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!" |
|
|
|
Video: |
|
"Watch the video provided at this link. Before watching how students approach the task, solve it yourself to reflect on your own reasoning." |
|
|
|
Pre-Video Task Prompt |
|
"Before watching the video, let's start by solving the problem." |
|
|
|
1. 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!" |
|

|
Step 4: Initial Prompts and Sense-Making |
|
- "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!" |
|

|
Step 5: Common Core Practice Standards |
|
- "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!" |
|
|

|
Step 6: Problem Posing Activity |
|
"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!" |
