The Missing Who

The Missing Who helps students repair sentence fragments that are incomplete because they do not name who or what performs the action. Students read each predicate, choose an appropriate subject, and rewrite the idea as a complete sentence that makes sense. The worksheet strengthens subjects, predicates, nouns, pronouns, subject-verb agreement, complete thoughts, and sentence construction. It is especially useful for students in grades 4-6 who understand that something is missing but need focused practice recognizing that every complete sentence must clearly tell who or what it is about.

Instructional Objectives

• Identify the predicate: Students recognize the part of the sentence that tells what someone or something does.
• Supply a clear subject: Learners add a noun or pronoun that logically performs the stated action.
• Check subject-verb agreement: Students make sure the chosen subject matches the verb in number and form.
• Repair a short passage: Children add missing subjects throughout a paragraph so the ideas become complete and connected.

Learning Benefits

• Focuses on one common fragment type: Students practice only subjectless fragments before moving to more complicated errors.
• Uses helpful context clues: Actions such as running, finishing, barking, playing, and knocking guide students toward sensible subjects.
• Supports parent guidance: Adults can ask, “Who did this?” or “What thing performed the action?”
• Includes paragraph-level revision: The final activity shows how missing subjects can make an entire passage confusing.
• No-prep format: The worksheet is ready for grammar lessons, homework, tutoring, or homeschool use.

A sentence may contain a strong action but still be incomplete when the reader does not know who performed it. For example, “ran across the playground” tells what happened, but it needs a subject such as the child, Marcus, or she. Students also learn that their subject must fit the verb, so a plural verb may require a plural subject. As learners complete the individual sentences and revise the paragraph, they strengthen subject recognition, predicate understanding, sentence meaning, agreement, editing fluency, and confidence. In classroom and homeschool settings, this worksheet reinforces the basic question every writer should ask: “Have I clearly told the reader who or what this sentence is about?”
