The easiest way I have found to explain an inch is to draw it out, starting with a mark representing zero and a mark representing 1. These DO NOT HAVE TO BE ACCURATE!!! I find it is a lot easier if you make your "inch" BIG to give you more room to write in the fractions. SO:
On the paper, Draw a rectangle as shown in Picture 2 and 3. This is going to be our "ruler". Remember to make it big! On the ruler, make a mark, also as shown in Pictures 2, 3, and 4. This will be out 1 inch mark.
