How to "Read" a Ruler workbook

This workbook is a one-of-a-kind resource:  it has 112 pages filled with easy-to-follow, step-by-
step instructions for determining fractional inch measurements from 1/128 " to 127/128 "
and 367 practice exercises that will enable the reader to demonstrate effortless mastery of
the skill.  Thousands of adults all over the country have taught themselves using this workbook
and have gone on to work in manufacturing, or to become carpenters, electricians, plumbers,
utility line workers, etc.  Recently, the workbook was revised to include a section on the
"broken ruler" issue (i.e., when the object is not aligned with the zero-line of the ruler), and a
number of middle school students were able to raise their quiz scores from 0% to 100%
after completing 100 exercises.
