Scratch Practice Exercises

Practice Exercise #1:
The purpose of this assignment is to familiarize you with the Scratch
programming environment by creating a simple animated story similar to the
cat and dog story.
For your animated story, be creative and have some fun! You can implement
any action or any story with any characters that you find interesting. I expect
that you will use the broadcast and When I receive blocks to activate scripts
across sprites. Remember to use good names for the broadcast and receive
messages!
At a minimum, I expect that your animated story will include:
•

•
•
•

At least two Sprites. You may either draw your own Sprites, use some of
the existing Sprites included with Scratch, or import your own images (in
.jpg or .gif format) to make Sprites
Each Sprite should contain at least three scripts
The scripts should use a variety of blocks from at least the Motion, Looks
and Sounds categories
Add a background other than white!

In your story, you may not use existing code that you find elsewhere, including
the Scratch website. You may look at the behavior of existing Scratch projects
for inspiration, but you should develop all of your code as a completely new
project and not modify, re-mix, or build from anyone else's code.
