Description
🐞 Debug This! – Loops
Unplugged Coding Debugging Challenges (Grades 4–6)
Help students build real computational thinking skills by finding and fixing errors in looping algorithms — no devices required!
In this unplugged computer science activity, students analyze broken algorithms, identify logic mistakes, and rewrite them so they work correctly. Each challenge focuses on a different type of loop error, helping students understand how repetition works in real-world algorithms.
🔧 What’s Included
✔ 5 Debugging Challenges focused on loops
✔ Student-friendly, real-life scenarios
✔ Clear instructions and structured response space
✔ Complete teacher answer key with:
- Corrected algorithm examples
- Acceptable student variations
- Error type explanations
- Teaching notes and discussion prompts
✔ Standards alignment (CCSS Mathematical Practices)
🧠 Skills Students Practice
- Understanding how loops control repetition
- Identifying common loop logic errors
- Debugging step-by-step algorithms
- Explaining their reasoning using precise language
🏫 Classroom-Friendly Features
✔ Unplugged – no devices required
✔ Easy to use for whole class, small group, or independent work
✔ Great for computer science, STEM, or enrichment
✔ Supports Grades 4–6
📌 Part of the Debug This! Series
This resource is part of the Debug This! unplugged coding series, designed to help students think like programmers by fixing broken algorithms.
👉 Pair with other Debug This! topics such as Basic Algorithms, If / Else, and Boolean Logic for a complete debugging unit.
