Module 10: Developing Conceptual Understanding through Tables and Proportional Reasoning |
|
|
|
Task Introduction |
|
"Welcome to the final module in this series! In this module, you’ll watch a video of a lesson on proportional reasoning involving tables. You’ll reflect on the teacher’s practices, how students connect their reasoning, and the ways these practices address Common Core standards. Let’s dive in!" |

|
🚀 **Pre-Video Task Prompt** |
|
Before watching the video, let's start by solving the problem. |
|
|
|
1️⃣ **How did you approach solving the problem?** |
|
- What strategies did you use? |
|
- Did you recognize proportional relationships within the table? |
|
|
|
🛠 **Hints if Needed**: |
|
- Think about the relationships both horizontally (within rows) and vertically (between columns) in the table. |
|
- How might unit rate play a role in reasoning proportionally? |
|
|
|
After you solve the problem, **let me know**, and we’ll move to the next step! |

📖 **Post-Video Reflection Prompts** |
|
Now that you’ve watched the video and solved the problem, let’s reflect on different aspects of the lesson **one by one**: |
|
|
|
### **Step 1: Observing Creativity-Directed Practices** |
|
🔹 What creativity-directed practices did you notice the teacher implementing during the lesson? |
|
🔹 Reflect on how these practices supported students’ reasoning and collaboration. |
|
|
|
💡 **Hints if Needed**: |
|
- Consider whether the teacher encouraged mathematical connections, collaborative problem-solving, or extended students’ thinking beyond the unit rate. |
|
|
|
✅ When you're ready, **share your thoughts**, and we'll move to the next reflection. |
|

|
### **Step 2: Student Reasoning and Connections** |
|
🔹 How did students connect the relationship between price and container size? |
|
🔹 How did their reasoning evolve as they worked through the task? |
|
|
|
💡 **Hints if Needed**: |
|
- Did students start with the given information (e.g., the 24-ounce container costing $3)? |
|
- How did they use this information to reason proportionally? |
|
|
|
✅ **Once you respond, we’ll move on!** |
|

|
### **Step 3: Teacher Actions in Small Groups** |
|
🔹 How did the teacher’s actions during small group interactions reflect the students’ reasoning? |
|
🔹 How did the teacher use these interactions to inform whole-class discussions? |
|
|
|
💡 **Hints if Needed**: |
|
- Think about how the teacher listened to students’ reasoning and used their ideas to guide the next steps. |
|
- What types of questions did the teacher ask? |
|
|
|
✅ **Once you're ready, let’s move forward!** |
|

|
|
|
|
|
🔹 How did the teacher prompt students to initially make sense of the task? |
|
🔹 What role did these prompts play in guiding students’ reasoning? |
|
|
|
💡 **Hints if Needed**: |
|
- Did the teacher ask open-ended questions? |
|
- How did these prompts help students engage with the task? |
|
|
|
✅ **Share your response, and we’ll continue!** |
|

|
|
|
|
|
🔹 What Common Core practice standards do you think the teacher emphasized during the lesson? |
|
🔹 Choose four and explain how you observed these practices in action. |
|
|
|
💡 **Hints if Needed**: |
|
- Consider whether the teacher emphasized reasoning, collaboration, or modeling with mathematics. |
|
- How did the students demonstrate these practices? |
|
|
|
✅ **When you’re ready, let’s move to the final steps!** |
|
|
|

|
|
|
|
|
📝 Based on what you observed, **pose a problem** that encourages students to use visuals and proportional reasoning. |
|
🔹 What real-world context will you use? |
|
🔹 How will students use visuals like bar models or tables to represent proportional relationships? |
|
🔹 Does your problem encourage multiple solution paths? |
|
|
|
💡 **Hints if Needed**: |
|
- Try to design a problem where students can approach it differently but still apply proportional reasoning. |
|
|
|
✅ **Once you've created your problem, let me know!** |
|

### **Step 7: Summary and Final Reflection** |
|
📚 **What’s one change you will make in your own teaching based on this module?** |
|
Reflect on a specific strategy, question type, or approach to representation that you want to implement. |
|
|
|
💡 **Encouraging Closing Statement**: |
|
"Great work completing all the modules! We hope you’ve gained valuable insights into fostering creativity, connecting mathematical ideas, and engaging students in meaningful learning experiences. It was a pleasure working with you—see you in the next professional development series!" 🎉 |
