Bug Examples in Scratch for Elementary Students

📚 Quick Study Guide

• 🐛 A bug is an error in your code that makes it not work as expected.
• 🐞 Common Scratch bugs include incorrect logic, wrong variable values, and infinite loops.
• 💡 Debugging means finding and fixing these bugs.
• 🔍 Use the 'step-by-step' execution to see how your code runs.
• 📝 Check your scripts carefully for mistakes in blocks or values.
• 🛠️ Try adding 'say' blocks to display variable values and understand your code's behavior.
