Each book introduces a new fundamental
computer science concept, with subsequent books
spiraling back to previously-seen concepts and
coding commands. Each set of books includes a
unit-specific Educator's Guide with line-by-line
code explanations, challenge solutions, and journaling
suggestions for each app project.
Unit 2: Variables & Simple Methods introduces
the use of placeholders for values and
making code easier to change. The apps in Unit 2
illustrate the use of variables to
store numbers, strings, booleans, and Bitsbox
stamp objects. These projects also introduce the
Bitsbox move, rotate, and size commands.
This book includes 10 open-ended projects,
divided into 3 project types:
How Do I? Apps
These examples answer common student questions
about coding their own apps.
- Invaders From Space | 4 lines of code
How do I move stamps to different places?
- Black Hole Blues | 5 lines of code
How do I make a stamp disappear into a black hole?
- The Lonesome Yeti | 6 lines of code
How do I make a stamp appear on the
bottom half of the screen at a random size?
These examples provide the code
needed to build each app, along with challenges
that enhance their understanding of the material.
- Getting Started Mini Apps | 3 + 4 + 3 lines of code
These three super-short examples lay out the basics
of using the text, .move, .rotate, and .size commands.
- Mars Needs Milk | 14 lines of code in 2 code sections
Tap tap tap to suck cows into your flying saucer!
- Bedbug Bedlam | 12 lines of code in 1 code section
Pop the never-ending bedbugs before they take over!
- Burnie the Artbot | 12 lines of code in 1 code section
Draw with Burnie's super hot laser!
- Castle Defender | 15 lines of code in 3 code sections
Create a castle to defend from the evil robot.
No code provided! These examples challenge
students to code an app based only on an image
and a description of the final product.
- Draw with Droids | 6 lines of code (as assigned)
Haven't you always wanted to paint a masterpiece with tiny bots?
- Welcome to the Wormhole | 11 lines of code (as assigned)
