This is a Powerpoint lesson going over author's purpose. I covers definitions and examples as well as common question stems on the STAAR test for these types of questions. There's also practice questions at the end to go over with the class with a built in answer key. In my store https://www.teacherspayteachers.com/Store/Staar-Power, you can find a notes for students to fill out as you go through the presentation for their reading notes or notebooks. These is also a quiz in my store to check for mastery. This works great for introducing author's purpose as well as reviewing. Written with STAAR in mind but works with Common Core as well.
