This has been developed to prepare students for standardized testing over the Common Core Standards for fifth grade specifically. The passage comes from http://www.ncsu.edu/project/lancet/fifth.htm and the nonfiction article comes from wikipedia. There are two passages and 13 questions (both multiple choice and short answer). After the questions, there is a writing task broken into three parts. The first part is a short answer where the student must make an inference from the text. The next part, the reader is required to write a brief paragraph explaining an event in the story. Finally, there is a narrative prompt where the students are required to write a page that relates an experience from their life with the story.
You are not paying for the passages, but rather the time and effort it took to create questions, label them with standards, and edit the document for student use.
