Mission: Pattern Detective — Level 3
Akuuu is building a fence for her garden. She places posts in a row: wood, metal, wood, metal, wood…
Her friend Lina says the next post should be wood. But another friend says it should be metal.
👉 Who is correct? How do you know for sure?
Think: What is repeating? Can you predict what comes next?
✏️ Draw the pattern or write your answer:
- 🔁 A pattern repeats in a predictable way
- 🔍 The core unit is the smallest repeating part (here: wood + metal)
- ➡️ To continue a pattern, repeat the core unit in order
Look at this pattern: 🔺, 🔺, ⭐, 🔺, 🔺, ⭐, 🔺, 🔺…
👉 What comes next? What is the core unit?
👉 How is this pattern different from “wood, metal, wood, metal”?
2, 4, 6, 8, ❓, ❓
👉 What are the next two numbers? What is the rule?
A child writes this pattern: 5, 10, 15, 20, 25, 31, 35
👉 Where did the pattern break? What should the number be?
Make a pattern with a core unit of 3 items. Write the first 6 items.
👉 Explain your rule so a friend could continue it.
🧠 Part A — Transfer
Akuuu sees this pattern in nature: flower, leaf, leaf, flower, leaf, leaf, flower…
👉 Is this the same kind of pattern as “wood, metal”? Explain why or why not.
Think: Compare the core units. Are they the same size? Does the same idea still work?
🧠 Part B — Thinking Pause
- I explained why the pattern works
- I found the mistake in the broken pattern
- I showed another way to describe the rule
