The Problem Solving and Communication Activity Series Work Backwards
Work Backwards
When "work backwards" applies to a problem, it's a really powerful strategy. The key is to ask, "what must have happened right before that?" We offer students techniques for visualizing problems, and then visualizing them backwards. We also offer some ideas for those tricky problems where you know what's given and what you're trying to get, but you don't know the steps in between. Working backwards can help in those situations as well. Activities to Learn this Strategy
