Coding Loops: Repeating Actions in Scratch

A loop is a block in Scratch that makes the computer repeat an action more than once without writing the same block many times. Instead of stacking "move 10 steps" ten separate times, you place one "move 10 steps" block inside a "repeat 10" loop. This saves time, makes code shorter, and is easier to read.

1Explain what a loop is and why programmers use them
2Identify the "repeat X times" block in Scratch and describe what it does
