Popular Titles at the Book Fair

It is always interesting to me to see which books that kids will purchase at the book fair.  The kids love the erasers, pens and stuff that comes with the book fair but there are always a couple of books that are so popular, I have to reorder many copies for the kids. The most popular ones are usually the ones that are featured in the preview video that I show before the book fair happens.  So far these are the books that are flying off the shelf.
