This e-book is one complete writing unit which includes 28 opinion and informative (expository) writing lessons. There are two performance-based assessments that include student supports and student-friendly rubrics. The lessons follow and expound upon the ideas in Grade 4 ReadyGEN, but may be used independently, or with another program. Each lesson in this unit provides many teaching and learning supports such as color-coded models, graphic organizers with answer keys, sentence and paragraph frames for SEI, ELL students, linking words and phrases, and clear, step-by-step instructions for creating opinions and informative or expository essays. With this book, teachers can teach exactly how to compose coherent writing, and students can succeed because they will know exactly what is expected of them. P.S. I wrote Unit 3 first because I was teaching it at the time of writing it. Unit 1 is coming soon!
