Scratch 1.4: Beginner's Guide

Overview of this book

If you have the imaginative power to design complex multimedia projects but can't adapt to programming languages, then Scratch 1.4: Beginner's Guide is the book for you. Imagine how good you'll feel when you drag-and-drop your way to interactive games, stories, graphic artwork, computer animations, and much more using Scratch even if you have never programmed before. This book provides teachers, parents, and new programmers with a guided tour of Scratch's features by creating projects that can be shared, remixed, and improved upon in your own lesson plans. Soon you will be creating games, stories, and animations by snapping blocks of "code" together. When you program you solve problems. In order to solve problems, you think, take action, and reflect upon your efforts. Scratch teaches you to program using a fun, accessible environment that's as easy as dragging and dropping blocks from one part of the screen to another. In this book you will program games, stories, and animations using hands-on examples that get you thinking and tinkering. For each project, you start with a series of steps to build something. Then you pause to put our actions into context so that you can relate our code to the actions on Scratch's stage. Throughout each chapter, you'll encounter challenges that encourage you to experiment and learn. One of the things you're really going to love is that, as you begin working through the examples in the book, you won't be able to stop your imagination and the ideas will stream as fast as you can think of them. Write them down. You'll quickly realize there are a lot of young minds in your home, classroom, or community group that could benefit from Scratch's friendly face. Teach them, please.

Summary


Not only did we use math to solve our question, but we also learned that doubling is a very powerful concept when applied over time. Double my money, please!

With the exception of the pen tool and the mathematical functions, this chapter built on many of the concepts we've learned before. Specifically, we relied heavily on the use of variables to provide an interactive project that is capable of crunching a wide range of number combinations.

This chapter introduced mathematical functions and the pen tool to help us play out the action on the stage. We used math to solve three types of problems in our program. First, we solved the equations. Second, we used math as a conditional check to determine if we needed to double our amount one more time. Third, we used a trigonometric function to graph the results of the double equation in a way that scaled to the Scratch stage.

Much like in daily life, we can't escape math as Scratch programmers. This knowledge is worth accumulating and, once...
