Breaking Down Problems in Computer Science [PDF ebook] 

In computer science, understanding problems and systems can be difficult and time consuming. In this book, readers will learn about decomposition, a technique used to break down computer problems and systems into parts that are easier to understand and work with. STEM topics from the Next Generation Science Standards are discussed throughout this informative text. Students will be surprised to learn they actually decompose problems in their daily lives without even realizing it.
