##### Presentation Transcript

1. What is Problem Solving? • Problem solving is when you are presented with a math problem and you have to figure out a way to answer the question that the problem is asking you.

2. Problem Solving can be tough but not if you use… • K • F • C • S

3. No, not fried chicken! • K- stands for “What information do I know?” • F- stands for “What am I trying to find out?” • C- stands for “Come up with a plan!” • S- stands for Use strategy and “Solve!”

4. The PLAN you come up with must have two parts! • What operation will I need to use? Addition, subtraction, division, multiplication, ordering, comparing, and/or estimating …? • What problem solvingstrategy will I choose to use?

5. Act it out Draw a picture Solve a Simpler Problem Use Logical Reasoning Work Backward Write an Equation Write a Number Sentence Make an Organized List Make a Table / Chart / T-Chart Use Estimation Use Mental Math Make a Number Line Find a pattern Guess and Check Problem solving strategies!

6. Let’s try it! Here’s the problem: • Paul received four postcards from each of his father’s 11 trips. How many postcards did Paul receive from the 11 trips?

7. First is “K” or “What do you know and needto solve the problem?” • Paul received four postcards from each of his father’s 11 trips. How many postcards did Paul receive from the 11 trips?

8. Next is “F” or “What am I trying to findout?” • Paul received four postcards from each of his father’s 11 trips. How many postcards did Paul receive from the 11 trips?

9. Next is “C” or “Come up with a plan!” Remember the plan must have two parts: • What operationwill I need to use? Addition, subtraction, division, multiplication, ordering, comparing, and/or estimating …? • What problem solvingstrategywill I choose to use?

10. How do we choose an operation?Look for KEY words!

11. Now it’s time to solve the word problem!

12. O O O O O O O O O O O O O O O O O O O O O O O O O O O O O O O O O Four groups of 11 is 44. 4 x 11 = 44 Paul received 44 postcards. O O O O O O O O O O O

13. Easy right? Now you try it! Solve the following problems using KFCS on the KFCS Chart your teacher has given you using the first strategy we have learned. Draw a Picture 1. There were 6 chickens and 8 horses on Mr. Johnson’s farm. What is the total number of legs on Mr. Johnson’s farm? (hint: include Mr. Johnson) 2. Ringo, John, Paul, and George are singing in a band. John and Paul have on glasses. Paul and Ringo are standing beside of John. George doesn’t want to stand beside John because he sings off key. Ringo is standing on the end. What order are they standing on stage?
