  1. Applying Math Skills to Word Problems

  2. I. Analyze the Problem 1 . Read the question carefully Underline key terms and units 2. Define terms and think about their relationship

  3. 3. Identify words that give you clues“sum of” or “product of” 4. Identify the problem to be answered Are their any “sub-questions”?

  4. 5. Determine what principles or concepts the problem involves 6. Analyze the problem Make data tables, draw diagrams, identify units

  5. II. Plan a Solution think about the information given and how each piece is related decide which equation will work for the problem

  6. III. Answer the question • Insert known values • make conversions if needed • do calculations • be sure to label the answer

  7. IV. Evaluate the solution check your answers look for errors be sure that what was asked for in the problem is present in the solution make sure your answer is expressed in the correct number of sig. fig. and the correct units.

  8. For example: You are driving to Lincoln, NE which is 43.5 miles from your home. You estimate that your average speed for the trip will be 55 miles per hour. How long should you allow for the trip to Lincoln in hours? In minutes? • Analyze the problem • Plan a solution • Answer the question or questions • Evaluate the solution
