# How to Build a Quadrillion.

We got those wooden magnetic numbers in Dollar Tree some time ago. I thought it would be nice to use them for a number line, and I “squeezed” the number line out of my daughter, but she was not really interested in it. She was a lot more interested in “building the infinity”. She learned about infinity from Missing Math book that I reviewed here. She would build a series of numbers and make me read it. I admit that when we got beyond trillions I told her that I need to look it up on the computer. She loves it when we do “research”. So now we both know that we have built a quadrillion. Anna also wanted to do “magic math”. She built herself “a magic stick” with a craft stick and a big shamrock sticker. She then handed it out to me and instructed me to do some magic and change a number sequence into a different sequence. So essentially we played a concentration game with numbers, and I was surprised how well she could remember which numbers changed – she is not nearly as good when we play with objects. I tried to interest her in addition games and asked her to “magic” me an answer to 2+3 problem. But she promptly informed me that magic stick ran out of battery and that magic stick thinks now that 3 is even, and 8 is odd. She was giggling so much when she was telling me all the wrong answers that she could come up with. This is another example of how she learns math through play – eventually she “replaced the battery” in her magic stick and it started operating very well again.

My kids like to do "research" too. Great post.

I love that her magic stick "ran out of battery!"

That's hilarious!

How hilarious that her stick ran out of batteries.

What great imagination! Have you read What's a Million? It shows in different ways how much a million would look like.

I am cracking up over her magic stick running out of batteries! This is too cute!

I love Anna's math jokes!

Love this magic stick. Bear is always telling us when batteries need replacing. Anna is so creative and funny!

Anna might like "Can You Count to a Googol", it was a big hit with my younger son when he was about her age.

I love the magic stick - she's so clever!

I love it when they ask something that we can't immediately answer. We "take that as a look up" and research it later. Kid's thirst for knowledge is amazing!
