Welcome, everyone! Today, we're exploring how case studies can help us apply mathematics in real-world contexts. What do you think a case study could be?
Maybe something like figuring out how to reduce the amount of trash we produce at school?
Or planning a budget for a school event?
Exactly! Case studies analyze specific problems where mathematics can provide insights. They often include real data and help us justify our solutions. Now, let's talk about the first key point: linking theory to practice.
How do we link our math knowledge to real life?
Great question! We apply mathematical concepts through modeling. Think of modeling as translating real-life situations into mathematical terms. Can someone give a simple example?
If I wanted to figure out how many pizzas to buy for a party, I could calculate the total slices needed and then divide by the number of slices in each pizza!
Exactly! By modeling a problem, you're applying your math skills practically. So as a summary, case studies help us apply mathematical concepts in real-world situations by creating models.

These are detailed scenarios that present a specific problem or situation. You'll be given some information and asked to use math to analyze it and propose solutions. Example: Analyzing Social Trends: Your city council wants to predict future housing needs. You might be given population data over the last 20 years.
Detailed Explanation
Case studies are practical exercises where students are presented with a real-life scenario requiring them to apply their mathematical skills. For example, if a city council wants to determine the future housing needs, students might have to analyze population trends over the past 20 years. They would collect data, perhaps create graphs, calculate averages, and use those statistics to project future needs. The emphasis is on applying math to investigate and solve realistic problems.
Examples & Analogies
Think of a case study like preparing for a family trip. Imagine each family member wants to go somewhere different. You gather everyone's preferences and budget, check distances (like plotting a graph), and calculate how much it will cost for gas or tickets to suggest a decision that considers everyone's wishes and the overall budget.

Apply Mathematics: Plot a line graph of population over time (Statistics). Calculate the average annual growth rate (Number/Algebra). Use this rate to predict future population (Algebra/Number).
Detailed Explanation
In applying mathematics to the analyzed scenario, students would use statistics to visualize the data by plotting a line graph. This helps in identifying trends over time. Next, they would calculate the average growth rate to understand how fast the population is increasing annually. Using this growth rate, they can create predictive models to estimate future populations, showing how mathematical formulas and concepts come together to provide insight into real-world issues.
Examples & Analogies
Imagine you have a garden with new plants. You measure their heights every week and plot these measurements on a graph. By observing the line over time, you can see how fast they're growing. If you figure out the average height increase per week, you can predict how tall they'll be in a month, just as predicting population growth uses past growth rates.
Extended Inquiry Tasks Explained

Extended Inquiry Tasks: These are more open-ended. You might be given a broad problem and have to define it, decide what data to collect (or find), choose your own mathematical strategies, and come up with your own innovative solutions.
Detailed Explanation
Extended inquiry tasks challenge students to delve deeper into a broad problem by defining clear questions they want to answer. For example, if tasked with designing a sustainable energy plan for a community, students would research energy needs, available resources, and current technologies. They need to gather, analyze, and interpret data, which requires selecting mathematical strategies appropriate for modeling the energy contributions of different renewable sources. This format emphasizes creativity and innovation in applying mathematics.
Examples & Analogies
Consider planning a big community event. Instead of just ordering pizza, you'd think wider: How many people are attending? What are their food preferences? Look at multiple catering options and costs, and then creatively figure out the best combination of food and budget while ensuring everyone is happy. Itโs not just math; itโs using those calculations in a practical and engaging way.

Identify Problem: How much energy does the community use? How much area is available for solar panels? What's the average wind speed? Model: Calculate the energy output of different types of solar panels or wind turbines (Number/Algebra). Calculate the area needed (Geometry). Model the cost versus savings over time (Financial Math).
Detailed Explanation
When working on extended inquiry tasks, students first need to identify the problem clearly. This involves gathering pertinent questions that will guide their research. For instance, in designing an energy plan, assessing energy use and physical constraints (like available land for solar panels) is essential. Once defined, students model various scenarios by applying number concepts to calculate potential energy outputs from solar panels and turbines using algebra to predict outcomes. They will also examine the geometrical aspects to ensure that resources are utilized efficiently and consider financial implications over a specified timeline.
Examples & Analogies
It's like cooking a big meal: You first assess what ingredients you have and what you want to cook (the problem). Then, you check your recipe book (modeling), ensuring you have enough of each ingredient and calculating whether you need to buy more. Finally, you evaluate if the cost of buying those ingredients fits within your budgetโjust as you would manage energy costs and efficiency in a community plan.
