### **Module 3: Proportional Reasoning Problem Types** | |
#### **Task Introduction** | |
"Welcome to this module on proportional reasoning problem types! | |
Your task is to explore three different problem types foundational to proportional reasoning: | |
1️⃣ **Missing Value Problems** | |
2️⃣ **Numerical Comparison Problems** | |
3️⃣ **Qualitative Reasoning Problems** | |
You will solve and compare these problems, **identify their characteristics**, and finally **create your own problems** for each type. | |
🚀 **Let's begin! Solve each problem and analyze your solution process.**" | |
--- | |
### **🚀 Solve the Following Three Problems** | |
📌 **Problem 1: Missing Value Problem** | |
*"The scale on a map is **2 cm represents 25 miles**. If a given measurement on the map is **24 cm**, how many miles are represented?"* | |
📌 **Problem 2: Numerical Comparison Problem** | |
*"Ali and Ahmet purchased pencils. Ali bought **10 pencils for $3.50**, and Ahmet purchased **5 pencils for $1.80**. Who got the better deal?"* | |
📌 **Problem 3: Qualitative Reasoning Problem** | |
*"Kim is mixing paint. Yesterday, she combined **red and white paint** in a certain ratio. Today, she used **more red paint** but kept the **same amount of white paint**. How will today’s mixture compare to yesterday’s in color?"* | |
--- | |
### **🚀 Step-by-Step Solutions** | |
#### **Problem 1: Missing Value Problem** | |
We set up the proportion: | |
$$ | |
\frac{2}{25} = \frac{24}{x} | |
$$ | |
Cross-multiply: | |
$$ | |
2 \times x = 24 \times 25 | |
$$ | |
Solve for \( x \): | |
$$ | |
x = \frac{24 \times 25}{2} = \frac{600}{2} = 300 | |
$$ | |
or using division: | |
$$ | |
x = 600 \div 2 = 300 | |
$$ | |
**Conclusion:** *24 cm represents **300 miles**.* | |
--- | |
#### **Problem 2: Numerical Comparison Problem** | |
**Calculate unit prices:** | |
$$ | |
\text{Cost per pencil for Ali} = \frac{3.50}{10} = 0.35 | |
$$ | |
$$ | |
\text{Cost per pencil for Ahmet} = \frac{1.80}{5} = 0.36 | |
$$ | |
or using the division symbol: | |
$$ | |
\text{Cost per pencil for Ali} = 3.50 \div 10 = 0.35 | |
$$ | |
$$ | |
\text{Cost per pencil for Ahmet} = 1.80 \div 5 = 0.36 | |
$$ | |
**Comparison:** | |
- Ali: **\$0.35** per pencil | |
- Ahmet: **\$0.36** per pencil | |
**Conclusion:** *Ali got the better deal because he paid **less per pencil**.* | |

#### **Problem 3: Qualitative Reasoning Problem** | |
🔹 **Given Situation:** | |
- Yesterday: **Ratio of red to white paint** | |
- Today: **More red, same white** | |
🔹 **Reasoning:** | |
- Since the amount of **white paint stays the same** but **more red paint is added**, the **red-to-white ratio increases**. | |
- This means today’s mixture is **darker (more red)** than yesterday’s. | |
🔹 **Conclusion:** | |
- *The new paint mixture has a **stronger red color** than before.* | |
--- | |
### **🔹 Final Reflection** | |
*"Now that you've explored these problem types, let's discuss how you might use them in your own teaching or learning."* | |
- "Which problem type do you think is the most useful in real-world applications?" | |
- "Would you like to try modifying one of these problems to create your own version?" | |
- "Is there any concept you would like further clarification on?" | |
*"I'm here to help! Let’s keep the conversation going."* | |
