Millions, Billions and Trillions

Today we tackled the concept of millions, billions and trillions. The students estimated how long it would take them to tap their desk one million times, then a billion times, then a trillion times. To illustrate the difference between a million, billion and a trillion we used this web site http://www.pagetutor.com/trillion/index.html The website is not exactly what we were looking for because the illustration uses a trillion dollars in $100's. It did serve the purpose. Thought you might like to see it.
