbachev is the Antichrist.

Note: In 1990 Mikhail Gorbachev was awarded the Nobel Peace Prize.

No winners in 1991 and 1992.

If you think that academic papers are darn boring, The Best of Annals of Improbable Research would dismiss that!
