This document provides a lesson on sentence structure and parts of a sentence for a 7th grade Puerto Rican folktales class. It defines a sentence as a group of words with a subject and predicate, beginning with a capital letter and ending with punctuation. The subject is defined as the who or what of the sentence, and the predicate tells what the subject does or is. Examples are provided and students are directed to an online form to practice identifying sentences and do their homework.
