3. Read the problem below.
Problem 1: (Example of solving routine word
problem)
A farmer named Pablo is selling all of his
crops for Php 13,490.50. When he brought his
crops to Rawis Fair Market in Calbayog City, a
businessman took all of his crops and only paid
Php 5,940.70. How much is the businessman’s
balance to pay to Pablo?

4. To answer them correctly you should master the skill
of identifying the things what are being asked in each
problem.
Step 1: Identify what is asked.
Step 2: List down what are given.
Step 3: Identify the hidden question, if
there is any.
Step 4: Identify the operation needed to
solve the problem.
Step 5: Write the mathematical sentence
that will be used to solve the problem.
Step 6: Solve the problem.

5. Solution of the problem:
Step 1: Identify what is asked.
- The amount of money the businessman still
has to pay to Pablo
Step 2: List down what are given.
- Php 13,490.50 – The price of Pablo’s crops
- Php 5,940.70 – The amount of money the
businessman paid
Step 3: Identify the hidden question, if there is
any.
- There is no hidden question in the problem.

6. Step 4: Identify the operation needed to
solve the problem.
- Subtraction
Step 5: Write the mathematical sentence
that will be used to solve the problem.
N = 13,490.50 – 5,940.70
N= the amount of money the
businessman still has to pay to Pablo.

7. Therefore,
- The businessman still needs to pay
Pablo the amount of Php 7, 549.80

8. Consider the problem below
Pedro lives in far flung barangay of
Calbayog City. Sometimes he went to
school early with an empty stomach.
Upon arriving at school, that’s the time
that he will look for something to eat

₱120.50 for his food in the morning and
₱150.25 during lunchtime. How much did
Pedro spend in total for his food?

9. How much did Pedro spend in total for his food?
₱120.50 for his food in the morning and
₱150.25 during lunchtime.
There is no hidden questions.
Addition
₱120.50 + ₱150.25 = N

10. ₱120.50
+ ₱150.25
₱270.75
Therefore:
Pedro spend 270.75
₱ for his
food.

11. Read the problem carefully and answer the following
questions.
Cristina wants to buy shoes for her sister as a birthday

buy the shoes?
Step 1: Identify what is asked.
Step 2: List down what are given.
Step 3: Identify the hidden question, if there is any.
Step 4: Identify the operation needed to solve the problem.
Step 5: Write the mathematical sentence that will be used to solve
the problem
Step 6: Solve the problem.

18. Solving Non-routine Word Problems
Non-routine problems can be solved in multiple
ways and with a variety of strategies. Different
strategies are used in solving non-routine word
problems.
● Look for a pattern
● Guess and check
● Work backward
● Make a model/ visualize the problem
● Break up the problem into smaller parts and
solve each part

22. Consider the other example
below.
Eric earned Php 1,305.40 from
working at a restaurant. He gave
Php 350.00 to his mother and
paid Php 524.60 for their electric
bill. How much money was left
for Eric’s savings?

23. How much money was left for Eric’s savings?
₱1305.40 –earnings of Eric
₱350.00 –money gave to his mother
₱524.60 – payment for bills.
No Hidden questions
Subtraction
₱ 1305.40 - ₱350.00 - 524
₱ .60 = N

24. ₱1305.40
₱ 350.00
- 524.60
₱
₱ 430.80
Therefore:
₱430.80 was left from Eric’s
Savings..

25. Read the problem carefully and answer the following questions.
Katherine wants to buy a present for his best friend’s

more does she need to be able to buy the present?
Step 1: Identify what is asked.
Step 2: List down what are given.
Step 3: Identify the hidden question, if there is any.
Step 4: Identify the operation needed to solve the problem.
Step 5: Write the mathematical sentence that will be used to
solve the problem
Step 6: Solve the problem.
