Sentence Diagramming 101 One-on-One Instruction


An introduction to the Reed-Kellogg system of diagramming sentences that will increase your understanding of grammar and improve your ability to construct clear, uncluttered sentences. In this eight-week course, you will learn how to diagram various kinds of simple, compound, complex, and compound-complex sentences. A thorough grammar review will also be included.

What people have said about this course:

Not only did I learn to diagram sentences, I was also able to revisit very important rules of grammar and parts of speech. The diagramming was harder than I imagined, but it helped me more than I expected. I liked the interaction from the students’ questions and Denise’s gracious responses to answer what we think we should already know but don’t. —Jenne A.

This is a great class for all editors and writers. It also serves as a great grammar refresher. It definitely covered what I was expecting based on the course name and description. —Mary Anne B.

Thank you for explaining the rough spots on my homework. I’m thankful for a teacher to clarify things for me! —Kristen H.

Instead of being easy, this course was definitely a good challenge. It was very much worth it, mostly because we had to think hard and dig deep. I liked how Denise responded individually to each student about homework assignments and what needed to be changed. —Barbara C.
