Just like a haunted house, coding can be a scary thing to explore. But unplugged coding can make it fun! In the hands-on activities in this book, readers will use problem-solving to construct a tower to search for UFOs and use loops to rid a haunted house of ghosts. Introductory text explains each coding concept, while follow-ups after each activity encourage the reader to think through the results and consider what could be done better.
