Past Continuous: Actions in Progress

What this session covers

The past continuous tense describes an action that was happening — in progress — at a particular moment in the past. It is the tense we use when we want to paint a picture of what was going on at a certain time, rather than simply saying what happened. Many learners find the past continuous difficult because their own language may not have a separate form for 'an action in progress'. Understanding this tense well will help you explain it clearly and help your learners use it with confidence.

Personal Reflection

Before you start — think honestly about your own teaching and experience.

Q1
Think about a time you described a scene to someone — for example, when you arrived somewhere and something was already happening. How did you describe what was going on when you arrived?
Q2
Which of these have you seen your learners do when trying to use this tense: use 'was' without the -ing verb, forget 'was/were' entirely, or use the past continuous when the simple past would be more natural?

Discover the Pattern

Look at the examples. Answer each question before reading the explanation — this is how your students will learn too.

1
At 7 o'clock this morning, the teacher wrote on the board.
At 7 o'clock this morning, the teacher was writing on the board.

Both sentences are about 7 o'clock this morning. But do they give us the same picture? What is different about what we understand from each sentence?

The first sentence — 'the teacher wrote on the board' — tells us this happened and was completed at that time. The second — 'was writing' — tells us the action was already in progress at 7 o'clock. It started before 7 and may have continued after. The past continuous gives us a feeling of being inside the moment, like a camera that is running. The simple past is more like a photograph — it shows a finished event. This distinction is subtle but important.

2
The students were singing when the head teacher walked in.
The teacher was explaining the lesson when the bell rang.

There are two actions in each sentence. Which action was already in progress? Which action happened suddenly?

In both sentences, the past continuous verb (were singing, was explaining) shows the background action — the one already in progress. The simple past verb (walked in, rang) shows the new, sudden event that happened during the background action. This is one of the most common uses of the past continuous: to set the scene for another action. The word 'when' is often a signal that the two tenses will appear together in this way.

3
She was working. → Was she working? → She wasn't working.
They were listening. → Were they listening? → They weren't listening.

Look at how the sentences change for questions and negatives. What moves? What stays the same?

In the past continuous, 'was/were' is the auxiliary — it does the grammatical work. To make a question, we move 'was/were' to the front of the sentence (before the subject). To make a negative, we add 'not' after 'was/were' — giving 'was not/wasn't' or 'were not/weren't'. The -ing form of the main verb never changes. This is similar to how present continuous questions work, which may help learners who already know that tense.

The Pattern — What You Just Discovered

The past continuous is formed with was/were + the -ing form of the verb. It describes an action that was in progress at a specific moment in the past. It is often used to describe a background action that was happening when another (shorter) action occurred.
FormUse / MeaningExample
Form Example Notes
Positive (I/he/she/it) She was marking the books. Use 'was' with singular subjects.
Positive (we/you/they) The students were working quietly. Use 'were' with plural subjects.
Negative (I/he/she/it) He wasn't listening. was + not + -ing form
Negative (we/you/they) They weren't paying attention. were + not + -ing form
Question (I/he/she/it) Was she writing on the board? Move 'was' before the subject.
Question (we/you/they) Were the children singing? Move 'were' before the subject.
Special Rule / Notes

VERBS THAT DON'T NORMALLY USE CONTINUOUS FORMS
Some verbs in English describe states rather than actions — they are about how things are, not what is happening. Common examples include: know, understand, believe, want, need, like, love, hate, see, hear, seem, belong. These verbs are not normally used in the continuous form. We do not usually say 'She was knowing the answer' — we say 'She knew the answer.' This rule applies to all continuous tenses, not just the past continuous. At this level, it is enough to point out that these verbs prefer the simple form. If a learner asks 'Was she understanding the lesson?', gently redirect them to 'Did she understand the lesson?' — which uses the simple past.

THE DIFFERENCE BETWEEN 'WHEN' AND 'WHILE'
Both words can introduce a past continuous clause, but there is a small difference. 'When' is more often used with the simple past (the shorter, completed action): 'When the bell rang...'. 'While' is more naturally used with the past continuous (the background, ongoing action): 'While the students were working...'. Both are correct in many contexts, but this tendency is useful for learners to notice.

WHICH TENSE DO I NEED? — A QUICK GUIDE • Was the action in progress at a specific moment in the past? → Past continuous (was/were + -ing). • Did the action start and finish quickly? → Simple past. • Is one action the background and another is a sudden event? → Background = past continuous / Sudden event = simple past. • Is the verb a state verb (know, want, believe, need)? → Do not use continuous — use simple past. • Is the subject singular (I/he/she/it)? → Use 'was'. Is it plural (we/they) or 'you'? → Use 'were'.

Common Student Errors

I was go to the market.
I was going to the market.
WhyThe past continuous needs the -ing form of the main verb, not the base form. 'Was go' is not a correct form in English.
The children was playing outside.
The children were playing outside.
Why'The children' is a plural subject, so we use 'were', not 'was'.
When I arrived, she cooked.
When I arrived, she was cooking.
Why'She cooked' suggests she started and finished cooking after you arrived. If the cooking was already in progress when you arrived, we need the past continuous: 'she was cooking'.
She was knowing the answer.
She knew the answer.
Why'Know' is a state verb. State verbs are not normally used in continuous forms. Use the simple past instead.
Were you work late yesterday?
Were you working late yesterday?
WhyThe past continuous question needs the -ing form after 'were'. 'Work' should be 'working'.

Check Your Understanding — Part 1

Choose the correct form to complete each sentence.

The students ______ (work) quietly when the inspector walked in.___________
______ the teacher ______ (explain) the rule when the bell rang?___________
At this time yesterday, I ______ (mark) my students' books.___________
The children weren't ______ (listen) when the teacher gave the instructions.___________
While some students ______ (read), others were drawing pictures.___________

Check Your Understanding — Part 2: Why Is It Wrong?

