Compound Subjects Worksheets - 15 Worksheets Library - Free Printable

Let’s go through each problem step by step.

We are told to rewrite each pair of sentences as one sentence using a compound subject.
A compound subject means two or more subjects joined together (usually with “and”) that share the same verb or action.

Problem 1:
Original:
Lily plays the cello. Aaron plays the cello.

Both Lily and Aaron do the same thing — play the cello.
So we can combine them:
→ Lily and Aaron play the cello.

(Note: We change “plays” to “play” because now there are two people doing it.)

Problem 2:
Original:
Yasmine has a pet. Kyle has a pet.

Same idea — both have a pet.
Combine the subjects: Yasmine and Kyle
→ Yasmine and Kyle have a pet.

(“Has” becomes “have” for plural subject.)

---

Problem 3:
Original:
Mary is a teacher. Joel is a teacher.

Both are teachers.
Combine: Mary and Joel
→ Mary and Joel are teachers.

(“Is” becomes “are”, and “teacher” becomes plural “teachers” since there are two.)

---

Problem 4:
Original:
Ryan is an athlete. Pat is an athlete.

Same pattern.
Combine: Ryan and Pat
→ Ryan and Pat are athletes.

(Again, “is” → “are”, “athlete” → “athletes”)

---

Problem 5:
Original:
Jimmy works hard. Sam works hard.

Both work hard.
Combine: Jimmy and Sam
→ Jimmy and Sam work hard.

(“Works” becomes “work” for plural subject.)

---

Final Answer:
1. Lily and Aaron play the cello.
2. Yasmine and Kyle have a pet.
3. Mary and Joel are teachers.
4. Ryan and Pat are athletes.
5. Jimmy and Sam work hard.
