The new teachers' edition collects 12 of the 20 original activities, revised and extended by Robyn Adams and Jane McKenzie to better suit elementary-aged children. It also includes advice for integrating Unplugged activities into primary school curricula. Additionally, the book has been re-typeset, and many new illustrations have been added.
