This warm-up set includes 20 Expository Writing Warm-Ups. It also includes an Expository Explanation page that defines the four Expository Writing tasks as to "Describe," "Explain," "Clarify," and "Evaluate." These are great skills for students to practice leading up to writing their STAAR Expository Writing. Each slide is labeled with the skills that students are practicing regarding that specific prompt.
I usually give my students 3-4 minutes to complete these "quick writes." From that point, I usually model Expository Writing or allow students to return to their writing at a later time and apply a new writing skill.
