Worksheet on identifying compound subjects in sentences.

Let’s go through each sentence one by one to find the compound subject — that means, two or more subjects joined by “and” (or sometimes “or”) in the same sentence.

---

1. Helen and her little sister are playing with their pet cat.
→ Subjects: *Helen* and *her little sister* → joined by “and” → ✔ Compound subject

2. Either Megan or Maria built the shoe house.
→ This uses “either...or” — not “and”. So it’s NOT a compound subject. ✘

3. Neither Dad nor Mom is at home.
→ Uses “neither...nor” — again, not “and”. Not a compound subject. ✘

4. Sunlight and moonlight are both essential for life.
→ Subjects: *Sunlight* and *moonlight* → joined by “and” → ✔ Compound subject

5. Mimi, Charlie, and Ava are sleeping.
→ Three subjects: *Mimi*, *Charlie*, and *Ava* → all joined by commas and “and” → ✔ Compound subject

6. The ducks and frogs are swimming in the pond.
→ Subjects: *The ducks* and *frogs* → joined by “and” → ✔ Compound subject

7. Martha or Kevin is going to do the dishes today.
→ Uses “or” — not “and”. Not a compound subject. ✘

8. Grandpa and I made this cake together.
→ Subjects: *Grandpa* and *I* → joined by “and” → ✔ Compound subject

9. Neither the rabbits nor the chairs have been cleaned.
→ Again, “neither...nor” — not “and”. Not a compound subject. ✘

10. Either Tomas or Maribel has broken the window.
→ “Either...or” — not “and”. Not a compound subject. ✘

Now let’s list only the sentences that have compound subjects:

✔ Sentence 1
✔ Sentence 4
✔ Sentence 5
✔ Sentence 6
✔ Sentence 8

That’s 5 sentences total.
