For many years, my classes have enjoyed Absent Author by Ron Roy. While reading, we try to investigate just like Dink, Josh and Ruth Rose. We talk about the elements of a mystery and then identify the mystery and clues using the detective booklet.
I have vocabulary practice, a map of Green Lawn to make, an 8 page detective booklet and a book test included with this unit. I also have included a short game to play after the chapters that were read and an end of the book game.
I use the map for retelling and sequencing. The 8 page booklet is to track the detectives, persons of interest - supporting characters, suspects, crime and clues page and a page to wrap up the mystery. Posters are included explaining the elements of a mystery as can be applied to this book. The test has some comprehension questions, vocabulary and a character motive section.
I do not use this book for a lot of comprehension practice but rather a study of story elements and mysteries.
