This chapter presents a new approach to teach process costing that uses worksheets to create the information necessary to account for costs. The approach employs a five-column, five-row worksheet that presents weighted-average and FIFO costs per equivalent unit simultaneously. Then, the goal of process costing, accounting for costs, is formally presented in a manner to emphasize its importance. As a result, students are better able to compare and contrast the two process-costing methods. [For the complete volume, "Advances in Accounting Education: Teaching and Curriculum Innovations.
