A Maths Fairy Tale for Grade 2

May 12, 2016

A Maths FAiry Tale Mathspig

Once upon a time, Grade 2 students did very boring work in maths. And they had to do lots of tests too.

Exam-question-trending-small_trans++qeu1EEj63qgC2KauuzlUjPS5plK0DADLTnlqUSkScwo

Sometimes evil witches wrote the test questions. These Year 2 (Grade 2) questions were very, very scary. Here is one of those very scary questions. It was so scary lots of people turned into angry birds when they saw this question. The angry birds tweeted that this question is ” too hard’. Tweet! Tweet! (The Telegraph , UK, 9 May, 2016)

A very wise old Mathspig worked out the answer.

X -19 +17 = 63

                X = 65

Mmmmm, this is a scary question for Grade 2. 

Many Grade 2 teachers are Wonderful Maths Wizards. They make maths magical and fun everyday. Students must sharpen their pencils and put on their wizards thinking hats to practise their maths. But maths can be magical and fun too. So here is:

A MATHS FAIRY STORY

A Wonderful Maths Wizard teacher can read the story out loud and the little Grade 2 Maths Wizards can write down their answers.

The absolute delight of Spurious Correlations is its craziness. Tyler Vigen is studying law at Harvard Law School, but he puts together the most ridiculous data you can imagine to show the correlation between eg. Per capita cheese consumption AND the number of people who died by getting tangled in their bed sheets, people who drowned after falling out of a fishing boat AND the marriage ration Kentucky. Of course, what Tyler is demonstrating is the basic maths principle, mathspiggies, that correlation is not causation. Here is one of his fabulous graphs:

 2. HeaderMath with Bad Drawings is run by Ben Orlin. He describes himself as ‘a math maths teacher in Birmingham, England. Before that, I taught in Oakland, California. I’ve taught (or am currently teaching!) every level of mathematics from ages 12 to 18.’

Not only is Ben’s humorous and fascinating take on maths interesting, his philosophy of life is worth a read too. e.g. We are all simultaneously experts and beginners, flaunting our talents while trying to cover our shortcomings the way an animal hides a wound.’

Here are two delightful examples of his maths with bad drawings:

Mathspig has written about the fabulous What if? blog before.

Randall Munroe is a pro web cartoonist, maths nut and maths guru who answers crazy hypothetical questions using maths. His home website is xkcd.

His TED lecture is here.

Randall offers this warning to his KXCD blog: this comic occasionally contains strong language (which may be unsuitable for children), unusual humor (which may be unsuitable for adults), and advanced mathematics (which may be unsuitable for liberal-arts majors). Of course, this makes his blog even more interesting. Maths, profanity and silly humour. Bring it on.

How What if? blog asks and answers interesting questions:

What would happen if I dug straight down, at a speed of 1 foot per second? What would kill me first?

Could a bird deliver a standard 20″ New York-style cheese pizza in a box? And if so, what kind of bird would it take?

Here is one example:

The joy of Yan’s One Minute Math blog is his eclectic collection of topics from . Kow-Cheong Yan is a Singapore-based teacher, math consultant, math blogger and maths book author (Grade 1- 6).

4a

The Lighter Side of Innumeracy gives an insight into maths incompetence and superstition in Singapore. It shows that charlatans can still prey on the innumerate. And Yan’s critique of Drill-and-Kill texts promoted in Singapore is refreshing in an age where politicians are forever calling for Back-to-basics teaching methods for maths.

4b

 But my favourite post on Yan’s blog is;

Mathematical Fiction is not optional. The number of novels using maths as a theme is inspiring especially with Yan adding a comment like this:

If you’re looking for math, women, sex, and back-stabbing, The Wild Numbers (Philibert Schogt) is a math melodrama unlikely to disappoint.

Could this be our new Maths Rock Star?

April 18, 2016

Could this be our new Maths Rock Star?

So Canada has a Prime Minister who not only understands Quantum Computers, he is really excited by the possibilities. And look at the blackboard behind him mathspiggies. That’s BIG TIME maths.

Grant Imahara (below), an engineering graduate, star of the TV show Myth Busters and more or less a Maths Rock Star himself, claims that bringing back esteem and awe for scientists and scientific studies will boost student interest in science and maths.

 GrantImahara350x350

“We need rock stars. In the 60s astronauts were rock stars … Everyone wanted to be an astronaut” said Imahara.

(Behind America’s Decline in Math, Science and Technology, USNEWS, 13 Nov 2013)

Justin Trudeau may just fit the bill. Justin is 44 years old. He first studied English Literature, graduating with a BA. After completing his BEd he worked as a teacher in Vancouver, British Columbia.

…………………………………………………………

Screen shot 2016-04-18 at 1.15.16 PM

Here is Justin in front of the blackboard. Look at the blackboard content.

It’s Middle School Maths!!!

Contrary to the general belief that Bachelor of Arts students don’t get maths, Justin went back to university and studied engineering. Then he tackled a Master’s Degree in Environmental Geography. He used his public profile to advocate for various causes and acted in the 2007 TV miniseries The Great War. He was elected to the House of Commons in 2008 and won the elections as leader of the Liberal Party in 2015, becoming Canada’s second youngest Prime Minister ever.

