1. Problem Solving Tool:
KFC

2. 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.

3. Problem Solving can be tough but not if you use…K F C

4. 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!”

5. The PLAN you come up with must have two parts!
What operation will I need to use?
Addition, subtraction, division or multiplication
What problem solving strategy will I choose to use?

6. Problem solving strategies!
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

7. 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?

8. First is “K” or “What do you know and need to 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?

9. Know:
Received 4 postcards
Each of 11 trips

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

11. Know: Find out: Received 4 postcards Each of 11 trips
How many postcards did Paul receive from the 11 trips?

12. Last is “C” or “Come up with a plan!”
Remember the plan must have two parts:
What operation will I need to use?
Addition, subtraction, division or multiplication
What problem solving strategy will I choose to use?

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

14. Know: Find out: Come up with a plan! Operation: Strategy:
Received 4 postcards
Each of 11 trips
Find out:
How many postcards did Paul receive from the 11 trips?
Come up with a plan!
Operation:
Multiplication
Strategy:
Draw a picture

15. Paul received 44 postcards.
Now solve!

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

16. Easy right?! Now you try it!
Solve the following problems using KFC! Remember to draw the three column chart and to show your work!
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?

17. Problem Solving can be tough but not if you use…
K F C

18. Draw a Picture Strategy
Air Show Problem 3-1
K F C
8 skydivers How many pieces Operation:
Connect to of ribbon was × ÷ skydivers with used?
ribbon Strategy:
Draw picture
Answer: 56 ÷ 2 = 28 7 6 5 4 3 2 1

19. Working with LD or ELL Students
Use Contextual Clues
Hands-On for Visual Learners
Verbal Interaction
Provide time for students to work collaboratively and discuss assignments
Active Participation
