The subject of a sentence tells us who or what the sentence is about.
The predicate tells us what the subject does or gives more information about the subject.
Example:
The little girl laughed happily.
Subject: The little girl
Predicate: laughed happily
This worksheet is specially designed for Grade 4 students who are learning to build stronger sentence structures. It is also useful for teachers and parents who want to support children in improving their grammar skills at an early stage.
Learning about subjects and predicates is important because it helps students:
Write clear and meaningful sentences
Avoid sentence fragments and errors
Improve reading comprehension
Build a strong foundation for advanced grammar topics in higher classes
The little girl
completed the work
The players
wore a blue dress
The train
The children were noisy
She won the prize
We are late
He runs very fast
They are ready
The subject is the part of the sentence that names the person, place, thing, or idea the sentence is talking about. The predicate is the part that tells what the subject is doing or what is happening. Understanding this difference helps students write complete and meaningful sentences instead of incomplete or confusing ones.
In Grade 4, students move from very simple sentences to more detailed and longer sentences. Learning subject and predicate helps them understand how sentences are built, improves their writing quality, and prepares them for more advanced grammar topics like clauses and complex sentences in higher grades.
Students can find the subject by asking the question “Who?” or “What?” before the verb. The word or group of words that answers this question is usually the subject. Regular practice with worksheets and reading simple passages helps students become confident in identifying subjects.
Students can practice finding predicates by first locating the subject and then asking “What is the subject doing?” or “What is happening?” The part of the sentence that answers these questions is the predicate. Writing their own simple sentences and underlining the action part is also very helpful.
A complete sentence must have both a subject and a predicate to make full sense. Without a subject, we do not know who or what the sentence is about. Without a predicate, we do not know what happens. Learning this concept helps students avoid writing incomplete sentences called fragments.
