- What is a loop in coding?
- A block of code that repeats multiple times
- Why do programmers use loops?
- To repeat the same action many times without writing the code over and over
- What is a 'repeat' loop?
- A loop that runs a set number of times, like 'repeat 5 times'
- In a 'repeat' loop, what controls how many times the code runs?
- A number you choose, like 'repeat 10 times'
- What is a sequence in coding?
- A list of actions done in order, one step after another
- Why does the order of steps matter in a sequence?
- Because the computer does each step in the exact order you write it
- What is a loop condition?
- A question that a loop checks to decide if it should keep running or stop
- What is an infinite loop?
- A loop that never stops running because its condition never becomes false
- In block-based coding, what do loops usually look like?
- Colored blocks that you snap together like puzzle pieces
- What is a loop counter?
- A number that keeps track of how many times a loop has run
- What is Scratch?
- A free block-based coding platform where you create programs by snapping colored blocks together
- In coding, what does 'breaking down a task' mean?
- Splitting a big job into smaller, simpler steps
- What is a nested loop?
- A loop inside another loop, like a loop repeating 3 times with another loop repeating 4 times inside it
- If a 'repeat 5 times' loop contains 3 blocks of code, how many times will the code run total?
- 15 times, because each of the 3 blocks runs 5 times
- What is a 'for' loop?
- A loop that runs a specific number of times, often using a counter that changes each time
