500,000 Hog Hits

April 27, 2013

Mathspig is sooooooo excited

about reaching:

5 etc hits

To celebrate 500,000 or 5×105 hog hits

 and to continue showing mathspiggies everywhere

that maths is fun

and relevant to all

Mathspig presents

The MATHEMATICAL

CABINET OF

500,000

CURIOSITIES!!!

………………………………………

1

………………………………………………………

If you took a sample of

500,000 US teens

how many DO YOU THINK fall

asleep at school

at least once a week?

asleep

You will find amazing US teen stas here:

28% report falling asleep once a week

 500,000 x 28/100

= 140,000

Snoring to the left of you. Snoring to the right of you. You are not alone.

What volume of coke is there in 500,000 cans?

coke shower

Coke can vol = 355 ml = 12 fl oz

500,000 x 355 = 177,500,000 ml

= 177, 500 l = 177.5 m3

……………………………………………

An average bath uses 150 litres water per bath.

How many bathtubs would 500,000 cans of coke fill?

177,500/150

= 1,183 baths in coke!!!

Hey mathpiggies, wanna bubble bath? You’d be tickled pink.

In a crowd of 500,000 how many people

would have their birthday

on the same day as yours?

bd cake

There are 365 days in the year so the probability of anyone having their birthday on the same day as you (ignoring leap years) is:

1 in 365 or 1/365.

 

In a crowd of 500,000 the number of people who have a birthday on the same day as you is most likely:

500,000 x 1/365 = 1,370

That’s a lot of birthday cake!!

………………………………………………

………………………………………………..

4   How heavy is $500,000 dollars?

 money bag

Australia:

$ Aus

Wt Aus $1 coin = 9.0 g

If the bank gave a bank robber $500,000 in $1 coins it would weigh:

500,000 x 9.0 = 4,500,000 g

= 4,500 kg = 4.5 tonne

………………………………………………

………………………………………………..

UK:

UK [pound coin

.

Wt UK £1 coin = 9.5 g

500,000 x 9.5 = 4,750,000 g

= 4,750 kg = 4.75 tonne

…………………………………………………..

…………………………………………….

USA:

$ usa

Wt US $1 coin = 8.1 g

500,000 x 8.1 = 4,050,000 g

= 4,050 kg = 4.05 tonne

You will find all you need to know about the size and weight of US coins and notes here.

$500,000 in $1 notes would only weigh

11 lb or 5 kg.

……………………………………………….

So, um, bank robbers do the maths!!!!!!!!!!!!!!!!!!

How far would you walk in 500,000 steps?

We’ll assume you take a big step of 1m.

step

So 500,000 m = 500 km.

A comfortable walking rate is 5 km/hr.

How long would it take you to walk 500 km without a break?

500/5 = 100 hrs.

………………………………………………

………………………………………………..

6 049_tns6 bugatti-veyron-super-sports-480

The Bugatti Veyron Super Sport  hits a maximum speed of 267 mph (429 km/h).

How long would it take the Bugatti travelling at top speed – not including refueling time – to clock up 500,000 km?

500,000 /429  = 1165.5 hr

= 48.5 days

The speed of an average sized commercial passenger plane ≈ 500 mph 0r 800 kph or

≈ twice the speed of the Bugatti.

So it would take a passenger plane approx 24 days to travel 500,000 km.

………………………………………………

………………………………………………..

7 A&E

How long would it take you to count to 500,000?

kid counting

Assuming you count at the rate of 1 per second the time it would take is 500,000 seconds.

500,000/ 60 = 8333 mins = 833/60 hrs

= 13.88 hrs or 13 hrs 53 mins

Come on! You could do that mathspiggies!!!!!

………………………………………………

8gloom

 In a group of 500,000 US teens how many are serious cave dwellers or, to be more accurate, how many spend less than 3 hrs a week outdoors?

It is an amazing 30.1%.

500,000 x 30.1/100

= 150, 500 creatures of the gloom.

Come on you teen gloomagogs get outdoors. You need the sun. You need the Vitamin D.

9m&ms

How many calories in 500,000 m&ms?

There are an amazing 400 million m&ms produced everyday in the US. One m&m weighs 0.7g.

