A new course is being added in some schools to combat the rise of "fake news".

FOX's Tonya J. Powers has more:

Readin', writin', rithmetic and fake news? That's the latest addition teachers are making to some classrooms, elementary through college.

They're telling students how to distinguish between factual and fictional news and why they should care if there's a difference.

Last month, a California lawmaker introduced a bill to require the state to add lessons on how to tell between real and fake news to the curriculum in grades seven through 12.

It comes at a time when Facebook is working with the Associated Press, Factcheck.org and other organizations to curb the spread of fake and misleading news on its network.

Lessons include checking the URL carefully and looking for incorrect grammar and writing.
