So today my son had the age old doubling question in his math book.

There are many ways to word it, from rice bowls to pennies, to gold pieces, but in general everyone should know the answer.

one version
the gist is you can have one penny the first day, then it doubles each day, 2 the second, 4 the third and so on. Or a large flat fee. Which is better?

I know the theory, but I am not a fan of numbers, so I generally let excel do the math.

But today doing the math, "How much will you make on day 30?" was the question so some number crunching was in order (he can do the math himself but I have to check it)

After discovering day 30's amount, he wanted to know what day you would get over 1 billion, so off he went to crunch numbers. Wasn't done with his other work, but it is prolly better to let him do math when he wants, than to force him to do work in any particular order.

here is a one grain rice
doubling with a moral.

On a related note I keep finding that boy reading when he could be working..still rather hard to make him stop reading for little things.

What would the world say if I told EL (7 months old) she had to learn to talk right this minute, no matter how interested she was in walking?
