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.

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

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.
