This Grade 3 Identifying Subjects and Predicates worksheet helps students clearly understand the two core parts of every complete sentence — the subject and the predicate. Learners practice identifying who or what the sentence is about and what action is happening. Through engaging activities such as underlining, multiple choice questions, sentence completion, fill in the blanks, and paragraph writing, children strengthen sentence structure skills in a practical and age-appropriate way.
Understanding subjects and predicates helps children form clear and complete sentences. This concept is important in Grade 3 because:
1. It teaches students that every complete sentence needs both a subject and a predicate.
2. It improves sentence clarity by identifying who performs the action.
3. It builds stronger reading comprehension skills.
4. It lays the foundation for advanced grammar topics like clauses and sentence expansion.
This worksheet contains five structured grammar exercises that guide students from identification to application:
🧠 Exercise 1 – Underline and Circle
