So Shoe Me!  

Read the following passage.

There are several different ways to compute shoe sizes. The modern "English" method works like this: The smallest size is size 0, which is a shoe with a length of 4 inches. You add inch to get the next larger size. Sizes run from 0 to 13 and then start over again at 1. About three hundred years ago, English shoe sizes were computed differently. In those days, size 0 was 5 inches long, and you added inch to get the next larger size.

Each group member finds the length in inches of one of his or her own shoes and determines his or her modern English shoe size. Each group member then answers the following question: Suppose that you could travel back in time to the England of three hundred years ago and that you want to buy a pair of fashionable shoes. If you ask for your modern English shoe size, will the shoes you get be too big or too small? How much too big or too small?
