As a class we read and discussed "Bob the Alien Discovers the Dewey Decimal System" by Sandy Donovan. By fourth grade the students know how to find books using call numbers but they do not that each number has a meaning. This book is fun for them. While discussing the book, I show students the Dewey Decimal Classification and Relative Index. I turn to random pages and tell them what some of the numbers mean and they always want me to keep going. It's great.
After, I am finally able to use QR codes again. Students worked in groups and scanned a QR code at each of the 10 Dewey sections. The code took them to a website and the groups wrote down topics of books found in that section and then found exact titles to match the topics.
Last, students we discussed what makes them exciting: sounds, tone of voice, content. Each group was assigned a Dewey section and they wrote and recorded a 30 second radio commercial using Garageband. Take a listen.
