Let's solve this worksheet step by step. The task is to add appropriate conjunctions to each sentence to make it grammatically correct and meaningful.

🔹 What are Conjunctions?

Conjunctions are words that connect words, phrases, or clauses. Common ones include:
- Coordinating conjunctions: *and, but, or, nor, for, so, yet*
- Subordinating conjunctions: *because, although, since, when, while, so that, after, before, until, etc.*

We'll use these to complete the sentences.

✔ Now, let’s go through each sentence:

---

1. The teacher read the book slowly ___ they could understand.

- We need a conjunction that shows purpose or reason.
- "So that" fits perfectly: *"so that they could understand."*
- ✔ Answer: so that

> ✔️ Final sentence: *The teacher read the book slowly so that they could understand.*

2. The computer was used ___ research projects.

- This needs a preposition or conjunction showing purpose.
- But we're adding a conjunction, not a preposition.
- However, “for” is a preposition, not a conjunction.
- Let's reconsider: perhaps it's missing a coordinating conjunction? But this sentence has only one clause.
- Wait — maybe it's incomplete. Actually, this might be a typo or misphrasing. But if we assume it should be something like:
> "The computer was used ___ research projects were completed."
- But as written, it's likely meant to be:
> "The computer was used for research projects." → But "for" is not a conjunction.
- Alternatively, maybe it's supposed to be:
> "The computer was used in order that research projects..." → But again, "in order that" is a subordinating conjunction phrase.

Wait — perhaps the intended answer is "to", but that's not a conjunction either.

Actually, looking at the pattern of the other sentences, this seems like it might be missing a subordinating conjunction such as "so that".

But here’s the issue: the sentence is currently:
> "The computer was used ___ research projects."

This is not a complete thought unless there's more context.

However, if we interpret it as:
> "The computer was used ___ research projects could be done."

Then "so that" would work.

✔ So likely, the intended answer is: so that

> ✔️ Final sentence: *The computer was used so that research projects could be done.* (Assuming implied continuation)

But since the original says just "research projects", maybe it's a typo.

Alternatively, if we consider "for" as a possible choice, but it's not a conjunction.

Wait — "and" doesn't make sense here.

Best fit: "so that" (even though it's not listed in the original, it's commonly taught).

✔ Answer: so that

3. After they painted the hung up their artwork ___ that it could dry.

- There's a typo: "the hung up" → should be "they hung up"
- So corrected: "After they painted, they hung up their artwork ___ that it could dry."
- We need a conjunction to show purpose.
- "So that" makes sense: *"so that it could dry."*

✔ Answer: so that

> ✔️ Final sentence: *After they painted, they hung up their artwork so that it could dry.*

4. Pip trained ___ the Cross Country running race.

- This is about preparation for an event.
- "For" is a preposition, but again, not a conjunction.
- But if we think of the full idea: "Pip trained in order to win the race" — but "in order to" isn't a conjunction.
- Or: "Pip trained so that he could win the race."

But the sentence ends with "race" — so likely missing a clause.

Possibility: "Pip trained ___ the Cross Country running race would be successful."

Then "so that" fits.

✔ Answer: so that

> ✔️ Final sentence: *Pip trained so that the Cross Country running race would be successful.* (or better: *Pip trained so that he could succeed in the race.*)

But given the wording, "so that" is the best conjunction.

5. Her parents ____ swim coach were proud of her.

- Two people: her parents and the swim coach.
- So we need a conjunction connecting them.
- "And" connects two subjects.

✔ Answer: and

> ✔️ Final sentence: *Her parents and swim coach were proud of her.*

Note: It's a bit awkward; probably meant to be "*her parents and the swim coach*" — but assuming "swim coach" is meant as a noun phrase.

---

6. They tried their best ____ didn't win the game.

- Two independent clauses: "They tried their best" and "didn't win the game."
- We need a conjunction showing contrast.
- Best choice: but

✔ Answer: but

> ✔️ Final sentence: *They tried their best but didn't win the game.*

---

7. The baker put the bread in the oven ____ waited until it was ready.

- Two actions: putting bread in oven, then waiting.
- Sequential events — use and

✔ Answer: and

> ✔️ Final sentence: *The baker put the bread in the oven and waited until it was ready.*

---

8. Sam baked a cake ____ the school fundraiser.

- Likely meaning: Sam baked a cake for the school fundraiser.
- But "for" is a preposition.
- However, if we say: "Sam baked a cake so that the school fundraiser would have a treat..."
- Then "so that" works.

But again, the sentence is incomplete.

Alternatively, maybe it's: "Sam baked a cake and donated it to the school fundraiser."

But that changes the sentence.

Given the structure, most likely intended: "for" — but again, not a conjunction.

Wait — perhaps the intended conjunction is "to" — but that's not a conjunction.

Hmm.

But in some contexts, "to" can be used as part of an infinitive, but still not a conjunction.

Alternatively, if the sentence is: "Sam baked a cake for the school fundraiser" — no conjunction needed.

But the task says add a conjunction.

So likely, the intended sentence is:
> "Sam baked a cake so that the school fundraiser would succeed."

But as written, it's unclear.

Another possibility: "Sam baked a cake and brought it to the school fundraiser."

But again, not what's written.

Best guess: "for" is not a conjunction.

Wait — perhaps it's "to"?

No — not a conjunction.

Maybe the blank is meant to be "for" even though it's not a conjunction? But the title says "conjunctions".

Alternatively, perhaps the sentence is:
> "Sam baked a cake to help the school fundraiser."

Then "to" is an infinitive marker — not a conjunction.

But maybe the intended answer is "so that" again.

Let’s suppose:
> "Sam baked a cake so that the school fundraiser could have dessert."

Then "so that" is the correct conjunction.

✔ Answer: so that

> ✔️ Final sentence: *Sam baked a cake so that the school fundraiser could succeed.*

9. The car stopped ___ that the ducks could safely cross the road.

- Clearly, this is asking for a purpose.
- "So that" fits perfectly.

✔ Answer: so that

> ✔️ Final sentence: *The car stopped so that the ducks could safely cross the road.*

---

10. The tiger ____ her cubs lay in the sun.

- Two subjects: "the tiger" and "her cubs"
- Both lying in the sun.
- Need a conjunction to join them.
- Use and

✔ Answer: and

> ✔️ Final sentence: *The tiger and her cubs lay in the sun.*

---

📝 Summary of Conjunctions Used:

- so that – for purpose
- and – to join similar ideas
- but – for contrast

These are all common subordinating or coordinating conjunctions.

💡 Tip:

Always look at the relationship between the parts of the sentence:
- Purpose? → so that
- Contrast? → but
- Addition? → and

This helps choose the right conjunction.
