๐ Topic Summary
In Scratch, variables are like containers that hold information (numbers, words, etc.) that can change as your program runs. Think of it as a score in a game that increases as you play! Loops, on the other hand, are used to repeat a set of instructions multiple times. Imagine making a character walk across the screen by repeating the 'move' command many times. Combining variables and loops allows you to create interactive stories, games, and animations where things change and repeat dynamically.
This worksheet will help you understand how to use variables and loops together in Scratch. Get ready to create amazing projects!

๐ค Part C: Critical Thinking
Describe a simple game you could create in Scratch that uses both variables and loops. Explain how each is used in your game.
- ๐ก Consider a game where the player earns points (variable) for each successful action, and the game repeats (loop) until a certain score is reached or time runs out.
