Who Did What? A Helpful Subject and Predicate Worksheet
Every sentence is like a mini-story. It needs a “who” (the subject) and a “what happened” (the predicate). Once students can identify these two parts, they’ll start writing stronger, clearer sentences.
Grammar doesn’t have to feel overwhelming. That’s why we created the Who Did What? Subject and Predicate Worksheet for students in 1st- 3rd grade. Students are asked to circle the complete subject (who or what the sentence is about) and underline the complete predicate (what the subject did). This format gives learners a visual, hands-on way to understand sentence structure and begin identifying these parts in their reading and writing.
Some teachers use this worksheet as a warm-up before a writing lesson. Others like to keep it handy for grammar centers or reading time. It also pairs nicely with a subject, predicate anchor chart, or sentence-building activity. The goal is to give students repeated exposure in different ways, so they develop fluency and confidence.
Building Strong Sentence Structure: Kindergarten Through Third Grade
From kindergarten through third grade, students develop essential sentence structure skills. This developmental progression builds systematically, with each grade level preparing students for more complex language tasks.
Kindergarten Foundation
- Use simple subject-verb constructions like “The dog runs”
- Practice proper capitalization and end punctuation
- Build vocabulary for oral and written expression
First Grade Expansion
- Identify complete versus incomplete sentences
- Create detailed constructions like “The big, brown dog runs quickly”
- Connect ideas using words like “and”
- Develop consistent capitalization and punctuation habits
Second Grade Analysis
- Identify subjects and predicates in sentences
- Work with various sentence types (statements, questions, exclamations)
- Use prepositional phrases to add detail
Third Grade and Above
- Master compound subjects and predicates
- Revise run-on sentences and fragments
- Use sentence variety strategically in writing
- Identify and correct problematic sentences independently
- Apply skills across all academic subjects
