Introduction
Imagine that your family gives you a budget of ₱5,000 for a special shopping trip. You need to buy several important items, but you also see many advertisements offering discounts and special deals.
How can you decide which products are worth buying? How can you determine how much money you are really saving? How can percentages help you make better decisions?
In this WebQuest, you will become a Smart Shopper. You will investigate real-life prices, discounts, and percentage changes using information from the Internet. You will work with your group to analyze the information and create a practical shopping plan.
Your goal is not simply to calculate percentages. You will use mathematics to make a real-life decision.
Task
Working in groups of 3–5 students, you will create a Smart Shopping Plan using a budget of ₱5,000.
Your final product must contain:
- At least five products that your group would like to purchase.
- The original price of each product.
- At least one discount or percentage change for each product.
- The amount of discount or increase.
- The final price after applying the percentage.
- The total amount spent.
- The amount of money saved, if applicable.
- A short explanation of why your group selected those products.
Your final output may be presented as a digital poster, infographic, PowerPoint presentation, or Google Slides presentation.
At the end, your group will answer this question:
How can understanding percentages help people make better decisions when shopping and managing money?
Process
Step 1 – Organize Your Group
Form a group of 3–5 members and assign responsibilities.
Suggested roles:
- Researcher – searches for product information and prices.
- Calculator – checks the percentage computations.
- Recorder – organizes the information in a table.
- Designer – prepares the final presentation.
- Presenter – explains the group's findings.
Members should still work together and check one another's work.
Step 2 – Review Percentage Concepts
Before starting the investigation, review the following:
- Percentage
- Rate
- Base
- Percentage increase
- Percentage decrease
- Discount
Make sure that everyone in the group understands how percentage calculations are performed.
Step 3 – Search for Real-Life Information
Use the Internet to find products and prices from reliable websites.
Look for examples of:
- Sale prices
- Discounts
- Price increases
- Promotional offers
- Household expenses
Record the source of your information.
Step 4 – Select Your Products
Choose at least five products that your fictional family might reasonably purchase.
Examples include:
- School supplies
- Clothing
- Food
- Appliances
- Household products
- Electronic accessories
Your total budget is ₱5,000, so you need to make practical choices.
Step 5 – Calculate the Percentages
For every selected product, determine:
Original Price × Discount Rate = Discount Amount
Then:
Original Price − Discount Amount = Sale Price
Show your complete solution.
Step 6 – Compare Your Choices
Discuss the following questions:
- Which product gives the biggest savings?
- Which product has the highest percentage discount?
- Did the biggest discount always result in the biggest peso savings?
- Did your group stay within the ₱5,000 budget?
- Which purchases were necessary and which were optional?
Step 7 – Prepare Your Smart Shopping Plan
Organize your findings in a table such as:
| Product | Original Price | Discount | Discount Amount | Final Price |
|---|---|---|---|---|
| Product 1 | ₱___ | ___% | ₱___ | ₱___ |
| Product 2 | ₱___ | ___% | ₱___ | ₱___ |
| Product 3 | ₱___ | ___% | ₱___ | ₱___ |
| Product 4 | ₱___ | ___% | ₱___ | ₱___ |
| Product 5 | ₱___ | ___% | ₱___ | ₱___ |
Add your recommendations and explanations.
Step 8 – Present Your Findings
Present your Smart Shopping Plan to the class.
Your group should explain:
- How you calculated the percentages
- How you decided which products to buy
- How much money you spent
- How much money you saved
- Why your choices were practical
Evaluation
| Criteria | 4 – Excellent | 3 – Good | 2 – Developing | 1 – Beginning |
|---|---|---|---|---|
| Mathematical Accuracy | All computations are correct and complete. | Most computations are correct. | Several computational errors are present. | Many computations are incorrect. |
| Application of Percentage | Percentage concepts are applied accurately to realistic situations. | Application is mostly correct. | Some application errors are present. | Percentage concepts are poorly applied. |
| Research and Resources | Uses reliable sources and records information clearly. | Uses appropriate sources. | Uses limited sources. | Sources are missing or inappropriate. |
| Final Product | Very clear, organized, creative, and complete. | Clear and complete. | Some parts are unclear or incomplete. | Disorganized or incomplete. |
| Explanation and Presentation | Explains computations and decisions clearly and confidently. | Explains most ideas clearly. | Explanation lacks some important details. | Explanation is unclear or incomplete. |
| Group Participation | All members participate actively and responsibly. | Most members participate. | Participation is uneven. | Very limited cooperation. |
Conclusion
You have completed the Smart Shopper WebQuest!
Through this activity, you discovered that percentages are not only mathematical concepts found in textbooks. They are useful in everyday life when people compare prices, calculate discounts, manage budgets, and make financial decisions.
Take a moment to reflect:
What did I learn about percentages from this activity?
How can I use percentage skills in my daily life?
What was the most challenging part of the activity?
How did working with my group help me learn?
How will I use what I learned the next time I shop or manage money?
The purpose of this WebQuest is to help students investigate, analyze information, solve problems, and apply mathematics to an authentic situation, rather than simply memorize procedures. This follows the WebQuest format in your assignment: Introduction, Task, Process, Resources, Evaluation, and Conclusion.
