a chunk of code that repeatedly runs a section of the program a certain number of times

Patterns and repeats

Computing

In this unit pupils will create text-based programs which use repetition. They will plan, modify, and test commands to create shapes and patterns. They will explore the different types of loops that can be used to repeat commands in a program.

Repetition in programs

repeats tasks for a specific number of times

a loop that repeats a task until a condition is met

a loop that repeats a specific number of times

It saves time by avoiding writing the same commands multiple times.

Put these steps in order to use a count-controlled loop:

What command makes the turtle draw a square by repeating a forward movement of 100 steps and turning right?

a precise sequence of steps to solve a task

to complete a task using a set of instructions
