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.
Before you start — think honestly about your own teaching and experience.
Look at the examples. Answer each question before reading the explanation — this is how your students will learn too.
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.
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.
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.
| Form | Use / Meaning | Example |
|---|---|---|
| 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. |
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'.
Choose the correct form to complete each sentence.
Each sentence contains one error. Write the correct sentence and explain the mistake.
Use this sequence directly in class — guided discovery, no textbook needed. Tap each step to mark it done.
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?'
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.
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.
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.
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.