Each sentence contains one error. Write the correct sentence and explain the mistake.

The teacher was write the date when I arrived.
Write the correct sentence:
Explain why it is wrong:
The teacher was writing the date when I arrived.
The past continuous needs the -ing form of the main verb. 'Write' should be 'writing'.
All the students was sitting down quietly.
Write the correct sentence:
Explain why it is wrong:
All the students were sitting down quietly.
'All the students' is a plural subject, so we need 'were', not 'was'.
She was wanting to ask a question but she felt shy.
Write the correct sentence:
Explain why it is wrong:
She wanted to ask a question but she felt shy.
'Want' is a state verb and is not normally used in the continuous form. Use the simple past 'wanted' instead.
Were the teacher explaining the exercise when you came in?
Write the correct sentence:
Explain why it is wrong:
Was the teacher explaining the exercise when you came in?
'The teacher' is a singular subject, so we need 'was', not 'were'.

Classroom Teaching Sequence

Use this sequence directly in class — guided discovery, no textbook needed. Tap each step to mark it done.

0 / 5 done
1

STEP 1 — SET THE SCENE (5 minutes): Ask learners to close their eyes and think about this morning — what were they doing at exactly 6 a.m.? Give them 30 seconds to think. Then ask a few learners to share. Write their sentences on the board and underline the past continuous verbs. If a learner gives a simple past answer, gently reshape it: 'So at 6 a.m., you were cooking — the cooking was already in progress, right?'

2

STEP 2 — NOTICE THE FORM (5 minutes): Point to the sentences on the board. Ask: 'What two things do you see in every verb phrase?' Guide learners to notice was/were and the -ing ending. Write the pattern on the board clearly: WAS / WERE + verb-ing. Ask: 'When do we use was? When do we use were?' Elicit or explain the singular/plural rule.

3

STEP 3 — SENTENCE PAIRS (8 minutes): Say two sentences aloud and ask learners which gives a 'fuller picture' of the scene. For example: 'The children played outside' versus 'The children were playing outside.' Then add a second action: 'When it started to rain.' Ask: 'Which version works better with this?' Repeat with one or two more pairs. Help learners feel the difference rather than just memorise a rule.

4

STEP 4 — BUILD A STORY (7 minutes): Ask learners to think about something that was happening in the classroom or school yesterday. Guide them to produce two sentences: one past continuous (background) and one simple past (new event). For example: 'The students were answering questions when the power went off.' Ask pairs to share and give feedback on the form.

5

STEP 5 — QUESTIONS AND NEGATIVES (5 minutes): Write one positive past continuous sentence on the board. Ask learners to make it a question, then a negative. Repeat two or three times with different subjects. Focus especially on the movement of 'was/were' to the front for questions, and 'wasn't/weren't' for negatives. End with two or three learner-generated examples.

Ready-to-Use Classroom Materials

Use directly in class — copy, adapt, or read aloud. No printing needed.

1 What Were You Doing? (Spoken activity)
Ask learners to work in pairs. One learner says a time (e.g. 'last Sunday at 10 a.m.'). The other must say what they were doing at that time using the past continuous. Then swap. Encourage learners to ask a follow-up question: 'Were you alone?' 'Was anyone else there?' This gives natural practice with questions and negatives.
Example sentences
A: Last Sunday at 10 a.m.?
B: I was washing clothes. My sister was helping me.
A: Were you using a machine or washing by hand?
B: We were washing by hand. We weren't using a machine — we don't have one.
2 When the Bell Rang... (Sentence completion)
Say the beginning of a sentence and ask learners to complete it using the past continuous. Go around the class and give each learner a turn. Encourage variety — different subjects, different activities.
Example sentences
Teacher: 'When the head teacher walked in, the students were...'
Learner: '...were writing in their notebooks.'
Teacher: 'When the rain started, I was...'
Learner: '...was walking home from school.'
Teacher: 'At 8 o'clock this morning, my colleagues were...'
Learner: '...were preparing their lessons.'
3 Spot the Error
Read these sentences aloud or write them on the board. Ask learners to identify the error in each one and correct it. Discuss as a class.
Example sentences
1. The students was singing when I came in. (✗ → were singing)
2. I was cook dinner when she called. (✗ → was cooking)
3. Were the teacher explaining the rule? (✗ → Was the teacher...)
4. He was knowing all the answers. (✗ → He knew all the answers.)
5. They weren't listen carefully. (✗ → weren't listening)

Plan Your Next Steps

For each strategy, choose the option that best describes where you are now.

Practise producing past continuous sentences about your own day — what were you doing at specific times? This is the most natural way to make the form automatic.
Notice how the past continuous and simple past work together in stories and news reports — look for the pattern of 'background action + sudden event'.
Pay attention to state verbs (know, want, believe, need, like) and remind yourself that these do not normally appear in the continuous form.
Listen to your learners carefully — if they say 'was + base form' (e.g. 'was go'), address this as a priority: the -ing form is always needed.
Use 'When' and 'While' as classroom prompts — these words naturally invite past continuous + simple past combinations and give learners a useful starting point.
What is the one change you will make next time you teach this grammar point?

Key Takeaways

1 The past continuous is formed with was/were + the -ing form of the main verb — both parts are always needed.
2 Use 'was' with singular subjects (I, he, she, it) and 'were' with plural subjects (we, they) and 'you'.
3 The past continuous describes an action that was in progress at a specific moment in the past — it was not yet finished.
4 A very common pattern is: past continuous (background action) + when + simple past (sudden event).
5 State verbs such as know, want, and believe are not normally used in the continuous form — use the simple past instead.
