We started off the lesson by reviewing the characteristics of fiction and nonfiction books by filling in a T-Chart. I also had an example book for each to show the kids. I used fiction Froggy book and a nonfiction book about frogs. We looked at those books, but we talked about the in general characteristics of these genres of books and not specifics of the 2 example books.
After we reviewed the characteristics and filled in our T-Chart, I had pairs of fiction and nonfiction books on all the tables. I literally just pulled 24 books off the cart and typed the titles of the books into this Fiction or Nonfiction Activity Page (which is also where the T-Chart is).
I gave the teachers the answer key and this activity was for a grade. The kids did a great job with this activity!
