Lesson 4.4: Drawing in Scratch, Complex Shapes

Learning Objectives:
Students will learn how to draw more complex shapes in Scratch, such as a flower consisting of several petals, spinning squares, or stars.
  • Students will learn how to vary the code in Scratch to add creative elements.

Activity Part 1: Basic Flowers

*Note: your colors may be different depending on what color your pen was set to before drawing the flower, so do not worry about colors at all

TRY THIS: MAKE YOUR OWN FLOWER

Based off of the flower example above, try to vary the code or add your own twist to create a more fun and unique flower.
Here is what we did as an example:





Activity 2: Draw Your Own Complex Shape
Try creating your own image (it could be a complex shape, flower, spiral, pattern) using various colors and pen sizes! Look below for Inspiration!

Here are some sample images we have created -- try recreating it yourself and playing around with the various components for more practice.

POINTY DISK


OCTAGONAL SPIRAL

MULTI-COLORED LOOPS


Lesson 4.4 Wrap Up:
SPIRAL MAKER

Try out this program made by the Scratch Team, called Spiral Maker.

This example is particularly interesting because it defines a function, called spiral, which draws a multicolored spiral. The program is also neat because the origin of the spiral is where you specify through your mouse. While the program may seem complex, the code is fairly simple to follow. First, play around with the code to adjust some of the features and second, make your own shape maker. 

Based off this example, we made a simple star maker. Check it our here!
