This book will familiarize you with the Scratch visual programming environment, focusing on using Scratch to learn computer science. The book is structured as a collection of tasks. Each chapter teaches a new concept, but the concept is introduced in order to solve a specific task such as animating dancing images or building a game. Each chapter starts with a simple task, but as soon as we solve one task, we add additional tasks to extend the existing task. The sequence of tasks will require a new construct of Scratch or the use of constructs you know in new ways.<\/p>\n

The textbook was written for Scratch 1.4. We have also written a supplement that explains the changes and additional features in Scratch 2.0.<\/p>\n

The textbook is available in three formats:<\/p>\n

    \n
  1. with equal margins for screen display and one-sided printing;<\/li>\n
  2. with margins for two-sided printing and binding in the left margin;<\/li>\n
  3. with a large font on a small text area that enables better accessibility by magnifying the pdf.<\/li>\n<\/ol>\n

    The layout was carefully done for the full-size pages and will be suboptimal in the small format; we have no plans at this time to improve this format or to produce other formats for ereaders.<\/p>\n
