Subjects Predicates Sentences Practice Activities
Grade 4 grammar worksheets help students identify subjects, predicates, and complete sentences with clear, printable practice.
Practice that builds confidence
Building the idea of a complete sentence
These Grade 4 Grammar and Writing worksheets focus on how sentences work: who or what the sentence is about, and what that subject does or is. Children practise finding the subject and predicate, noticing complete thoughts, and separating sentence parts accurately.
The printable activities include sentence marking, sorting, completing, and editing tasks. Students work with full sentences rather than isolated words, so they build grammar understanding that supports clearer writing.
A complete sentence needs both a subject and a predicate. In Grade 4, students move beyond naming nouns and verbs to seeing how the two parts fit together. In a sentence such as “The noisy puppy chased the red ball,” the complete subject is “The noisy puppy,” while the complete predicate is “chased the red ball.” The worksheets give repeated practice with this sentence-level thinking.
What students practise on the page
Activities may ask children to underline subjects, circle predicates, match sentence parts, or decide whether a group of words is a complete sentence. Some items use simple subjects and simple predicates, while others include longer phrases so students learn not to stop too early. This helps them see that a subject can be more than one word and that a predicate can include objects, adverbs, or other details.
A parent routine that works
At home, choose three sentences from a book, article, or homework reading. Ask your child, “Who or what is this sentence mainly about?” Then ask, “What is being said about it?” Have your child draw a vertical line between the complete subject and complete predicate. After one example together, let your child try two independently and explain the choice aloud.
Classroom uses for teachers
Teachers can use these printables for grammar mini-lessons, morning work, writing centers, or quick checks before a paragraph-writing task. The worksheets also pair well with revising: students can return to their own drafts and check whether each sentence has a clear subject and a complete predicate.
Common errors to watch for
Many Grade 4 students circle only the noun as the subject, even when words before it belong to the complete subject. Others identify only the verb as the predicate and leave out the rest of the action or description. Watch for fragments, too, such as “After the storm” or “The children in the hallway,” which may sound meaningful but do not express a complete thought.

Why iBloom worksheets help
These iBloom worksheets keep the focus on real sentence structure instead of memorized labels. Clear directions, varied sentence patterns, and printable space for marking help students slow down, test their answers, and build a reliable strategy: find the main “who or what,” then find everything the sentence says about it.
Helpful answers
Frequently asked questions
What do Grade 4 students learn in subjects and predicates practice?
They learn to identify who or what a sentence is about, what is being said about that subject, and whether the words form a complete sentence.
Should my child find the simple subject or the complete subject?
Both are useful, but these worksheets help students notice the complete subject and complete predicate so they understand the full structure of the sentence.
How can I help if my child confuses the predicate with just the verb?
Ask, “What is the subject doing or being, and what words complete that idea?” This encourages your child to include the whole predicate, not only the action word.
Are these worksheets useful for improving writing?
Yes. When students can spot missing subjects or incomplete predicates, they are better able to revise fragments and write clearer sentences.
Can teachers use these activities for small groups?
Yes. The printables work well for small-group reteaching, grammar centers, warm-ups, or quick checks before students write paragraphs.
