### **Module 4: Proportional Thinking with Percentages**  
"Welcome to this module on proportional reasoning with percentages!  
Your goal is to solve a real-world problem using different representations:  
1️⃣ **Bar Model**  
2️⃣ **Double Number Line**  
3️⃣ **Equation-Based Approach**  

🚀 **Here’s the problem:**  
Orrin and Damen decided to invest money in a local ice cream shop. Orrin invests $1,500, which is 60% of their total investment. How much do Orrin and Damen invest together?  

💡 **Before receiving guidance, choose a method and explain your reasoning.**  
🚀 **Which method would you like to use first?**  
(Type 'Bar Model,' 'Double Number Line,' or 'Equation' to proceed.)"

### **Bar Model Approach**  
Great choice! The Bar Model is a useful way to visualize proportions and percentages.  
**Now, can you apply the Bar Model and explain your plan?**  
- How would you set up the model?  
- How would you represent the percentages?  
- What steps do you think are needed to find the total investment?  

🚀 **Explain your thinking first, and then I will provide feedback!**

### **Double Number Line Approach**  
Great choice! The Double Number Line helps align percentage values with real-world quantities.  
**Now, can you apply the Double Number Line and explain your plan?**  
- How would you structure the number lines?  
- What values would you place on each line?  
- How do you think this will help you find the total investment?  

🚀 **Explain your thinking first, and then I will provide feedback!**

### **Equation-Based Approach**  
Great choice! Setting up an equation is a powerful way to represent proportional relationships.  
**Now, can you apply the Equation-Based Approach and explain your plan?**  
- What variables would you use?  
- How would you set up the proportion?  
- What would be your first step in solving for the total investment?

🔹 It looks like you might need some help. Here’s how the Bar Model can be used:  
1️⃣ **Draw a bar** representing the total investment.  
2️⃣ **Divide it into 10 equal parts**, since percentages work in 10s.  
3️⃣ **Shade 6 parts** to represent Orrin’s 60% investment.  
4️⃣ **Find the value of 10%**:  
   - Since 60% = $1,500, divide $1,500 by 6.  
5️⃣ **Find 100%** by multiplying the value of 10% by 10.  

💡 What do you think about this approach? Would you like to adjust your method?

🔹 It looks like you might need some guidance. Here’s how the Double Number Line can be used:  
1️⃣ **Draw two parallel number lines** – one for percentages (0% to 100%) and one for dollar amounts.  
2️⃣ **Mark 60% on the percentage line** and align it with $1,500 on the dollar line.  
3️⃣ **Find 10%** by dividing $1,500 by 6.  
4️⃣ **Find 100%** by multiplying 10% by 10.
