| This workbook is a one-of-a-kind resource. It has 138 pages filled with easy-to-follow, step-by-step instructions for identifying and indicating fractional inch measurements from 1/128" to 127/128" on a variety of rulers and professional measuring tapes. There are 550 practice exercises that will enable the reader, upon completion, to demonstrate effortless mastery of the skill. Thousands of people all over the country have taught themselves using this workbook and have gone on to work as manufacturers, carpenters, electricians, plumbers, utility line workers, etc. Recently, the workbook was revised to include a section on the "broken ruler" problem (i.e., when the left edge of an object is not aligned with the zero-line of the ruler); this is a concept with which a majority of school children around the country struggle. A number of middle school students who field-tested this newly added section were able to raise their quiz scores from 0% to 100% after completing 100 fun exercises. |
