I tried the 1 billion on a number line with my gr. 8/9 class. I let them tell me where to make the marks and we looked at all the marks. Then I showed them what the numbers 1 trillion and 1 billion looked like. We tried it again. Finally, I showed them the answer. They were astounded. It was a great eye opener for me.
