Let’s Celebrate St. Patrick’s Day [PDF ebook] 

In a question and answer format, this book gives a history of this holiday from it’s beginnings all the way up to how it is celebrated around the world today. Interspersed are fun facts and riddles. At the end of the book readers are invited to make a St. Patrick’s Day banquet with a special shamrock cake (enough to feed a classroom) and other green goodies.
