Understanding Basic Loop Concepts

What is a loop in computer programming?

• A way to store data

• A sequence of instructions that repeats until a condition is met

• A type of variable

• A way to display output

Which block is commonly used to repeat a set of instructions a specific number of times in code.org?

• "If" block

• "Repeat" block

• "Variable" block

• "Function" block

What does the number in a "repeat" block represent?

• The number of variables

• The number of times the loop will run

• The number of functions

• The number of outputs

If you want BB-8 to move forward 5 times, which loop block would you use?

• Repeat 5 times

• Repeat 1 time

• Repeat 10 times

• Repeat 0 times

What is the main advantage of using loops in programming?

• They make the code longer

• They help repeat actions without writing the same code many times

• They make the code harder to read

• They slow down the program

Which of the following is an example of a loop in everyday life?

• Reading a book once

• Brushing your teeth every morning for a week

• Writing your name one time

• Eating lunch once

If Rey wants to collect 3 parts, and each part is collected by moving forward and picking it up, how many times should she repeat the move and pick up actions?

• 1

• 2

• 3

• 4

You have the following instructions: "Move forward, turn left, move forward, turn left, move forward, turn left, move forward, turn left." How can you use a loop to simplify these instructions?

• Repeat 2 times: Move forward, turn left

• Repeat 4 times: Move forward, turn left

• Repeat 8 times: Move forward, turn left

• Repeat 3 times: Move forward, turn left

If a loop repeats 6 times, and inside the loop BB-8 moves forward 1 space each time, how many spaces will BB-8 move in total?

• 3

• 6

• 12

• 1

Which of the following tasks would be best solved using a loop?

• Drawing a single line

• Moving forward once

• Collecting 10 items in a row

• Turning left one time
