Often students assume that "nonfiction" means all facts. We all know that isn't always the case. Commonly opinions are stuck inbetween the facts. This worksheet explains the difference in fact and opinion and addresses bias. I use a nonfiction text from the text book named "Emancipation" to have students evaluate fact and opinion in a nonfiction text. This document is easily editable to change to use with any nonfiction text you are interested in using.
