One of the basic rules of commas is that they are similar to pauses that occur in speech. This is what this worksheet practices. The basic rules of commas will have to be reviewed before the page can be issued, but when it is in use, you will find this resource effective for student use. Change up the examples for a particular class's needs, or just add some more for increased challenge.  This can be used as a quiz, homework, or for group work.
