The Grade 5 Informational Text Reading Inventory (ITRI) was developed to address the specific reading challenges that grade 5 students encounter when reading their textbooks and other informational text. In fifth grade, students are expected not only to comprehend difficult passages, but also to extend their comprehension through drawing inferences and critically evaluating the materials they read. This booklet contains all the information teachers need to use the Grade 5 ITRI materials, including assessments, lessons, concluding projects, answer keys, student scoring sheets, and a survey of the scientifically-based reading research that is foundational to ITRI. Because all Grade 5 ITRI content comes from "Indiana's Standards" for grade 5, the ITRI materials will enhance the subject matter teachers already teach. Students learn the reading skills within the context of their content area curriculum. Appended are: (1) The Scientifically-Based Reading Research (SBRR) Behind Grade 5 ITRI; (2) Chart of Academic Standards Addressed Across the Curriculum; (3) Scoring Sheet: ITRI Assessments; (4) Scoring Sheet: Grade 5 ITRI Lessons; (5) Preparing Students for Research Projects; and (6) ITRI Acknowledgments. A glossary is included.
