the powerpoint gives one 'play'

it needs to be played against someone else

a billion

supposedly what a billion dollars looks like

we seem to have adopted the (U.S.) version of 10^9
this is sometimes called a milliard, or so I've read.




 a billion seconds is 31.7 years
a billion minutes ago, the Roman Empire was flourishing
a billion hours ago, humans were Stone Age (Middle Paleolithic to be precise)
a billion metres is around 3 times the distance from the Earth to the Moon

the population of India is over 1.2 billion
the population of China is over 1.3 billion
that of the World is around 7 billion.

a human genome (not too different to other genomes) carries 3 billion letters of DNA code

for trillions (apart from very large national debts) we have around 10 to 100 trillion cells in our body - but estimates vary

it's always seemed helpful that in India they use the lakh for 100, 000 and the crore for ten million (10, 000, 000)

maybe we don't have enough names for things

size of a million

1, 000, 000
Students can estimate answers, then calculate them.

1 million cm = 10 km, roughly 6.25 miles
1 million pence = £10, 000
1 million grains of salt = half a cup
1 miilion seconds = 11.57 days, less than two weeks
1 million burghers = 600 cows
1 million words is around 4000 pages of an average book
1 million cm^3 = 1 m^3 (a neat model for a million)

The Daily Mirror contains around 125, 000 words so a million words would be roughly 8 copies of this newspaper.

The Independent has around 130, 000 words (so 7.5 of these).

Man Utd attendance is around 76, 000. How many games to make a million?

Terry Pratchett's 'Johnny and the Bomb' (1996, with 272 pages) contains around 70, 500 words. How many readings of this to make a million words?

JK Rowling's 'Harry Potter and the Goblet of Fire' (2000, sales exceed 6.6 million and the book has 636 pages) has around 258, 600 words. How many readings of this to make a million words?

Stomach fluids have a million times as much hydrogen as water.

Molecules rotate at a million revolutions per second.

And the sheep?
There is a 1 in a million chance of a ewe having 5 lambs apparently.
