This workbook is designed for the user to develop their fast fact multiplication skills via short practice sets with immediate feedback. To facilitate this, the pages have been arranged so that the questions appear on even numbered pages (left side) with the answers to questions on odd numbered pages (right side).
 
We recommend that you cover or fold back the answer page as you work through each column of questions, then uncover them, check your answers, and record your score. If you follow this procedure, you will find that you will reduce the number of mistakes that you make and you will be more quickly prepared to take and successfully pass the mastery test for this unit.
