Simple sentence expansion worksheet for students to practice grammar and sentence structure.

Let’s break this down step by step.

The worksheet is teaching how to expand a simple sentence by adding more details — like what kind, who or what, did what, and where/when.

The original simple sentence is:
“A puppy played.”

We’re going to fill in the table to make it more detailed.

---

Step 1: Look at the first column — “A, An, The”
It already has “A” filled in. That’s fine. We can keep it as “A” unless we want to change it later for variety.

Step 2: Adjective (What kind?)
We need to add a word that describes the puppy. For example:
→ “fluffy”, “cute”, “small”, “brown”, “happy”
Let’s pick “cute” — it’s simple and common for kids.

Step 3: Noun (Who or What?)
Already filled: “puppy” — good.

Step 4: Verb (Did What?)
Already filled: “played” — good.

Step 5: Where? When? (Circle the one you want)
We can choose either “where” or “when”. Let’s pick “where” because it’s easy to imagine.
Examples: “in the yard”, “at the park”, “on the rug”
Let’s go with “in the yard”

Now let’s put it all together:

Original: A puppy played.
Expanded: A cute puppy played in the yard.

That’s a complete expanded sentence with all parts added.

Final Answer:
A cute puppy played in the yard.
