"Comma Usage Practice Worksheet for students to learn correct comma placement in sentences."

Let’s go step by step to fix each sentence by adding commas where needed, based on the rules given:

Rule 1: Use a comma between city and state → “Albany, New York”
Rule 2: Use a comma between day and year in a date → “December 1, 1976”
Rule 3: Use commas when listing 3 or more things → “lettuce, chicken, and yogurt”

Now let’s apply these to each sentence:

1) My father was born on December 1 1976.
→ Add comma after “1” (day and year rule)
✔ Corrected: My father was born on December 1, 1976.

2) Caroline lives in Albany New York.
→ Add comma between city and state
✔ Corrected: Caroline lives in Albany, New York.

3) My dad needs to buy lettuce chicken and yogurt at the grocery store.
→ List of 3 items: add commas after “lettuce” and before “and”
✔ Corrected: My dad needs to buy lettuce, chicken, and yogurt at the grocery store.

4) I saw two rabbits a deer and five squirrels on my hike this morning.
→ List of 3 things: rabbits, deer, squirrels → add commas
✔ Corrected: I saw two rabbits, a deer, and five squirrels on my hike this morning.

5) Barack Obama was first inaugurated on January 20 2009.
→ Date: add comma after “20”
✔ Corrected: Barack Obama was first inaugurated on January 20, 2009.

6) Rockets take off from Cape Canaveral Florida.
→ City and state: add comma
✔ Corrected: Rockets take off from Cape Canaveral, Florida.

7) She would like to go on a vacation to Rome Italy.
→ City and country? Wait — the rule says “city and state”, but here it’s “Rome, Italy”. Even though Italy is a country, we still use a comma between city and country in standard English. The worksheet example uses “Los Angeles, California” (state), but same logic applies for countries too. So yes — add comma.
✔ Corrected: She would like to go on a vacation to Rome, Italy.

8) Sherry enjoys reading dancing and acting.
→ List of 3 activities → add commas
✔ Corrected: Sherry enjoys reading, dancing, and acting.

9) He needs to wash the car do the laundry and make dinner.
→ List of 3 chores → add commas
✔ Corrected: He needs to wash the car, do the laundry, and make dinner.

10) My baby sister was born on April 20 2009.
→ Date: add comma after “20”
✔ Corrected: My baby sister was born on April 20, 2009.

11) Her best friend lives in Laguna Beach California.
→ City and state → add comma
✔ Corrected: Her best friend lives in Laguna Beach, California.

All done! Let me double-check each one against the rules — looks good.

1) My father was born on December 1, 1976.
