Today you are coding in Scratch. You will build a Pattern Creator step by step at your device. You can already make a sprite move and turn. Today you will put those actions inside a loop so the pen draws circles, lines and spirals without copying the same blocks over and over. Before you run anything, think: what might happen if the sprite keeps moving and turning a little bit each time?

Welcome to our exciting lesson on Pattern Creation! In this lesson, you will learn how to create cool patterns using Scratch. You will learn how to code the pen tool and use variables to make your patterns more interesting. By the end of this lesson, you will be able to create your own unique patterns. So, let's get started!

Go to the Scratch website, create a new project and delete the cat sprite. scratch.mit.edu/projects/editor

We are going to use the Pen blocks to create patterns but first we'll need to add a sprite that will do the drawing. It doesn't really matter which sprite we use as we are going to hide it. Add the Ball sprite from the sprite library and then give it the following code. when green flag clicked go to x (0) y (0) // we want to start it in the center hide

To draw the patterns we will be using the Pen blocks so add the Pen Extension to your project. Once you've added the Pen Extension add the following new code blocks to the Ball sprite underneath the hide block. when green flag clicked go to x (0) y (0) hide // add new code under here pen up // start with the pen up erase all // erase drawings from the last time set pen color to [#3438df] // choose a color pen down // put the pen down
