Mysteries from history

I really like this series by Jane Yolen. Each book is a different unsolved mystery from history. The text features she uses are really unique. This is a picture of the bulletin board I made after reading The Mary Celeste (my favorite of the 4) with my class.You can see she uses "stickies" to define words the kids might not know (in this book the words were about sailing). She has another box with background information for the reader. I haven't found a lot of picture books that are mysteries. This series inspired some of my readers to look for paperback mysteries. One thing the kids didn't really like was that these historical mysteries were never solved. At the end of the book,  the author encourages kids to use critical thinking skills to come to their own conclusions. Christine
