Lesson Three

Creating Shapes

In this lesson we are going to be using the ‘pen’ control to create different shapes. We will start with more simple shapes and move on to create more complex shapes and patterns.

Set your sprite to the character of your choice. This could be one from the gallery in ‘Scratch’ or you could draw your own using the paint toolbar.

Lesson Three

Create the following script for your sprite. You will find the ‘pen’ controls in the ‘pen’ tab in the top left hand corner.

Can you guess at which shape will be made before you click on the ‘start’ icon?

Lesson Three

Can you alter the previous script so that you will create a rectangle?

We are now going to create a slightly more complex shape. Copy the following script for your sprite:

Can you guess the shape that the sprite will make before you click on the ‘start’ icon?

Lesson Three

Alter the previous script so that it looks like the one below. What do you notice?

Lesson Three

Your sprite should make the following pattern when you click on the ‘start’ icon.

Can you make anymore patterns using squares and rectangles? Try changing the colour of the pen to create different effects.

Lesson Three

Create the following script for your sprite. We are going to make an octagon using scratch.

Before you click on the ‘start’ icon, you will need to change how many degrees the sprite needs to turn in order to create an octagon. Remember, an octagon has 8 sides.

Can you now add the ‘forever’ icon to create a pattern?

Lesson Three

Try to create the following shapes:

• Equilateral Triangle• Dodecahedron (12 sides)

• Heptagon• Pentagon• Circle

Extension Activity

Create different complex patterns using two or more shapes and repeating sequences.
