Mathspig outdoor play quote

A growing body of research shows us that outdoor play leads to better physical and mental health, has positive effects on cognitive function and learning, and reduces the incidence of behavioural problems.” Maria Zotti, Nature Play, SA.

Peter Dunstan, Principal Kilkenny PS, SA, writes in SAPPA magazine, Primary Focus, that outdoor play fosters “wonderment, independence and freedom” as well as “social skills, imagination, creativity and problem solving”.

Inspired by SAPPA and NaturePlay,  Mathspig has produced her own outdoorsy maths list:

Happy Pi Day! Ooops! Not you Germany!

March 14, 2019

There is a fab article on the History of calculating pi in the New York Times today.

Now to THE FUNNY SIDE OF PI DAY

In Australia we don’t get too carried away with 14 March aka Pi Day aka 3.14.19 because, unlike Americans,  we do not write the date as 3/14/19. We prefer 14/3/19.

No problem.

Meanwhile Mathspig called her  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.

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.

The Terrifying Math of Running from a Bear … USA Units

July 17, 2017

USA UNITS below. METRIC UNITS here.

BEAR STATISTICS

Grizzly Bear

Weight:  550 lb        

Height:  8’ 2”   

Top Speed: 35 mph  =   51 ft/s    

Brown Bear

Weight:  1,500 lb       

Height:  8’ 2”              

Top Speed: 22 mph  =  32 ft/s     

Comparing these speeds to the fastest man on earth, Usain Bolt:

Usain Bolt:

Top speed: 27 mph  =   40 ft/s     

Bears are not dangerous:

………………………………………………………………………


In fact, more Americans die each year from choking on their own vomit than are killed by bears.

More death stats here

Nevertheless, bears are very fast. So you can see why Park Rangers offer the following advice:

More information at Mountain Nature.

The reason for waiting until the bear is 15 ft away is to make sure the spray doesn’t disperse in the air. If the Pepper Spray is too spread out it will not stop the bear.

Ref: Dog helps save hikers after grizzly chases them for 20 minutes.

mathspig-australia-vs-germany

I started my maths workshop in Hamburg by stirring up some friendly rivalry.  And what better way to do this than by using statistics.

Which is the biggest country?

Australia is 21.5 times the area of Germany. So I counted off 22 workshop participants and pointed to one saying ‘Your’re Germany! Ha!’ Here’s another way to compare areas:

Which country has the largest population?

Germany has 3.5 times the population of Australia.

But the really interesting questions are:

Who drinks more beer?

Who eats more meat?

Here are the answers to these and other interesting questions from the introduction to my workshop with apologies to Brisbane and Perth:

Here are some amazing ways to make middle school maths AMAZING:

1. Defronting the Maths Classroom

Mathspig gravity plane

We all know about gravity. We worry about gravity.

GRAVITY CHALLENGE

If someone holds a pen in your hand like the gif below, then drops it,

I bet, if you keep your hand in the one position, that you can’t grab it!!!!

The maths is soooo beautiful.

www.GIFCreator.me_OLwVWU

All objects and bodies drop at the same rate of acceleration, g = 9.8 m/sec2

d = distance travelled by falling object (m)

t = time taken (sec)

pen drop formula 1

pen drop formula 2

You can test your reaction time on THE REACTION TIME CLOCK HERE.
