Prepositions of time worksheet for grammar practice.

Let's solve this grammar worksheet step by step.

---

Task:

Complete the chart below by placing each time expression under the correct preposition: at, in, or on.

We are given a list of time expressions:

- the morning
- Sunday
- Tuesday afternoon
- spring
- noon / midday
- February
- winter
- 2013
- my birthday
- a weekday
- the evening
- a holiday
- 10:30
- May 5
- the afternoon
- the weekend
- Monday morning
- summer
- Wednesday evening
- night
- fall / autumn
- the 1990s
- bedtime

And we need to sort them into three columns based on the correct preposition used with each time expression.

Rules for Prepositions of Time:

1. At – used for specific times (hours, minutes, meals, events).
- e.g., at 10:30, at noon, at midnight, at bedtime

2. On – used for days, dates, specific parts of days, holidays.
- e.g., on Sunday, on May 5, on Tuesday afternoon, on my birthday, on a weekday, on the weekend, on Monday morning, on Wednesday evening

3. In – used for months, years, seasons, parts of the day (morning, afternoon, evening), long periods.
- e.g., in February, in 2013, in winter, in the morning, in the afternoon, in the evening, in spring, in the 1990s, in summer, in the weekend (note: "the weekend" is often used with "on", but "in the weekend" can be acceptable in some contexts — however, standard usage is on)

> Note: “The weekend” is typically used with on (e.g., on the weekend). However, “in the weekend” is sometimes used in British English, but it's less common. For standard American English, use on.

Now, let’s sort the expressions:

#### ✔ AT
Used for:
- Specific times
- Meals or fixed events
- Short, precise moments

Expressions:
- 10:30 → at 10:30
- noon / midday → at noon
- midnight → at midnight
- bedtime → at bedtime

✔ So, at:
- 10:30
- noon / midday
- midnight
- bedtime

---

#### ✔ ON
Used for:
- Days of the week
- Dates (specific days)
- Parts of days with a specific day
- Holidays
- Specific mornings/afternoons/evenings

Expressions:
- Sunday → on Sunday
- Tuesday afternoon → on Tuesday afternoon
- my birthday → on my birthday
- a weekday → on a weekday
- May 5 → on May 5
- Monday morning → on Monday morning
- Wednesday evening → on Wednesday evening
- the weekend → on the weekend
- a holiday → on a holiday

✔ So, on:
- Sunday
- Tuesday afternoon
- my birthday
- a weekday
- May 5
- Monday morning
- Wednesday evening
- the weekend
- a holiday

---

#### ✔ IN
Used for:
- Months
- Years
- Seasons
- Parts of the day (general)
- Decades

Expressions:
- the morning → in the morning
- February → in February
- winter → in winter
- 2013 → in 2013
- spring → in spring
- the evening → in the evening
- the afternoon → in the afternoon
- night → in the night (or at night — both possible, but in the night is more formal; at night is more common)
- fall / autumn → in fall / in autumn
- summer → in summer
- the 1990s → in the 1990s

> Note: “At night” is more common than “in the night” in everyday speech. But “in the night” is acceptable in formal writing. Since the worksheet likely expects standard usage, at night would go under at, but here “night” appears without “the” — so we must consider context.

Wait: The list has just night, not “at night” or “in the night”.

But in grammar, we say:
- at night (common)
- in the night (less common, poetic/formal)

So night alone should go under at? But the word is listed as “night”, not “at night”.

Actually, the phrase is just “night” — so it's ambiguous. But in most grammar rules, night is used with at when referring to general time: at night.

Similarly, bedtime is at bedtime.

So:
- night → at night → at

But the list says just “night” — so we treat it like a noun that requires “at”.

However, if it were “in the night”, it would be in.

But since it's just “night”, and no article, we assume at night.

So:
- night → at

But wait — look again: the list includes “night” and also “the evening”, “the afternoon”, etc.

So:
- the evening → in the evening (so in)
- the afternoon → in the afternoon (so in)
- the morning → in the morning (so in)
- night → at night (so at)

Yes.

So correction:
- night → at

But earlier I put it under in — that was wrong.

So final decision:
- night → at

Also, “the weekend” — is it on or in?

Standard rule: on the weekend (American English) or at the weekend (British English). But in the weekend is incorrect.

So on the weekend → on

Therefore, the weekend → on

Final Sorting:

#### AT
- 10:30
- noon / midday
- midnight
- bedtime
- night

> Note: “night” is usually used with “at” — at night

#### ON
- Sunday
- Tuesday afternoon
- my birthday
- a weekday
- May 5
- Monday morning
- Wednesday evening
- the weekend
- a holiday

#### IN
- the morning
- February
- winter
- 2013
- spring
- the evening
- the afternoon
- fall / autumn
- summer
- the 1990s

> Note: “the evening” → in the evening
> “the afternoon” → in the afternoon
> “the morning” → in the morning
> “the 1990s” → in the 1990s
> “2013” → in 2013
> “February” → in February
> “spring” → in spring
> “winter” → in winter
> “fall / autumn” → in fall / in autumn
> “summer” → in summer

✔ Final Answer:

| at | in | on |
|--------|--------|--------|
| 10:30 | the morning | Sunday |
| noon / midday | February | Tuesday afternoon |
| midnight | winter | my birthday |
| bedtime | 2013 | a weekday |
| night | spring | May 5 |
| | the evening | Monday morning |
| | the afternoon | Wednesday evening |
| | fall / autumn | the weekend |
| | summer | a holiday |
| | the 1990s | |

> Note: "night" goes under at, even though it's listed without "at". In grammar, we pair it with "at".

✔ Explanation Summary:

- Use at for specific times: 10:30, noon, midnight, bedtime, night.
- Use on for days, dates, and specific parts of days: Sunday, May 5, Tuesday afternoon, my birthday, the weekend.
- Use in for longer periods: months, years, seasons, parts of the day (morning, afternoon, evening): February, 2013, spring, the morning, the evening, etc.

This completes the worksheet correctly.
