Iteration and 'Repeat' Loops Quiz for Grade 6

📚 Quick Study Guide

• 🔁 Iteration: Doing something again and again. In coding, it's often called a 'loop'.
• ✨ 'Repeat' Loops: A type of loop that tells a computer to run a block of code multiple times.
• 🔢 Loop Control: Loops continue until a certain condition is met (e.g., repeat 5 times, or until a value is reached).
• 🧱 Block of Code: The set of instructions that the loop executes each time.
• ✅ Benefits: Saves time and code by avoiding repetition of the same instructions.
