  2. Problem Solving is easy if you follow these steps Understand the problem

  3. Step 1 – Understand the problem • Read the problem carefully two times. • Underline the question(s) and circle the key words in the question. • Rewrite the questions in your own words and decide on computation sign(s) and steps you will use. • Cross out any unnecessary information and answer the following: What do I already know? What do I need to know? Will my answer be larger or smaller than the starting point? Why?

  4. Step 1 - Understand the Problem Read the problem carefully two times! • Anne always carried her change in her pocket. She had 65 cents. Anne was ready to shop! On her way, she found 25 cents on the sidewalk. From there, she walked into the gas station where she bought a bag of chips for 55 cents. How much money did Anne have left?

  5. Step 1 - Understand the Problem Underline the question it is asking and circle the key words inside of the question. • Anne always carried her change in her pocket. She had 65 cents. Anne was ready to shop! On her way, she found 25 cents on the sidewalk. From there, she walked into the gas station where she bought a bag of chips for 55 cents. How much money did Anne have left?

  6. Step 1 - Understand the Problem Put the question into your own words and then decide on the step(s) and computation sign(s) you will use. • Anne always carried her change in her pocket. She had 65 cents. Anne was ready to shop! On her way, she found 25 cents on the sidewalk. From there, she walked into the gas station where she bought a bag of chips for 55 cents. How much money did Anne have left? This word problem is asking me to find out how much money Anne has left after starting off with 65 cents, finding 25 cents, and then buying chips for 55 cents. My steps that I will use are first adding 25 cents to 65 cents and then subtracting 55 cents from that answer. The computational signs I will use are + then -.

  7. Step 1 - Understand the Problem Cross out any unnecessary sentences. • Anne always carried her change in her pocket. She had 65 cents. Anne was ready to shop! On her way, she found 25 cents on the sidewalk. From there, she walked into the gas station where she bought a bag of chips for 55 cents. How much money did Anne have left?

  8. Step 1 - Understand the Problem Answer the following questions: What do I already know? What do I need to know? Will my answer be larger or smaller then the starting point? Why? • I already know: • She started with 65 cents • She found 25 cents • Then, she paid 55 cents for chips I need to know what is left after she added 25 cents and then spent 55 cents. I think my answer will be smaller then 65 cents because even though she added 25 cents to her pocket, she paid 55 cents for the chips and that was only 10 cents less than what she started with.

  9. Problem Solving is easy if you follow these steps Decide how you’re going to solve the problem

  10. Step 2 - Decide how you’re going to solve the problem Choose your method. Drawing a picture and/or writing an equation should always be used! Use a graph Use formulas Write an equation Make a list Find a pattern Work backwards Use reasoning Draw a picture Make a table Act it out

  11. Step 2 - Decide how you’re going to solve the problem Draw your picture first! I have 65 cents in my pocket! Quarter found on the sidewalk. This is Anne. 55 cents out of pocket for these!

  12. Step 2 - Decide how you’re going to solve the problem Write your equation. Put in a variable for the information that is unknown or the information that you still need. $ .65 to start $ .25 found $ .55 for chips Total left = ? My Equation will look like this: $ .65 + $ .25 - $ .55 = X

  13. Problem Solving is easy if you follow these steps Solve The Problem

  14. Step 3 - Solve the problem Be sure your answer is complete and Show your work! 1 8 $ 0.65 $ 0.25 10 $ 0.90 $ 0.55 $ 0. 9 0 $ 0. 3 5

  15. Problem Solving is easy if you follow these steps Look Back & Check

  16. Step 4 - Look Back & Check Work the problem to check your answer. 8 10 1 $ 0.35 $ 0.90 $ 0.55 $ 0.25 $ 0. 9 0 $ 0. 6 5 I will choose to work my problem backwards to check. I got what I started with so I know I answered my problem correctly!
