These books would be a great and wide selection of stories for second grade teachers to keep in their classrooms. They are great for introducing chapter books into students' lives, the vocabulary used in the stories isn't difficult for most children to understand, and each book involves a lot of fun and exciting adventures! I read many of these books growing up and I think the reason I loved them so much is because of the exotic and new places the main characters traveled in each story. Having the same main characters in each book made me as a reader feel connected, but the adventures made the stories intriguing and new each time. These books could be used for many different options in literacy centers. Selecting unfamiliar words from the text, pretending to be the author and changing a major point of the story, or illustrating different parts of the story themselves are just a few ideas that can be used!
