Subject and Predicate worksheet for students to practice adding compound subjects and predicates to sentences.

The task asks us to take each sentence and add parts so that it has both a compound subject and a compound predicate.

Let’s break down what that means:

- A compound subject means there are two or more subjects (people, things, animals) doing something — joined by “and” or “or”.
- A compound predicate means the subject is doing two or more actions — also usually joined by “and” or “or”.

So we need to rewrite each sentence to include:
→ Two or more subjects (e.g., “The snail and the turtle”)
→ Two or more verbs/actions (e.g., “crawled and rested”)

We’ll go one by one.

---

1. Original: *The snail is slow.*
→ Add another subject: “The snail and the slug”
→ Add another action: “are slow and move carefully”
✔ Revised: *The snail and the slug are slow and move carefully.*

2. Original: *The night was long.*
→ Add subject: “The night and the day”
→ Add action: “were long and seemed endless”

4. Original: *Chris forgot his hat.*
→ Add subject: “Chris and Alex”
→ Add action: “forgot their hats and left without them”
✔ Revised: *Chris and Alex forgot their hats and left without them.*

5. Original: *It is time to get up.*
→ This is tricky — “it” is not really a person. Let’s make it about people.
→ Add subject: “Mom and Dad”
→ Add action: “are calling us and want us to get up”
✔ Revised: *Mom and Dad are calling us and want us to get up.*

6. Original: *The kids are excited.*
