In nonfiction writing, a formal tone helps to establish the writer as a trustworthy authority on the subject. In this writing worksheet, Writing With a Formal Tone, students will first review examples of informal language to avoid. Then they will read sentences written with an informal tone before rewriting them using more formal language. Geared toward middle school learners, this activity helps build awareness of variations between standard and formal English, and gives students a chance to practice relating the two.
