We do this the day before Thanksgiving break. Everyone brings a book to the "feast" (from home, or from the classroom or school library) to share with their friends.
This can be done in lots of ways: students can do a "book talk" to the whole class or a small group, make a commercial for their book, or simply meet in table groups to trade and share their books. We eat Bugles and fruit snacks (to look like cornucopias) while we read and chat!
This is a great way to expose kids to a variety of books they may not have chosen themselves, and a low-prep activity for that last day before Thanksgiving weekend!
