Sec. 1.7 4-step problem-solving plan
1. Learning Target:Students will learn the 4-step problem solving plan to solve many kinds or problems.Students will learn a number of different problem solving strategies.
3. (1) UNDERSTAND the Problem What do you know? What do you need to find out?
4. (2) Develop a PLAN Have you ever solved a similar problem? What strategies can you use? Estimate an answer.
5. (3) SOLVE the Problem Do you need to try another strategy? What is the solution?
6. (4) LOOK BACK Did you answer the right question? Does your answer make sense?
7. Kitty Litter Kitty Litter had 9 people come to her party. Everyone there shook hands one time with every person. How many total handshakes were there at the party?
8. (1) UNDERSTAND the Problem What do you know? 9 people came (10 total) Everyone shook hands with each other What do you need to find out? Total number of handshakes
9. (2) Develop a PLAN Have you ever solved a similar problem? Not that I can remember What strategies can you use? Write a numerical equation Estimate an answer. A two digit number less than 90 ( 9 X 10 = 90 but I know there are repeats)
10. (3) SOLVE the Problem 9+8+7+6+5+4+3+2+1 = 45 Do you need to try another strategy? No, I feel confident about my answer What is the solution? 45 handshakes
11. (4) LOOK BACK Did you answer the right question? Yes, I found the total handshakes Does your answer make sense? Yes, it is a two digit number less than 90
12. Now I want you to solve this exact same problem using a different strategy. Notice that you already have the solution so I want you to focus on is the process. It is just as important as the solution.Before I let you go lets generate a list of possible strategies you could use that you might have used in the past.
13. Strategies Look for a Pattern Guess and Check Solve a simpler Problem Draw a picture/use a model Make an organized list/table Work backward Act it out/use objects Use logical reasoning (if… then…)(hints/clues) *Problem Solving Handbook pg. 761*
14. Can you recall the 4-step problem solving plan and the different problems solving strategies we talked about today?
