A teacher can use Doceri software to show multiple solutions to the same problem with different answers, and replay the solutions back to discuss the different steps. The teacher can rewind the writing and drawing to replay the solutions, step by step, to find the errors and fix them. Solving the problem in two ways provides a way to check her work for accuracy. Playing back the solutions helps the students see the process unfold more than once, so that they can see when errors occurred in time, and not just spatially on paper or a white board. The problem is solved directly over electronic PDF file on the computer desktop. Visit www.doceri.com for more information on this software. Thank you to Mrs. Zorin from Stevens Elementary school for her math work sheet.
