Grade 5 worksheet on coordinating conjunctions with sentence combining exercises.

Let's solve the worksheet step by step. The task is to combine two independent sentences into one sentence using a coordinating conjunction (for, and, nor, but, or, yet, so) and a comma.

---

🔹 Coordinating Conjunctions:

for, and, nor, but, or, yet, so

We’ll use these to join two related ideas logically.

---

Now let’s go through each pair:

---

1. We are going to the store now. You won’t have to go later.

→ These are connected by a cause-effect relationship.
"So" fits best here.

✔ We are going to the store now, so you won’t have to go later.

---

2. I thought I had won the race. I really came in second place.

→ This shows a contrast between expectation and reality.
"But" is appropriate.

✔ I thought I had won the race, but I really came in second place.

---

3. My family is going on vacation. We are going to visit my grandma.

→ These are two related facts. Use "and" for simple addition.

✔ My family is going on vacation, and we are going to visit my grandma.

---

4. We can either eat spaghetti for dinner. We can eat at the local pizza place.

→ This presents two choices. Use "or".

✔ We can either eat spaghetti for dinner, or we can eat at the local pizza place.
*(Note: "either...or" is a correlative conjunction, but since the instruction says to use a coordinating conjunction, we can simplify it as:)*
Alternatively: We can eat spaghetti for dinner, or we can eat at the local pizza place.

✔ We can eat spaghetti for dinner, or we can eat at the local pizza place.

5. He didn’t go to the wedding. He still sent the bride and groom a present.

→ This shows contrast — he didn't attend but did something kind.
Use "but".

✔ He didn’t go to the wedding, but he still sent the bride and groom a present.

---

6. They had a lot of money. They had inherited millions from their grandparents.

→ This explains the reason why they had money.
Use "because"? But “because” is not a coordinating conjunction.
We need one of: for, and, nor, but, or, yet, so.

"For" means "because" and is a coordinating conjunction.

✔ They had a lot of money, for they had inherited millions from their grandparents.

---

7. I tried the new dessert. I really didn’t like the way it tasted.

→ Contrast: tried it, but disliked it.
Use "but".

✔ I tried the new dessert, but I really didn’t like the way it tasted.

---

8. The computer is either broken. The computer needs to be turned on.

→ This seems to suggest a choice or possibility.
But the structure is awkward. Let's rephrase:
Possibility: maybe it's broken, or maybe it just needs to be turned on.

Use "or".

✔ The computer is either broken, or it needs to be turned on.

✔ Final Answers:

1. We are going to the store now, so you won’t have to go later.
2. I thought I had won the race, but I really came in second place.
3. My family is going on vacation, and we are going to visit my grandma.
4. We can eat spaghetti for dinner, or we can eat at the local pizza place.
5. He didn’t go to the wedding, but he still sent the bride and groom a present.
6. They had a lot of money, for they had inherited millions from their grandparents.
7. I tried the new dessert, but I really didn’t like the way it tasted.
8. The computer is either broken, or it needs to be turned on.

💡 Tips:

- Always check if the two sentences are independent clauses (can stand alone).
- Choose the conjunction that makes the most sense:
- and = addition
- but = contrast
- or = choice
- so = result
- for = reason (like "because")
- yet = contrast (similar to but, more formal)
- nor = negative addition
