Solving Problems
Lesson
Topic Index | Grade 3 Math | Elementary Test Prep | StudyZone

Sometimes you need to answer 
more than one question 
in order to solve a problem.

Read the problem carefully 
and decide what information must be found
before you can solve the entire problem.

Determining what the "hidden question" is can help you find a final answer.

Example 1:

The bakery will use 20 sacks of flour preparing for a banquet.
They have 8 sacks in stock.

The flour comes in containers of 4 sacks each. How many containers must the bakery order?

Think:
    What is the "hidden question"?
Decide:
    How many sacks of flour does
    the bakery need?
Work:
        20 - 8 =
12 sacks needed
Then answer the main question:
     How many containers must the
     bakery order?
             12 4  =
3 containers


Example 2:

Willie bought 4 flowers
for his mom.
Each flower cost $2.00.
How much change did he get back from his $10 bill?

Think:
      What is the "hidden question"?
Decide:
    What did the 4 flowers cost?
Work:
       
4 x $2 = $8
Then answer the main
     question:

    
How much change did he get  
     back from his $10 bill?

            
$10 - 8 = $2

 

Remember:

Decide what information you will need
to solve the problem.
