This book is a great way to show students what cause and effect is. Jeremy Jacob, the main character, joins a pirate crew and learns lots of exciting things about a pirate's adventurous life, but then learns that being a pirate is not always fun. There are many things he begins to miss. Using a graphic organizer, I would teach my second graders what the cause and effect of the story is. I also found a package of activities you could purchase for this book.

Also, this would be a very fun theme to have!
