Show Answer Key & Explanations Step-by-step solution for: Simple Subject and Simple Predicate | 3rd Grade Worksheets
Let’s go through each sentence one by one.

We are looking for:
- Simple Subject: The main noun or pronoun that the sentence is about — no extra words like “the”, “a”, or adjectives.
- Simple Predicate: The main verb (action or state of being) — again, just the verb itself, not helping verbs or modifiers.

Remember:
Example given:
“My mother reads a book.” → Simple subject = “mother”, Simple predicate = “reads”

Now let’s do each sentence:

---

1. The teacher graded the homework papers.
→ Who did the action? “teacher” (ignore “the”)
→ What did they do? “graded”
Simple Subject: teacher
Simple Predicate: graded

---

2. John drove the car to the store.
→ Who? “John”
→ Did what? “drove”
Simple Subject: John
Simple Predicate: drove

---

3. We liked the last play of the game.
→ Who? “We”
→ Did what? “liked”
Simple Subject: We
Simple Predicate: liked

---

4. They were singing in the park.
→ Who? “They”
→ Action? “were singing” — but we want ONLY the main verb. “Singing” is the main verb; “were” is a helping verb. So simple predicate = “singing”
Simple Subject: They
Simple Predicate: singing

*(Note: Some teachers might accept “were singing” as the full predicate, but since it says “simple predicate”, we take only the main verb.)*

---

5. On Tuesday the happy children watched a movie.
→ Who? “children” (ignore “the happy”)
→ Did what? “watched”
Simple Subject: children
Simple Predicate: watched

---

6. The scout troop met in the morning.
→ Who? “troop” (ignore “The scout”)
→ Did what? “met”
Simple Subject: troop
Simple Predicate: met

---

7. The pack of dogs ran freely in the street.
→ Who/what? “pack” (this is the main noun — “of dogs” describes it, so ignore)
→ Did what? “ran”
Simple Subject: pack
Simple Predicate: ran

---

8. The sound of the bell is ringing in my ears.
→ What’s the subject? “sound” (“of the bell” describes it)
→ Verb? “is ringing” → main verb is “ringing” (“is” is helping)
Simple Subject: sound
Simple Predicate: ringing

---

9. Swimming is my favorite sport.
→ What is this sentence about? “Swimming” (it’s a gerund acting as a noun)
→ Verb? “is”
Simple Subject: Swimming
Simple Predicate: is

---

10. Lance and Phyllis quickly walked across the street.
→ Who? “Lance and Phyllis” — compound subject, both are simple subjects together
→ Did what? “walked” (“quickly” is an adverb, ignore)
Simple Subject: Lance and Phyllis
Simple Predicate: walked

---

Final Answer:
1. Subject: teacher, Predicate: graded
2. Subject: John, Predicate: drove
3. Subject: We, Predicate: liked
4. Subject: They, Predicate: singing
5. Subject: children, Predicate: watched
6. Subject: troop, Predicate: met
7. Subject: pack, Predicate: ran
