"Visualizing huge numbers can be very difficult. People regularly talk about millions of miles, billions of bytes, or trillions of dollars, yet it's still hard to grasp just how much a "billion" really is."

The MegaPenny Project aims to help by taking one small everyday item, the U.S.A. penny, and building on that to answer the question: "What would a billion (or a trillion) pennies look like?"

Note: All weights and measurements are U.S.A. standards, not metric.

If you and/or your learners are looking for a site to teach about large numbers or just curious to see what a trillion pennies looks like, head over to The Mega Penny Project at http://www.kokogiak.com/megapenny/default.asp.
