In this section, we will take a look at your approach, rather than your students', to a task and your use of representation. As you work through the activity, pay attention to the methods you use to think about the problem, the visual representations that you create, your use of numbers to represent the problems, and new insights that you develop. As you complete the tasks, think about how this activity helps you gain insight into the role of visual representations in building understanding and choosing productive forms when problem solving. Keep track of the various representations that you use in your work, and be sure to record questions you ask yourself and things you wonder about.
