I just skip them!”

Don’t Worry! With just 4 easy steps, you can become…

a Word Problem Whiz!

Step 1UNDERSTAND the problem.

What does the problem ask for? What facts are given?

Here’s an example:

Mr. Gonzales put up a capital coming

from the following:Bank – P250,000.00Private Loan – P100,000.00Personal Money - P150,000.00The cause of merchandise he bought

was P365, 273.00. How much was left from his capital?

What is asked?

How much was left from his capital

What facts are given? Bank – P250,000.00Private – P100,000.00Personal Money - P150,000.00Cause of Merchandise – P 365, 273.00

Step 2Set a PLAN. Identify the hidden question How will you answer the question?

Should you Add, Subtract, Multiply or Divide?

Mr. Gonzales put up a capital coming

from the following:Bank – P250,000.00Private – P100,000.00Personal Money - P150,000.00The cause of merchandise he bought

was P365, 273.00. How much was left from his capital?

What is the hidden question? How much is the total capital of Mr. Gonzales?

What operations are needed?

Addition & subtraction

Carry out the plan!Step 1

Find the total capital of Mr. Gonzales 250,000 + 100,000 + 150,000

Step 2Find the total merchandise Mr. Gonzales bought P 365, 273.00

Step 3 Find the total capital left from Mr. Gonzales

What is the Number Sentence?

If you wrote…(250,000+100,000+150,000) – 365,273 = N

You’re right!

Now that we UNDERSTAND the problem, and have a PLAN, we’re ready for the

next step!

Step 3

Solve it!!!!!Solution: (250,000+100,000+150,000) – 365,273 =

N 500,000 - 365,273 = N 134, 727 = N

Step 4Check !.

Does your answer fit the question?

We have to find out how much

was left from Mr. Gonzales capital.

We added his capital coming from the different sources and subtract it from the total cost he bought for his merchandise.

Our answer was “ P 134,

727.00” .

It makes sense!

We did it!We are Word

Base 1 Juan bought a pair of shoes costing P 925. 00 and

a tie costing P 275.00. He gave the Seller P 2,000.00. How much change did he receive?

2,000- (925.00 + 275.00) = N

Solution:2,000 - (925.00 + 275.00) = N2,000 – 1, 200 = N 800 = N P 800.00 was the change of Juan.

Base 2There are 834 pupils in San Isidro Elementary

School and 675 pupils in Sta. Ana Elementary School. Eight hundred pupils from two schools are girls. How many are boys?

(834 + 675 ) – 800 = N

Solution:(834 + 675 ) – 800 = N 1509 – 800 = N 709 = N

709 are boys from the two schools.

Base 3Five friends decided to share the expenses for their

picnic. They bought 2 kg of shrimp at P 425.00 per kg , a fried chicken at P 225.00 and fruits for P 400.00. How much was each person’s share for the picnic?

[(2x425) + (225 + 400)] ÷ 5 = N

Solution:[(2x425) + (225 + 400)] ÷ 5 = N[ 850 + (225 + 400)] ÷ 5 = N[ 850 + 625] ÷ 5 = N 1475 ÷ 5 = N 295 = N P 295.00 was the share of each person for the picnic
