Commas is one of the first books in the new "Teaching the Boring Stuff" series. With short, easy-to-digest activities that have a sense of humor, students learn to use commas correctly. At the same time they also learn a great deal about sentence structure. Commas presents material in an interesting way, using language that makes sense to kids. Best of all, it has students using what they learn - and helps them perform better on assessment tests as well.
