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?
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.
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.
