In the past, we have conditioned our students to think that there is only one way to solve a problem. In showing students that there can be more than one strategy, we open up opportunities for all students to be successful. As you circulate the room, select strategies that are different and ask those students to show their solution on a large piece of paper. You may even want to select a students' strategy if the solution is incorrect. Giving students the opportunity to review strategies and incorrect solutions, can help students use error analysis to arrive at the correct solution.
