This document provides an overview of subject, predicate, and object for a 7th grade grammar unit. It defines the subject as the noun doing the action, the predicate as the verb or action, and the object as the noun receiving the action. Examples are given for each. The document then practices identifying these parts in sample sentences and distinguishes between direct and indirect objects. It provides multiple practice problems for students to identify the subject, predicate, and object(s) in various sentences.