So Justin Trudeau really puts the GLAM in GEEK. He is a well-read actor, environmentalist, maths-geek Prime Minister. And a boxer too. We could do with a few more poiticians like him!!!

Then, maybe, all elections could be settled like this in the future!! Ha!

I particularly loved the post about Gabriel’s Horn:

3a Creative Maths

And pictures of Gabriel’s horn made out of paper cones. Gabriel’s horn is the surface obtained by revolving the curve y = 1/x for x> or = 1/2 about the -axis. Mathematics professors ‘wow’ introductory calculus students by sharing its paradoxical properties: it has finite volume, but infinite surface area. As they say, “you can fill it with paint, but you can’t paint it.”

 

The Golden Arches get a working over as well. Are they based on a parabola, Catenary (strung up chain hanging under it’s own weight) or other. It turns out it is other … the Golden Arches fit an ellipse.

4. Creative blog Mathspig

Visualising Math is a terrific Tumblr feed run by Monica Anuforo and Casey M. both college maths students from Minnesota, USA. I think Monic’a comments on the blog tell us all how important it is to engage Middle School students.

 

Monica Anuforo: Hello! I’m an 19 year old Nigerian-American female. Obviously, I’m a fan of mathematics. I was one of those people who were lucky enough to find out that MATH IS AWESOME as early as middle school as opposed to later in life.

 

4a Creative maths

 

The Tumblr feed is a fabulous collection of mathematical images including fractals, gifs and jokes. Some of these images (See below) could be drawn, coloured or constructed by Middle School students so they too can discover that maths is awesome!!!

Math for Lovers is an anonymous Tumblr feed run by Kcmr. It is an eclectic collection of maths art, gifs and jokes. While it hasn’t been updated for awhile the images are still worth exploring. Here are just two:

5a Creative Faig Ahmed

Faig Ahmed is an internationally recognized artist from Baku, Azerbaijan, who represented Azerbaijan at the Venice Biennale in 2007. He is well known for his conceptual works that utilize traditional decorative craft and the visual language of carpets into contemporary sculptural works of art.

5c Creative Cut and paste novel wall art

You have to love a maths blog that announces:

This is why geometry is important kids. It can blow your mind.

This is a brilliant clip of Klemens Torggler’s kinetic art door based on rotating squares. The special invention makes it possible to move the object sideways without the use of tracks.

Math is Beautiful,a maths tumblr stream, is oldish and seriously mathsy but some of the stunning visual images and interesting gifs would intrigue Middle school students. e.g. The image below is a screen grab of a circle of dots that rolls around the circumference inside a bigger circle …. but … but .. but … the gif shows that the dots actually only move along the diameters marked. Fas-kin-ating!

When Pi Day is sooooo Embarrassing

March 10, 2016

Mathspig Pi Day

In Australia we don’t get too carried away with 14 March aka Pi Day aka 3.14.16 because, unlike Americans,  we do not write the date as 3/14/16. We prefer 14/3/16.

No problem.

Meanwhile Mathspig called her upcoming talk for the International Congress of Mathematical Education 2016 in Hamburg:

How many m&ms would kill a 14-year-old? Making middle-school maths real, relevant, deadly serious and π-in-your-face funny!

Then  odd emails arrived relabelling my talk  ‘…….. p-in-your-face funny!’

I thought it was a typo. Not so! The Germans, the Dutch and other European countries do not call π ‘Pi’, they call it ‘P’ or ‘Pee’ because ‘i’ is pronounced ‘ee’, for instance, in German. So I had called my great international maths talk Pee-in-your-face funny! And the German organising committee seemed happy enough with the title.

To be diplomatic and to avoid the attracting the wrong type of audience I’ve retitled my talk:

How many m&ms would kill a 14-year-old? Making middle-school maths real, relevant, deadly serious and ha^2 funny!

So Happy π Day English speakers and now, for a laugh, look at some of our Pi or Pee jokes through the eyes of, say, a German.

Mathspig Happy Pi Day Europe

Pi Day 2

That’s because of the beer.

Pi-Day

One whole day dedicated to pi.

It’s epic!

Pi Day 3

Mathematicians in love .., awwww!

So cute or they’re pissed.

………………………………………..

Pi Day 4

OK. ‘I 8 sum pi’ but adding the ‘delicous’ makes this weird for a German. D’Oh!

pi Day 5

Very expensive bottle of pi.

Pi day 6

Mmmm! Pecan pi.

Pi Day 8

Rabbit Pi must be a problem.

Pi Day 10

Dessert wine, maybe?

Pi Day 9

That’s, like, every day after a night out on the ‘piss’ as we so delicately call it in Australia.

pi Day 11

You too can have tasty pi. I don’t know how and frankly, I don’t want to know.

Mathspig has gone, like, totally Cubist this month. You too can turn any portrait of yourself into a Cubist Master piece (See Mathspig portrait above), here.

Mathspigs maths friends, Lyn and Erwin, who I met at the 13e Salon Culture & Jeux Mathematique, Paris, have sent me a reminder about their amazing Cryptocube construction kit (Mathspig is twirling one above) . This is not for the faint hearted. It’s a Big Maths challenge, but well worth the investment especially for schools. You can learn more about the Zometool Cryptocube construction kit here.
