π Topic Summary
Unplugged activities for teaching 'else' logic involve simulating conditional statements without writing any code. This helps students understand the concept of 'if this, then that; else, do something else' in a tangible and engaging way. We can use everyday scenarios, flowcharts, or even physical actions to demonstrate how 'else' logic works, making it accessible to beginners.

π Part B: Fill in the Blanks
In an 'if...else' statement, the '_____' part allows you to specify a block of code that should be executed only when the initial _____ is _____. If the condition is _____, the 'else' block is skipped, and the program continues with the next instruction after the 'if...else' structure. Understanding this is key to writing programs that can handle different _____ based on specific criteria.
(Answers: else, condition, false, true, scenarios)
π€ Part C: Critical Thinking
Describe a real-life scenario where you use 'if...else' logic to make a decision. Explain the condition, what happens if the condition is true, and what happens if the condition is false. How does understanding 'else' logic help you in everyday situations?
