"Punctuation Practice" is a Prestwick House PowerPoint presentation that contains many examples of ways to improve student understanding of punctuation, from the most common issues of end marks to the complexities of comma and semicolon use. There are separate, short exercises for each mark of punctuation and a cumulative set of exercises at the end of the presentation. In addition, we have repeated all exercises, without visible answers, in a PDF format, which can be duplicated and used as worksheets or quizzes. You may also choose which section of the presentation you want to work on by clicking on the slide sorter icon. The examples in each section are the same: an explanation of a common punctuation error followed by exercises that allow students to test their own skills in spotting and correcting the error. The material can be reviewed by the entire class, small groups, or individual students. Slides can also be printed and distributed to students for use as notes, practice, or quizzes.
