Book excerpt: These Working Papers are to be used in the study of chapters 1-26 (bundle of chpt. 1-17 and 18-26) of C21 Accounting Multicolumn Journal Approach. Forms are provided for: Work Together exercises, On Your Own exercises, Application Problems, Mastery Problems, Challenge Problems, and Reinforcement Activities 1 and 2. Printed on each page is the number of the problem in the textbook for which the form is to be used. Also shown is a specific instruction number for which the form is to be used. Century 21's new approach to Working Papers simplifies the paper trail. Each problem has an individual set of working paper pages that can be completed and turned in for grading. We've eliminated the overlap between problems, making it easier for students to complete and teachers to grade. You may not have to use every form that is provided. The pages are perforated so that they can be removed.
