๐ Topic Summary
Unplugged activities for teaching function parameters involve simulating computer programs and functions using non-digital tools. The core idea is to demonstrate how functions receive inputs (parameters), process them, and potentially return an output. Students can act as functions, manipulating physical objects based on provided instructions, thereby grasping the concept of passing data to functions and obtaining results without writing actual code. This hands-on approach makes the abstract concept of function parameters more concrete and understandable.

โ๏ธ Part B: Fill in the Blanks
Fill in the missing words in the paragraph below:
A _________ is a block of code that performs a specific task. When you call a function, you can pass in _________ which are used as inputs within the function. These inputs are also called _________ inside the function's scope. After processing, a function can send back a _________.
Answers: Function, parameters, arguments, return value
๐ค Part C: Critical Thinking
Imagine you're writing instructions for making a sandwich. How would you describe the function 'makeSandwich' and what parameters would it need?
