3. Appeal to Ignorance A Common Core Lesson By Dean Berry, Ed. D. Gregg Berry, B. A. Common Core Curriculum Solutions

4. Reading with Your Eyes and Your Brain Skillful readers learn how to read persuasive or opinionated text with a very critical eye. They realize that the author’s purpose is to convince the reader to believe what the author is saying and to consider the arguments given as valid even if they violate logical reasoning and lack supporting evidence. The author’s motive may be to get the reader to buy something, vote a certain way, change an attitude, or behave differently.

5. In order to avoid manipulation by the author, good readers learn how to detect poor reasoning and faulty arguments . They are able to identify the various logical fallacies such as begging the question, strawman, overgeneralization, slippery slope, and others. During this lesson, we will study logical fallacies.
