For a pirates lapbook we read a Magic Tree House chapter book , Pirates Past Noon by Mary Pope Osborne. Many of the Magic Tree House books have research guides which go along with them--in this case we read Pirates. These guides are packed with lots of neat info and drawings and A17 really enjoys them. Another great book was DK Eye Wonder: Pirate.
The left side of the lapbook contained a minit book on some key vocab from Pirates Past Noon, a list of the books we read, a tabbed minit book on pirates, a minit book on parrots and minit book of A17's favorite pirate jokes.
The right side has an eye spy minit book, a Magic Tree House Passport, a book on words with the letter P , and minit books on island and compass. The MTH Passport includes 4 pages which are used to summarize the book. For compass you might want to try an experiment making your own with a cork, needle and a pan of water. There are several variations of this online.
