This document has been developed to prepare students for standardized testing over the Common Core Standards in English (grammar and writing) for fifth grade specifically. The passage is from the Texas STARR released items for 4th grade (2011) and from a website. There are 15 questions related to grammar, vocabulary, and sentence structure. In addition, there are 3 short answer questions and an extended response prompt.
You are not paying for the content, but rather the time and effort it took to create questions, label them with standards, and compile and edit the document for student use.
