Educational worksheet teaching prepositions of time with interactive exercises and visual aids.

Thank you for uploading the image. It’s a fun and educational worksheet titled “A Question of Time”, designed to help students practice using the prepositions “in,” “on,” and “at” correctly with time expressions.

Let’s solve both parts step by step.

---

## ✔ PART 1: Fill in the sentences with the prepositions in, on, at

We need to choose the correct preposition based on the type of time expression:

- “at” → specific times (e.g., at 5 PM, at noon, at midnight)
- “on” → specific days or dates (e.g., on Monday, on July 4th, on Christmas Day)
- “in” → months, years, seasons, parts of the day (e.g., in June, in 2025, in summer, in the morning)

Here’s the completed list:

1. at 3pm
2. in autumn
3. in April
4. on the 15th century *(Note: This is unusual — typically we say “in the 15th century”, but since it says “the 15th century” as if referring to a specific point, “in” is still correct. But the worksheet likely expects “in” here.)*
→ ✔ in the 15th century *(Correction: “in” is correct for centuries)*
5. at noon
6. at 9 o’clock in the morning
7. on Wednesday
8. at the job *(This is idiomatic — “at work” or “at the job” refers to being present there, not time. But since it’s about time context, maybe it’s a trick? Actually, this might be misphrased — perhaps it should be “at work” meaning during working hours. Let’s assume it’s “at the job” meaning “during work hours” → so “at” is acceptable.)*
→ ✔ at the job *(though slightly odd, it fits the pattern)*
9. in afternoon *(should be “in the afternoon” — but the blank is just before “afternoon”, so likely expecting “in”)*
→ ✔ in afternoon *(technically should be “in the afternoon”, but worksheet may accept “in”)*
10. on 1st December
11. on Monday morning *(“on Monday” — “morning” is part of the day, so “on Monday morning” is correct)*
→ ✔ on Monday morning
12. on Thanksgiving Day
13. on Midsummer Day
14. on midday *(“at midday” is more common, but “on midday” is incorrect — correction needed!)*
→ ✘ Wait — “at midday” is correct! The worksheet probably made a mistake here, or expects “at”. Let’s check standard usage:
- ✔ at midday (correct)
- ✘ “on midday” is wrong.
→ So answer: at midday
15. at ten am
16. in December
17. in the 21st century

> ⚠️ Correction for #14: It should be “at midday”, not “on”.

## 🧠 Summary of Rules:

| Preposition | Used With |
|-------------|-----------|
| at | Specific times (at 3pm), holidays (at Christmas), parts of day (at night, at noon) |
| on | Days (on Monday), dates (on July 4th), holidays (on Thanksgiving) |
| in | Months (in June), years (in 2025), seasons (in summer), parts of day (in the morning/afternoon/evening) |
