So the other day Graeden and I got on the topic of how big the Earth is. Generally he thinks in terms of feet so I asked him to guess how many feet the world is all the way around. His first guess was 100 feet. I told him that is the size of our hose in the back yard. This helped him put things into a bit better perspective for his next guess. Before I tell you what that was...what do you think? What's the circumference of the Earth in feet (at the equator)?
His next guess was 1 million feet. I really had no idea so I guessed 500,000 feet. He was closer. The Earth is 24,901.55 miles around at the equator, and there are 5,280 feet in a mile, for a total of 131,480,184 feet. Now the next time you're on Jeopardy, and you get that question, you'll have no trouble spouting out the answer.
