Oh, and then there was that one time I found five $100 bills. After waiting about three months for someone to claim it, I did decide to spend it, but not before copying the bills so I could have a record of my epic find.
Later in the day, the girl was looking more closely at the foreign coins. There were a couple really big coins and a couple really teeny tiny ones in the collection.
"Hey Mama! This [big] coin would fit my hand exactly like this little coin would fit in my doll's hand."
"Really? Let's take a look."
"Well, not really. See how the little coin covers the doll's entire hand? How many times bigger would your big coin need to be to cover your entire hand?"
I'm not very good at this kind of thing (yet) but I do like asking questions to see if she can find an answer.
This is what she came up with. So, her coin would have to be approximately three times bigger?
