The dozen activities in this book don't require a computer, but will help readers become masters at computational thinking. This volume stars out with activities highlighting the necessity of giving clear, direct instructions. It continues to include instructions that introduce readers to concept of computer languages, commenting on codes, number systems, and the importance of binary in coding. Fun illustrations and informative sidebars help make the volume engaging, while back matter elements like a glossary and further reading section reinforce what readers have learned and offer ways to learn more about thinking like a coder.
