Grammar Bytes at ChompChomp.com offers grammar exercises on topics such as commas, irregular verbs, and misplaced and dangling modifiers. Other topics covered in these exercises include parallel structure, pronoun agreement and word choice. Most exercises include fill-in-the-blank and short-answer questions, and have accompanying handouts that instructors can download to give to students.
Grammar Bytes also offers a glossary of about 100 commonly used grammar terms. Some entries link to YouTube videos that explain the terms in addition to the written definitions. The site also provides links to presentation materials that teachers can download and use in the classroom. There is also a Tips and Rules link, which provides brief descriptions of the rules and topics covered in the handouts and exercises offered by the site. Another featured resource is the Kirkman Reader, described as a "dynamic, crowdsourced collection of essays and videos" and recommended for use in college writing courses. These readings and videos are intended to serve as prompts for essay writing and class discussions.
The site also offers a free accompanying Massive Online Open Course, which is open to anyone. Students can enroll to study grammar lessons and take quizzes, which are graded and tracked as the student completes the course.
