๐ Topic Summary
A 'for loop' is a way to repeat a set of instructions a specific number of times. Think of it like following a recipe where you need to repeat a step multiple times. Instead of writing the same step over and over again, you use a for loop to tell the computer (or yourself!) to do it the required number of times. Unplugged activities use real-world scenarios to understand this without needing a computer.
The core idea is that the loop continues as long as a certain condition is true. Once the condition becomes false, the loop stops. This worksheet lets you practice these ideas in a hands-on way.

D. A named storage location in a computer's memory that can hold a value. |
| 5. Increment |
E. To increase a variable's value by a certain amount. |
๐ Part B: Fill in the Blanks
A ______ is a programming structure that repeats a block of code. Each time the code is executed, it is called an ________. The loop continues as long as the ______ is true. A common practice involves using a _______ to keep track of the number of times a loop has run. Often, this variable is ________ each time the loop executes.
๐ค Part C: Critical Thinking
Imagine you need to plant 10 trees in a row. How would you describe this process using the concept of a 'for loop' without using a computer? Explain the steps involved and what condition would stop you from planting more trees.
