Different techniques for understanding a problem can lead to ideas for never-used-before solutions. Good problem-solvers use a problem-solving strategy and may come back to it frequently while they are working on the problem to refine their strategy, see if they can find better solutions, or find other questions. Writing is an integral part of understanding the problem and builds momentum in thought. It helps the problem solver organize information and articulate the questions to be addressed when developing a solution. This document includes activities that support students to develop strategies for understanding challenging math problems, along with facilitation suggestions for teachers.
