Fact Checking Sites

     Download a pdf version of this poster HERE. There's an interesting site where you can read an online book titled Web Literacy for Student Fact-Checkers...and other people who care about facts. The book covers a wide range of techniques and tips for fact checking things you read on the web to determine if they are accurate. There is also a table of contents that outlines the topics included in each chapter. The “book” does contain spelling errors, but it's still worth a read.
