Strategies for
Solving Word
Problems
In your group:
In your group:
• Discuss the difficulties you
have when you try to solve
word problems?
• One person from each
group list those difficulties
on the board.
Operation Words
These words can be helpful for you to
determine what operation will be used in
a problem.
However, you still need to understand
what the word problem “means”.
The operation words sometimes can be
mistaken for the wrong operation.
Watch out for misreading the wrong key word!
Example
Toby buys two books at Top‟s
Bookstore. They cost $12.85
together. He pays with a $20 bill.
How much change does Toby
receive?
$12.85 + $20 = $32.85
Correct solution: $20 -$12.85 = $ 7.15
Wrong solution:
Different Math Strategies
Make a List
Use Object/Act It Out
Make a Drawing/Use a Model
Make a Table
Make a Graph
Guess and Check/Experiment
Work Backward
Use a Pattern
Use Logic
Make a Model ~ Not the only
method to solve word
problems, but it can be used to
solve most word problems
(about 80%)
“A picture (or a diagram)
is worth a thousand
words.”
The 8 Step Process
1.Read the entire
problem.
Alicia had $6 more than Bobby. If
Bobby had $10, how much did
they have altogether?
2.Decide who is involved in
the problem.
Alicia had $6 more than Bobby. If Bobby had
$10, how much did they have altogether?
Alicia
Bobby
3.Decide what is involved in
the problem.
Alicia had $6 more than Bobby. If
Bobby had $10, how much did they
have altogether?
Alicia’s money
Bobby’s money
4.Draw unit bars of equal
length.
Alicia had $6 more than Bobby. If
Bobby had $10, how much did
they have altogether?
Alicia’s money
Bobby’s money
5.Read each sentence, one at
a time.
Alicia had $6 more than
Bobby. If Bobby had $10,
how much did they have
altogether?
Alicia’s money
$10
Bobby’s money
$10
$6
6.Put the question mark in
place.
Alicia had $6 more than
Bobby. If Bobby had $10,
how much did they have
altogether?
Alicia’s money
$10
Bobby’s money
$10
$6
?
7.Work the computation to the
side or underneath.
Alicia had $6 more than
Bobby. If Bobby had $10,
how much did they have
altogether?
Alicia’s money
$10
$6
$10 + $10 = $20
$20 + $6 = $26
OR
Bobby’s money
$10
$10 + $6 = $16
$16 + $10 = $26+
$10 =
8.Answer the question in a
complete sentence.
Alicia had $6 more than Bobby. If
Bobby had $10, how much did they
have altogether?
Alicia and Bobby had $26 altogether.
