STAR
is an example of an empirically validated (Maccini & Hughes, 2000; Maccini
& Ruhl, 2000) first-letter mnemonic that can help students recall the
sequential steps from familiar words used to help solve word problems involving
integer numbers.
The steps for STAR include:
Search the word problem;
Translate the problem;
Answer the problem; and
Review the solution
Below is an example of a
structured worksheet using STAR strategy in solving word problem:
Objective: Solve 2- to 3-
step word problems involving whole numbers (BEC PELC II. A.1.2)
Problem: Mr. Cruz had
P4,500. He spent P2,500 for food; P750 for transportation; and P275 for other
expenses and divided the rest among his 5 brothers. How much was the share of
each?
Strategy Questions:
S-earch
the word problem
a.
Read the problem carefully
b.
Ask yourself questions: "What do I know?
What do I need to find?"
c.
Write down the facts:
·
Mr. Cruz had P4,500.
·
He spent P2,500 for food
·
P750 for transportation
·
P275 for other expenses
·
He divided the rest among his 5 brothers
I
need to find share of each brother.
T-ranslate
the words into an equation in picture form.
P2,500-food
|
P750-transportation
|
P275-
other expenses
|
n=divided
among 5 brothers
|
A-nswer
the problem
If I add all Mr. Cruz’s expenses
and subtract the sum from his original money, I can get the amount that was
shared by his five brothers and divide this by 5.
Mr. Cruz’s expenses: P2,500
+ P750 + P275 = P3,525
P4,500 - P3,525=P975
P975 ÷ 5 = P195
Each brother receives P195.
R-eview the Solution
a.
Reread the problem
b.
Ask yourself questions: "Does the answer
make sense? Why?"
c.
Check the answer
I checked my answer.
When I multiplied P195 by 5
and added the product to the total of Mr. Cruz’s expenses, I got P4500 which is
Mr. Cruz’s total amount.
P.S. I also made posters about STAR Strategy that teachers could post in their walls. I hope you would find these useful.
