Multiple Choice Questions on Debugging in Scratch for Elementary Students

📚 Quick Study Guide

🔍 Debugging: Finding and fixing errors (bugs) in your code. 💡 Common Scratch Bugs: Scripts not running, sprites not moving as expected, incorrect calculations. 🛠️ Debugging Tools: Using the 'stop sign' to halt scripts, stepping through code slowly, using 'say' blocks to check variable values. 🐛 Testing: Trying different inputs and scenarios to find bugs. 📝 Reading Error Messages: Scratch doesn't always give clear errors, but look for unexpected behavior. ➕ Simplifying: Break down complex scripts into smaller parts to find the problem. 🚀 Asking for Help: Sometimes another pair of eyes can spot the bug!
