1 Problem Solving Settles Bridge Fourth Grade

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 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? Read the problem carefully two times!

5 Step 1 - Understand the Problem 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? Underline the question it is asking and circle the key words inside of the question.

6 Step 1 - Understand the Problem 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? Put the question into your own words and then decide on the step(s) and computation sign(s) you will use. 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 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? Cross out any unnecessary sentences.

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 youre going to solve the problem

10 Step 2 - Decide how youre going to solve the problem Use a graphUse formulas Write an equationMake a list Find a patternWork backwards Use reasoningDraw a picture Make a tableAct it out Choose your method. Drawing a picture and/or writing an equation should always be used!

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

12 Step 2 - Decide how youre going to solve the problem $.65 to start$.25 found $.55 for chips Write your equation. Put in a variable for the information that is unknown or the information that you still need. 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! $ 0.65 $ $ 0. $ 0.90 $ $ 0.

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. I will choose to work my problem backwards to check. $ 0.35$ 0.90 $ 0.55$ $ $ 0. I got what I started with so I know I answered my problem correctly!
