In September you estimated 20 cars × 4 riders = about 80 Ferris wheel riders per turn. Now, at 6 turns an hour, how many riders per hour — and what tool did you use that you didn't have in September?

Unit 10 · Lesson 6
Throughout this school year, you have seen math used in many different activities and used it to solve different kinds of problems. Today you look back at the answers you wrote to the questions in Lesson 1-1 — and see how far your math story has come.
Concept Launch
💡 Your math story, one year later
In Lesson 1-1 you estimated riders on a Ferris wheel, decomposed 78.5, and wrote your math story. The question now is not 'what is math?' but 'how have I changed as a doer of math?'
Mathematical Reflection & Portfolio Culmination. 1. Synthesize grade-level mastery across Number Systems, Ratios, Expressions, Geometry, and Statistics. 2. Justify problem-solving strategies using multiple representations (equations, graphs, models). 3. Reflect on mathematical growth and communicate solutions with precision and confidence

Turn & Talk — Launch
In September you estimated 20 cars × 4 riders = about 80 Ferris wheel riders per turn. Now, at 6 turns an hour, how many riders per hour — and what tool did you use that you didn't have in September?
👂 Listen For
A strong answer multiplies 80 × 6 = 480 correctly and names 'rate' as the new tool. A weak answer gives 480 with no explanation of what changed since September.
Extend: The wheel now runs 480 riders an hour. If it operates for 5 hours, how many total riders is that — and how is this calculation an even bigger extension of your September math?

Turn & Talk — Explore
When you sorted skills into 'I could already do this in September' and 'I learned or grew into this during Grade 6,' what made 'dividing a fraction by a fraction' belong in the growth column?
👂 Listen For
Listen for students distinguishing skills that existed before the year started from skills built during Grade 6 — not just listing skills without sorting them.
Extend: Pick one skill from the growth column and explain how it changes the way you would solve a problem from September, like the Ferris wheel estimate.

Real-World Connection
🌍 Math in the Wild
You and your classmates each wrote about your math stories at the beginning of the school year. Everyone has their own math story, and as you encounter new challenges and experiences, your story might change.
✍️ Connection Reasoning
How does your classmate's end-of-school-year math story compare to your story?
Describe how your math story has ___ this year, ask a ___ about their story, and then ___ the two to see how they are alike and different.
Turn & Talk — Connect
In September you decomposed 78.5 as 70 + 8.5. This year you learned 78.5 = 157 ÷ 2 and 50% of 157 = 78.5. How does comparing these show your math story changing?
👂 Listen For
A strong answer names a specific new method (division or percent) and connects it back to 78.5 correctly, not just claiming 'I know more now.'
Extend: Ask a classmate for one new way THEY found to write 78.5. Compare it to yours — what's the same, and what's different about the tools you each used?

🎯 Listen For · Common Errors
• A strong answer multiplies 80 × 6 = 480 correctly and names 'rate' as the new tool. A weak answer gives 480 with no explanation of what changed since September.
• Listen for students distinguishing skills that existed before the year started from skills built during Grade 6 — not just listing skills without sorting them.
• A strong answer names a specific new method (division or percent) and connects it back to 78.5 correctly, not just claiming 'I know more now.'
• Listen for students naming a specific comparison strategy tied to explaining reasoning, not just "I got better."
Common mistake: Treating your math story as finished — writing the same answers you wrote in Lesson 1-1 instead of looking for what actually changed. The story grows and evolves; a retrospective that copies September has missed the point.
Answer Key (Teacher Appendix)
Hide this slide during presentation or move to the end of your copy.
✓ Practice 1: About 480 — 80 riders on each of 6 turns is 80 × 6 = 480 riders per hour — a rate, one of this year's tools.
✓ Practice 2: 78.5 — 50% means half, and 157 ÷ 2 = 78.5 — the very number you decomposed back in Lesson 1-1.
✓ Practice 3: You can explain why a method works, not just follow its steps — Constructing and explaining reasoning is the growth this lesson asks you to look for — it is what makes the math yours.
✓ Practice 4: About 80 — 20 × 4 = 80 — the same estimate you made in September, and it still holds up.
✓ Exit ticket: We are all doers of math in daily life, and our math stories continue to grow and evolve as we grow — The summary makes both claims: everyone is a doer of math in daily life, and our stories keep growing and evolving as we advance.