And calories in 1 m&m =  3.4 cal

500,000 m&ms weigh:

500,000 x 0.7 = 350,000 g

= 350 kg

As 400 million or 8 x 500,000 m&ms are produced each day, that is 8 x350 kg or 2800 kg or 2.8 tonne.

Calories in 500,000 m&ms is:

500,000 x 3.4 = 1, 700, 000 Cal

m&m kid

As the average consumptionof chocolate in the US is 5.18 kg per year eating 500,000 m&ms would take:

ranking_of_consumption_chocolate_2007

350 kg/ 5.18 kg

= 67.6 years!!!!!!!!!!!!!!!!!!!!!!!!

You better get going!!!!!

10ablink

Blink rates vary but the average blink rate in a laboratory setting for a human is 10 blinks per minute.

How long would it take for you to blink 500,000 times?

500,000/10 = 50,000 minutes

= 50,000/60 hrs = 833.3 hrs

= 833.3/24 = 34.7 days

= 34 days 17 hrs 17 mins

But don’t think it or you’ll go blink crazy!!!!

1 Fabulous Mathematical Chairs

April 9, 2013

Maths-is-Awesome Activity

Fabulous Mathematical Chairs

Skill: Arithmetic, geometry, measurement

Level: Junior, Middle School

Here are two brilliant ways of using maths to create something awesome. Firstly, using fantubes, you can build a chair.

You would have to work out how many fantubes  you need. Measure up a standard armchair and then divide the width and depth by the diameter of the fantube.

Or you could just count the number of fantubes in this picture. More info here. Then – this is the PR bit – invite the School Principal into Maths Class to sit on the chair. Will your principal have faith? Or chicken out?

104.1 fantubes-double-ei--537x377

Secondly you could make this folding cardboard chair.

104.2 beeld_main-ponoko

104.3

More info here.

It would be fabulous if every student made a cardboard chair and then you went into the school yard for a lesson!!!

That would get attention.

To make it more fun, how about adding a cardboard teacher!!

If Martin Schilling could make these Conic Sections, so can any senior student. You will find Conic Section diagrams and equations here.

Could you do this mathspiggies?

Maths-is-Awesome Activity

Bring on the Bucky Balls

Skills: Geometry, polygons, measurement  …. and creativity.

Levels: Junior School & Middle School

In this activity students will create their own, preferably life-sized cardboard igloo. Igloo structures can be complicated or simple and in this project students must design and then build an igloo using a standard hexagon. Here are some inspiring designs.

Exif_JPEG_PICTURE

The first igloo was built using computer generated constructive geometry. It uses a basic – but distorted – hexagonal cardboard unit and was built by by the students of the Faculty of Architecture, University of Porto. You can see the construction method below. More info here.

99.2

The next cardboard igloo is based entirely on circles. It was designed by  students of ETH Zurich in Switzerland. More info here.

99.2 Cardboard Igloo

The following cardboard igloo based on triangles looks simple but has a very strong construction. More info here.

99.5 triangle igloo99.6 tirangle igloo construct

But the Granddaddy of the geometric or geodesic dome was Buckminster Fuller, who has been honoured by having a carbon-based nano-molecule named after him. They’re called Bucky Balls. If you look at the geodesic dome below you can see the HEXAGONAL PATTERN also visible int he Bucky Balls.

Maths-is-Awesome Activity

Cardboard Labyrinth

Skills: Graphing, modelling …. mostly generates inspiration

Levels: Any

98.1 Carlos-Teixeira-Layered-Cardboard-Labyrinth-Installation-2-537x358

Brazilian architect Carlos Teixeira created an incredible labyrinth made entirely from layered recycled cardboard for the 29th International Biennial in Sao Paulo.

More info here.

Labyrinths are mysterious. And mathspiggies, look at that lovely parabola. Making a labyrinth on this =scale may be beyond the resources of a maths class … but then again some imagination and some maths skills and voila:

98.3 thumb_4787_img-3329

In phase one of the project 240 students at Kingsford Primary School in Aberdeen used interconnecting materials to design and build a labyrinth inspired by the story of Icarus.
