Financial Math: Comparing Quantities & Independent Learning

Grade 7Math3 days
In this 7th-grade math project, students become informed consumers by applying mathematical tools like ratios, proportions, and percentages to real-world shopping scenarios. They analyze discounts and GST, plan a class event within a budget, and compare prices between stores. Through portfolio activities, students investigate price comparisons, decode festival sale discounts, and explore simple interest savings, culminating in a financial literacy portfolio assessed via a detailed rubric.

Inquiry Framework

Question Framework

Driving Question

The overarching question that guides the entire project.How can we, as informed consumers, use mathematical tools like ratios, proportions, percentages, and GST to analyze real-world shopping scenarios, make financially sound decisions, and plan a class event within a budget?

Essential Questions

Supporting questions that break down major concepts.
  • How can percentages help us make informed decisions about spending and saving money?
  • In what ways can understanding discounts and GST impact our budgeting and financial planning?
  • How do ratios and proportions help us compare prices and understand value for money?

Standards & Learning Goals

Learning Goals

By the end of this project, students will be able to:
  • Apply ratios and proportions to compare prices and understand value for money.
  • Analyze the impact of discounts and GST on budgeting and financial planning.
  • Make informed decisions about spending and saving money using percentages.
  • Plan a class event within a budget of Rs 2,000, incorporating GST calculations for various items and services.
  • Calculate percentage increase or decrease in prices between two stores for selected items.
  • Calculate discount amount, final price, and total savings for items sold during festival sales.

Entry Events

Events that will be used to introduce the project to students

Mystery Shopper Challenge

Students receive a 'secret mission' envelope containing a shopping list and a budget. They must visit local stores (real or simulated) to find the best deals, calculate discounts, and determine the most cost-effective way to purchase all items. This activity sparks immediate engagement with real-world financial decisions.

The Case of the Missing Percentage

A local business owner presents a 'problem' – a discrepancy in their sales records due to incorrectly calculated discounts or taxes. Students work in teams as financial detectives to analyze the data, identify the errors, and restore the business owner's confidence in their financial reporting. This scenario challenges conventional thinking about math's relevance.

The Great Gadget Discount Duel

Introduce a scenario where two competing stores offer different discounts on the same popular gadget. Students must analyze the discount structures (e.g., percentage off vs. fixed amount off) to determine which store offers the better deal. This event promotes critical thinking and mathematical application in a competitive and relatable context.

Portfolio Activities

Portfolio Activities

These activities progressively build towards your learning goals, with each submission contributing to the student's final portfolio.
Activity 1

Price Comparison Investigator

Students will become price comparison investigators, researching and comparing the prices of everyday items at different stores to identify the best deals using percentage calculations.

Steps

Here is some basic scaffolding to help students complete the activity.
1. Select 5 items that you regularly buy or are of interest to you.
2. Visit (or virtually browse) two different stores to research and record the prices of each item. Ensure the stores are comparable (e.g., two supermarkets, two online retailers).
3. Calculate the percentage increase or decrease in price for each item between the two stores. Use the formula: [(Price at Store B - Price at Store A) / Price at Store A] x 100.
4. Create a comparison table showing the item, prices at both stores, and the calculated percentage difference. Clearly label each column.
5. Construct a double bar graph to visually represent the price comparison between the stores. Ensure the graph has a title, labeled axes, and a key.

Final Product

What students will submit as the final product of the activityA detailed price comparison report including a table of prices, percentage differences, and a double bar graph, highlighting which store offers better deals for each item.

Alignment

How this activity aligns with the learning objectives & standardsApplies ratios and proportions to compare prices and understand value for money. Calculates percentage increase or decrease in prices between two stores for selected items.
Activity 2

Festival Sale Discount Decoder

Students will analyze festival sale discounts to determine the final price and total savings on selected items, enhancing their understanding of discount calculations.

Steps

Here is some basic scaffolding to help students complete the activity.
1. Select 3 items that are commonly sold during festival sales (e.g., electronics, clothing, home goods).
2. Research and record the original price, discount percentage, and any additional offers (e.g., 'buy one get one free') for each item from a specific store or advertisement.
3. Calculate the discount amount for each item by multiplying the original price by the discount percentage. Then, calculate the final price of each item after applying the discount.
4. Determine the total savings for each item by subtracting the final price from the original price.
5. Design a visually appealing poster showcasing the original prices, discounts, final prices, and total savings for the selected items. Include a catchy title and clear presentation of the information.

Final Product

What students will submit as the final product of the activityA poster presentation showcasing the original prices, discounts, final prices, and total savings for the selected items, demonstrating an understanding of discount calculations.

Alignment

How this activity aligns with the learning objectives & standardsAnalyzes the impact of discounts and GST on budgeting and financial planning. Calculates discount amount, final price, and total savings for items sold during festival sales.
Activity 3

Simple Interest Savings Challenge

Students explore simple interest by planning a savings strategy for a specific goal, calculating interest earned over time.

Steps

Here is some basic scaffolding to help students complete the activity.
1. Define a savings goal (e.g., buying a game, a book, or contributing to a larger purchase) and determine the amount needed.
2. Research different simple interest rates offered by banks or credit unions (can be simulated).
3. Choose a principal amount to 'invest' (e.g., money earned from chores or allowance).
4. Calculate the simple interest earned over a set period (e.g., 1 year, 2 years) using the formula: Simple Interest = Principal x Rate x Time.
5. Create a savings plan showing the initial amount, interest rate, time period, and total savings (principal + interest) at the end of the period. Present findings in a table or chart.

Final Product

What students will submit as the final product of the activityA detailed savings plan outlining the savings goal, principal, interest rate, time period, and projected total savings using simple interest calculations.
