Olivia Brophie and the Pearl of Tagelus written by Christopher Tozier is an excellent children's book, and a great read aloud for younger grades. It is loaded with rich vocabulary. This activity covers the vocabulary from chapters 11-22. It is a QR Code matching activity, and included in the download are the QR codes, an answer key to be used at your discretion, recording documents, and an extension activity.
This would be great to use during the last chapters of the book, or as a front loading activity.
