Grade 4 English worksheet on punctuation: question mark, comma, full stop, and capital letters.

Explanation:
Let’s go through each sentence one by one and figure out which punctuation mark is missing.

1. "Why can’t I go to Jim’s birthday party"
This is a question — it starts with "Why", and the speaker is asking something. Questions end with a question mark (?).
✔ Correct choice: A. question mark (?)

2. “Where are you going? the principal asked.”
The quote ends with a question mark already — but notice: after the closing quotation mark, we have “the principal asked.” That’s not part of the quote. In English, when a quote is followed by a tag like *he said* or *she asked*, the punctuation goes inside the quotes — and the sentence should end with a period (because the whole sentence is a statement). But here, the quote already has a question mark inside, and then there's no punctuation before “the principal asked” — actually, the problem is that the question mark is *already there*, so what’s missing? Wait — look again: the sentence is written as:
*“Where are you going? the principal asked.”*
That’s incorrect — there should be no space after the question mark before the closing quote, and the tag “the principal asked” should come *after* the quote, and the whole sentence ends with a period, because it’s a declarative sentence reporting a question. But the question asks: *which punctuation mark is missing?*
Actually, in standard punctuation, when the quote is a question and is followed by a tag, the question mark stays inside the quotes, and the sentence ends normally — no extra punctuation needed after the quote except maybe a period *if* the tag is a full sentence. But here, the sentence as written is missing the period at the very end — because “the principal asked” is a complete clause, and the whole sentence must end with a period. However, looking at the options:
A. period (.)
B. question mark (?)
C. exclamation point (!)
D. quotation mark (" ")
The sentence currently ends with a period — wait, no! In the worksheet, it says:
“Where are you going? the principal asked.
→ It *does* end with a period. So why would a punctuation be missing? Let’s read carefully: the quote is *“Where are you going?* — then directly *the principal asked.* — but in correct writing, it should be:
“Where are you going?” the principal asked.
So the missing punctuation is the closing quotation mark after the question mark. Because right now it’s written as:
“Where are you going? the principal asked.
→ There’s no closing quote before “the principal”. So the missing mark is a quotation mark (“).
✔ Correct choice: D. quotation mark (" ")

3. "Remember, there will be no game tomorrow, being a Monday"
This sentence is a statement — it’s reminding someone of a fact. It doesn’t ask a question, isn’t excited, and doesn’t need a quote. It should end with a period (.). Right now it ends with *Monday* and nothing — so missing punctuation is a period.
✔ Correct choice: A. period (.)

4. "My mom can bake a cake in 24 minutes"
This is a simple statement — not a question, not an exclamation. It should end with a period (.). Currently no punctuation at the end.
✔ Correct choice: A. period (.)

5. "Aren’t you fed up of watching TV"
This is a question — it’s asking if the person is tired of watching TV. Even though it starts with a contraction (*Aren’t*), it’s still a question. So it needs a question mark (?) at the end.
✔ Correct choice: C. question mark (?)

Now let’s double-check all:

1. Question → ? → A
2. Missing closing quote → D
3. Statement → . → A
4. Statement → . → A
5. Question → ? → C

Yes, that matches standard punctuation rules.

Final Answer:
1. A
2. D
3. A
4. A
5. C
