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
