In this unit
You will practise in, on and at for place and time. You will also learn three more past forms: see → saw, come → came, eat → ate.
in the room · on the table · at school · in the morning · on Monday · at seven o'clock
Remember: use for and since later, when you study the present perfect.
Step 1. Where is it? In, on or at
Look at the objects. Your teacher can use real objects in the classroom to show the meaning.
Exercise 1. Choose in, on or at
These are common patterns, not a complete list of every use of each preposition.
Step 2. When? In, on or at
We also use these prepositions with time expressions.
| Use | Examples |
|---|---|
| in | in the morning, in the afternoon, in July |
| on | on Monday, on Friday morning, on 12 May |
| at | at seven o'clock, at noon, at night |
Exercise 2. Complete with in, on or at
Step 3. More past verbs
These verbs do not add -ed. Learn the past forms in sentences.
| Present | Past | Example |
|---|---|---|
| see | saw | I see my friend every day. I saw her yesterday. |
| come | came | He comes here on Monday. He came here yesterday. |
| eat | ate | We eat lunch at one. We ate lunch at one yesterday. |
Exercise 3. Choose the past form
Step 4. Questions about the past
Use Did + person + basic verb? After did, say see, not saw.
Did he come on Monday? — No, he didn't.
Did they eat at home? — Yes, they did.
Exercise 4. Complete the question
Step 5. Choose the tense
Look at the time expression. Is the sentence about a routine, something happening now, an arrangement, or the past?
Exercise 5. Choose the correct verb form
Step 6. Read and practise
The text includes a few past forms that will be studied more fully later. For now, use the context to understand the story and notice the target prepositions and familiar tenses.
Exercise 6. Answer the questions
Step 7. Your English
Write or say four sentences about your life. Use the examples to help you.
I work / study in the …
On …, I usually …
Yesterday, I …
Tomorrow evening, I'm …
These are personal answers. Read them aloud and check that your time expressions and verb forms agree.
Teacher's note
Use real classroom objects to show in and on, and familiar locations to establish at. For time, use a clock, a weekly calendar and examples from learners' routines. Explain only the patterns needed for this lesson; these prepositions have other uses that can be introduced gradually.
Recycle present simple, present continuous and past simple. The new irregular verbs are saw, came and ate. Do not introduce past participles here: see / saw / seen can wait until the present perfect.
The pace can be adjusted. Learners who already know some English can move through the controlled work quickly; learners who need more support can repeat the oral models, use mime, and practise fewer examples at a time.
