Pediatric gastroenterologist David Milov told the magazine Scientific American that he can say “with complete certainty” that gum does not stay in you for seven years.

You will find more than you ever wanted to know about the structure of chewing gum (It’s a rubber-based substance though now mostly synthetic) and it’s digestion at the above website and here.

Sometimes, it feels like chewing gum will stay on your shoe for 7 years!!

Trick 10: Math Mentalist Devises Foolproof Gambling System

November 30, 2012





Math Mentalist Devises Foolproof Gambling System

Requirements: Smart board/Data Projector

or Chalk & Talk

This is the most awesome way to introduce probability.

Mentalist Derren Brown devises a foolproof gambling system. He sends a girl , Kadisha, the number of a winning horse in race to be run the next day. It wins. He sends her the winning horse and race number 4 more times. She ends up with winnings close to £ 1000 before the final race. Derren convinces her to borrow money for the last bet. She does. She places £4,000 on a horse. Did it win?????

Watch Part 5 of The System



If you are not convinced Derren Brown can come up with a foolproof system for horse race tipping, let me explain The System. He took 7,776 e-mail addresses, divided them into 6 equal groups and sent each group a different number for a horse in a 6 horse race to be run the next day. Naturally, one group of 1296 had been given the winning horse number.  This group was divided into 6 again and given the number of the ‘winning’ in a six horse race the next day and so on.

Race 1: 7776

Race 2: 1296

Race 3: 216

Race 4: 36

Race 5: 6

Out of 7776 punters, only one punter was given in advance five horse race winners in a row. Was it Kadisha. You will have to watch the Youtube above.

You can watch THE SYSTEM in full here. It takes 47 mins.


1. Bart Simpson Moment

August 3, 2011








Kids who finish the classroom exercise can write lines Bart Simpson Style on the blackboard.


Here are some possibilities:

A scalene triangle does not have a skin disease.

The Bermuda Triangle did not swallow my maths homework.

Al-gebra is not a terrorist organisation.

I am not studying maths to become a maths murderer.

A Pie Chart is not a menu.


For senior students:

Trigonometry does not involve sin, secs and fake tan.

√666 is not the root of all evil.

An asymptote is not a small, loud farting sound.

A binomial function has nothing to do with sexuality.

A permutation is not a mutant hair treatment.

For inspiration and to use the Bart Chalkboard generator:


25. Maths the Musical!

August 3, 2011







To promote maths students are to busk outside the staffroom or the Principals Office. They will have to work up their act in class. You can rewrite anentire musical in maths terms. Here is one song.

Hit it mathspigs.


Based on the chorus of Greased Lightin’ by John Travolta

Go, Factorisin’

You’re burnin’ up the problem, yeah!

Factorisin’, go Factorisin’

Go Factorisin’

You’re coasting through the algebra

Factorisin’, go Factorisin’

You are supreme

The teachers scream

For factorisin’

Go go go go go go go go


10 Reasons Why Maths Teachers Rock!!!!

January 4, 2011

Science Teachers can be a little creepy.

Music Teachers can get carried away.

The new foreign language teacher can be too friendly.

PE teachers expect you to enthusiastically embrace the challenge of  freezing your ass off outdoors.

Domestic Science teachers teach too many useless things like how to boil an egg or shrink a child.

Librarians get really upset when you don’t return books.

Art teachers can go too post-modern.

English teachers nag you to read books that are, get this, already out on DVD.

Drama teachers can get too carried away with the performance concept.

Some teachers really do know how to make you do your homework!

But maths teachers …

Oh YEAH Maths Teachers

we are cool, babe!

… like totally co^2l!


But Baby, my Feets too Big!!!!!

September 22, 2009

Confused_tnsThose Hippie Statisticians at The Australian Bureau of Statistics (ABS)  are Navel Gazing Again!!!! . Here are the statistics for the height of students belly buttons above the ground for Year 4 – 12 students. ABS  #mce_temp_url#

policeman_stop_tns Stop!!! WARNING!!!

Before we do any maths with students height mathspigs, be warned. Students can be teased or embarrassed by their height. Mathspig has always argued that a lampost is tall but does not have much of a personality. And a bee is very small but you’d be crazy to tease one. Nevertheless we will use celebrity heights and average student heights instead. 

Here we go!!!!!




 Look at the data. It is useless. THIS IS THE POINT. You have to make sense of data not just sprout numbers. Foot sizes actually shrink!!!! There is insufficient information. The ABS random sample size used was too small. So baby your feet might be too big… but we can’t tell from this data.









 Q2: Does the ‘average’ Aussie student have divine proportions?Da_Vinci_Vitruve_Luc_Viatour

 The Vitruvian Man is a world-renowned drawing created by Leonardo da Vinci around the year 1487. This sketch supposedly represents the perfect proportions in man. Measure Height and Belly Button Height of Vertruvian man. Divide his Belly Button Height by his full height.

We will call this the DIVINE FRACTION. 

How do Aussie Students compare? You have the data needed to calculate the DIVINE FRACTION for each year level.



Q3: How do the average heights of our  students  compare to students in other countries?

If we could took a very, very large number of student heights they would produce the graph below. It is a NORMAL DISTRIBUTION or A BELL CURVE. The curve below is for young adults in the USA. We do not know the actual number of students for each height.  

ADVANCED MATHSPIGS; You will find more data, a cute bar graph using students  and some interesting bimodal graphs (combining the Bell Curves for Female and Male heights) @#mce_temp_url#

How do Aussies compare? See the graphs below. We do not know how many students are involved. We can only say  our average Year 12 student is taller than the majority of their students!!! Ha! HA! If, that is, the data is reliable and the foot sizes suggest maybe NOT.

 Q 4:  How does the average height of  Aussie students for each Year level compare with celebrities? 

The pics and some stats come from The Sunday Age ( Coming Up Short 13th Sept 2009) . Here are some celebrity heights:

Mathspigs Unite!!!

June 4, 2009

Mathspig has just found a fabulous maths blog run by Victorian maths teacher, Jeff Trevaskis, who is rumored to teach up Mooroopna way.mooroopna map Correction

Jeff’s blog, called Webmaths is full of interesting challenges, real classroom maths ideas and other fun stuff. #mce_temp_url#  




 Meanwhile Jeff has thrown down the gauntlet challenging all mathspigs everywhere. 

 For no greater love has any mathspig than to don his tutu and appear in public to promote mathematics.
