Using the pen in Scratch

Using the pen requires a lot of thought

Using the pen in Scratch requires us to set a specific set of instructions for the computer to follow.
If one of the instructions is not correct, the shape that comes out will not be correct.
A lot of the time, using the pen will require a lot of trial and error.

Plugins

A plugin is a special piece of code that extends the functionality of an existing program.
The pen tool is a Scratch plugin that you will need to add at the start.
