Grammar Detective: Identifying Subjects, Predicates, and Objects – Class 4 

This Grade 4 worksheet on Identifying Subjects, Predicates, and Objects helps students clearly understand how sentences are structured. Through underlining, circling, multiple-choice questions, labelled identification, and paragraph-based analysis, learners strengthen their understanding of who or what performs the action (subject), what is said about the subject (predicate), and who or what receives the action (object). The worksheet progresses step-by-step. Students first identify subjects and separate predicates, then circle main objects. They practise selecting correct answers through MCQs, classify labelled parts of sentences, and finally analyse a full paragraph to identify subjects, predicates, and objects in context. This structured approach builds strong grammar clarity and improves writing accuracy.

1. They form the basic structure of every sentence. 
2. They help students understand sentence meaning clearly. 
3. They improve writing accuracy and sentence construction. 
4. They strengthen grammar skills required for exams.
