📚 Topic Summary
Unplugged activities are a fantastic way to learn computer science concepts without needing a computer! The Sorting Game is an unplugged activity that helps you understand how sorting algorithms work. These algorithms are step-by-step instructions computers use to arrange items in a specific order, like putting numbers from smallest to largest or arranging names alphabetically. By physically sorting objects, you experience the logic and efficiency (or inefficiency!) of different sorting methods firsthand.
In this activity, you'll use things like playing cards or even yourselves to act out the steps of simple sorting algorithms. This hands-on approach makes abstract ideas more concrete and easier to grasp. Plus, it’s a great way to collaborate and problem-solve with others!

✏️ Part B: Fill in the Blanks
Fill in the missing words in the paragraph below.
A _______ algorithm is a series of steps that _______ data. In a _______ sort, you repeatedly step through the list, compare adjacent elements and _______ them if they are in the wrong order. This process is called _______. The goal is to arrange data in ascending or _______ order.

Answer: A sorting algorithm is a series of steps that sorts data. In a bubble sort, you repeatedly step through the list, compare adjacent elements and swap them if they are in the wrong order. This process is called iteration. The goal is to arrange data in ascending or descending order.
🤔 Part C: Critical Thinking
Imagine you have a deck of cards that needs to be sorted from Ace to King. Describe how you would explain the process of sorting to someone who has never sorted cards before. What specific steps would you tell them to follow?
