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 lapbook components came from several sources including Homeschoolshare and Hands of a Child. I purchased the lapbook Ahoy Matey! from HOAC. The Magic Tree House items were found on the Random House website which has teacher guides for some of their books.
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.
