Coding — If & Then — Part 1 Learn the concept, study the code, then try the challenge! 💻 Coding Concepts Coding means writing instructions that a computer can follow step by step. Code Example: // Every program has: // 1. Input — data going in // 2. Process — what to do with it // 3. Output — the result Steps: 1. Understand the problem 2. Plan your solution (algorithm) 3. Write the code 4. Test your code 5. Debug and improve 🚀 Try It! Write step-by-step instructions to make a peanut butter sandwich. Be specific! 🐛 Debug Challenge: Your instructions say 'put peanut butter on bread' but the robot puts the jar on the bread! Rewrite more clearly. My Fix: www.littleactivity.com 1st Grade — Page 1
