The first book is How I Became a Pirate by Melinda Long and David Shannon (author of the "David" book series). My son loves this book and its fun to read out loud. I love kid's books where kid's can imagine themselves in the story and this one fits the bill. The kids enjoyed it.
I also read Pirate Pete by Kim Kennedy. My son loves this book, but its a bit long in my opinion (and repetitive, not in a good way). The kids enjoyed it but they were definitely getting antsy by the end of the story, so it was craft time immediately after.
I did something a little different this week, and we did a group craft. We built pirate ship by Alex's Toys. Each of the kids decorated part of the ship and then we put it together (using tape instead of glue). It was fun and it now lives at the bookstore for everyone to enjoy.
