quorn3000on Teaching Square Roots to a Five Year Old

I've been thinking how to explain to my 8 and 6 year olds that the square root of a prime number is irrational.

I've been over primes lots of times. I've talked about decimal fractions, repeating decimals, and the possibility of there being numbers which are non-repeating. I know the proof for the square root of 2 being irrational. It's just tying it all together.

quorn3000on 10 Great Blogs for a Developer's RSS Feed

Why 10 though?

If there's one more that is as good as the other 10 then I'm happy with 11.

If there're one or two to make it a round number, I don't want to know about them.

The poster is taking the role of curator. Having 10 makes me think they haven't been disciplined, an important activity in curation.
