Another one is how the brain processes numbers. Get pupils to guess (in two separate halves, in their books)

1 – 1+2+3+4……..+19+20

2 – 20+19+18……..+2+1

No idea how to use this in class.

Oh, and another thing, some tests are 99% accurate, I mean medical. Given millions of people take some health tests, how many people will be told they have an illness but actually don’t. A scary amount is key, create here to Derren Brown and Dan Goldacre where I borrowed these ideas from.

Of course, if it had said stones, instead of pounds I might have stood a better chance… ;-)

I have to admit I do know a wee bit about American football, although if you were Welsh, football would probably be rugby and not soccer, and isn’t the point that feet should be largely involved in kicking, but what do I know about sport anyway.

Interesting link-in to the ideas of culture that were raised in the ‘pseudo-context’ post and comments, though, and I still like the idea of starting with a baby’s dimensions and working something out from there…
