This product is audio, on the chapter book, Music of Dolphins, recorded by my mother, a recently retired elementary teacher who had taught for 35+ years. Her voice is read with expression and is easy for students to listen to. The book is split into 16 different QR codes. Each QR code is labeled with the chapters and the length. This product works well in a listen to reading center in the Daily 5. QR codes are consistently around 8-12 minutes long. This is only audio. I hope you enjoy this product!
