  1. What are the steps in the Four Step Plan to solve math problems? Miss Hartgrove Hanes Middle School

  2. Lesson Outline Today we are going to… • Talk about what it means to solve problems. • Learn the best way to solve math problems. • Use our new problem solving plan to solve math problems.

  3. What do you already know about problem solving?

  4. What do you want to learn about problem solving?

  5. The Four Step Plan to Solving Math Problems • To help us solve math problems that we encounter in class, we are going to use a problem solving plan. • This plan gives you a step-by-step guide to solving any math problem. • If you use this plan, I can guarantee that you will be able to solve math problems!

  6. Step One: Explore In Step One you should identify the following information. • Read the problem • What do you know? • What do you need to find out?

  7. Step Two: Plan In Step Two you should identify the following information: • How can you solve the problem? • Estimate an answer.

  8. Step Three: Solve In Step Three you should identify the following information: • Solve the problem. What strategy did you use? • What is the solution?

  9. Step Four: Examine In Step Four you should identify the following information: • Re-read the problem. • Does the answer make sense? • Check your answer • Make a new plan if needed!

  10. Let’s Practice with an Example: Using the example word problem on the board, I am going to show you how we use the Four Step Plan. After this example, you will help me to solve a word problem using our checklist.

  11. Example: John collects toy trains. He already has 10 trains in his collection. For his birthday, his parents gave him 5 more trains. John also gets 3 trains from his aunt. While playing with the trains, 2 of them break. How many unbroken trains does John have?

  12. Step One: Explore • Read the problem • What do you know? He has 10 trains His parents gave him 5 trains His aunt gave him 3 trains 2 trains broke • What do you need to find out? How many trains does he have that are unbroken.

  13. Step Two: Plan • How can you solve the problem? Add up the trains he has and that he was given. Subtract the 2 trains that broke from that total.

  14. Step Three: Solve • Solve the problem. • What strategy did you use? 10 + 5 + 3 = 18 (total number given) 18 – 2 = 16

  15. Step Four: Examine • Re-read the problem. • Does the answer make sense? Yes, the answer make sense. • Check your answer. 16 + 2 = 18 18 – 5 – 3 = 10 (The answer is correct because the number equals the number of trains he had originally.)

  16. Let’s Practice! Use the example problem below to help me complete the graphic organizer and solve the problem. Billy read 3 books over the summer. Each book took him 3 weeks to read. How many weeks did it take Billy to read all 3 books?

  17. Step One: Explore • Read the problem • What do you know? • What do you need to find out?

  18. Step Two: Plan • How can you solve the problem?

  19. Step Three: Solve • Solve the problem.

  20. Step Four: Examine • Re-read the problem. • Does the answer make sense? • Check your answer.

  21. Independent Practice Work with your small group to solve the problem below. Use the graphic organizer in your blue folder to solve the problem. Susan babysits for her neighbors. She earns $10.00 for each hour she works. If Susan worked 3 hours, how much money did she make?

  22. Step One: Explore • Read the problem • What do you know? • What do you need to find out?

  23. Step Two: Plan • How can you solve the problem?

  24. Step Three: Solve • Solve the problem.

  25. Step Four: Examine • Re-read the problem. • Does the answer make sense? • Check your answer.
