Problem Solving is easy if you
      follow these steps


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

          Decide how
            you’re
           going to
           solve the
           problem
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
   Step 2 - Decide how you’re going
          to solve the problem
                    Draw your picture first!
                I have 65
                cents in my
                pocket!




                              Quarter found
This is Anne.                 on the sidewalk.

                                                 55 cents out of
                                                 pocket for these!
 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

             Solve
              The
            Problem
Step 3 - Solve the problem
  Be sure your answer is complete and
           Show your work!
       1                    8 10
 $ 0.65               $ 0.90
 $ 0.25               $ 0.55
 $ 0.90               $ 0.35
Problem Solving is easy if you
      follow these steps


              Look
             Back &
             Check
         Step 4 - Look Back & Check
              Work the problem to check your
                         answer.
                              1                8 10
                           $ 0.35      $ 0.90
                           $ 0.55      $ 0.25
                           $ 0.90      $ 0.6 5
I will choose to work my
 problem backwards to                I got what I started
          check.                       with so I know I
                                    answered my problem
                                          correctly!
