Chapter 1 Lesson 1 A Plan for Problem Solving

Four Step Plan: Explore: Read the problem carefully. Ask yourself questions like, “What facts do I know? ” and “What do I need to find out? ” Plan: See how the facts relate to each other. Make a plan for solving the problem. Estimate the answer. Solve: Use your plan to solve the problem. If your plan does not work, revise it or make a new plan. Examine: Reread the problem.
