Use “passed” when you need the past form of the verb “pass”. Use “past” for an earlier time, a position beyond something, or movement beyond when no verb “pass” is required.
Compare “She passed the library” with “She walked past the library”. In the first sentence, passed is the main verb. In the second, walked is the verb and past tells where she walked.
Try this now: ask your child to underline the verb in each sentence. If the blank must carry the action “went by”, use passed. If another verb already carries the action and the blank means “beyond”, use past.

1. Choose by grammatical job
Cambridge identifies passed as the past simple and past participle of the verb pass. Cambridge records past in several jobs, including time before the present and a position beyond a point.
| Word | Usual job | Quick meaning | Example |
|---|---|---|---|
| passed | Verb form | went by; succeeded; gave; approved; elapsed | She passed the gate. |
| past | Preposition | beyond a place or time | She walked past the gate. |
| past | Adverb | to or on the farther side | The cyclist sped past. |
| past | Adjective | earlier; previous | Past mistakes can teach us. |
| past | Noun | time before now | We learned from the past. |
Because pass has several meanings, the best test is grammatical as well as semantic. “He passed the test,” “She passed the note” and “Time passed” all use a verb.
2. Use sentence pairs that expose the difference
| Sentence with passed | Sentence with past | What changed |
|---|---|---|
| The bus passed the school. | The bus drove past the school. | Passed is the verb; drove is the verb in the second sentence. |
| An hour passed. | It is past noon. | One describes time elapsing; the other locates time beyond noon. |
| She passed me in the race. | She ran past me in the race. | The second sentence already has ran as its verb. |
| He passed the examination. | The examination is in the past. | Success versus earlier time. |
A reliable substitution check
If went by, succeeded, gave or elapsed can replace the blank as a verb, passed may fit. If beyond, earlier or time before now fits, choose past.
Do not rely only on “another verb is present”. A sentence can contain more than one verb. Instead, identify what job the target word itself performs.
3. Diagnose the most common traps
- “We drove passed the shop.” Drove already carries the action; the intended meaning is beyond, so write past.
- “The runner past the finish line.” The sentence needs a past-tense verb, so write passed.
- “In passed years.” The word describes earlier years, so write past years.
- “The time is passed ten.” For clock position beyond ten, write past ten.
- “She past her test.” Success in a test uses the verb passed.
Ask the learner to explain the correction with both meaning and word class. “It sounds right” is not transferable evidence.
Original mini-check: cover the target word and read the sentence aloud. Name the main action, then decide whether the blank performs that action or merely locates movement or time beyond a point.
4. Transfer the choice into real writing
Fill-in-the-blank practice is useful only as a beginning. The learner should next revise sentences in a paragraph, then write original sentences in which the two words appear naturally.
| Task | Evidence to look for |
|---|---|
| Choose in isolated sentences | Correct meaning and grammatical label |
| Correct an error in a paragraph | Ability to use surrounding syntax |
| Write one sentence with each word | Independent control of structure |
| Explain a peer’s error | Clear reason, not a mnemonic alone |
| Use the words a week later | Retention and transfer |
A happy way to practise is to write a tiny journey: “We passed the bakery, walked past the park and talked about past holidays.” The repetition makes the contrast visible without turning it into a spelling lecture.

5. Match correction to the learner’s stage
A younger learner may benefit from identifying the verb and using “went by” versus “beyond”. An older student should be able to name the relevant word class, edit authentic prose and maintain accuracy under timed writing conditions.
Tuition should diagnose whether the difficulty is spelling memory, sentence grammar or meaning in context. Copying the pair ten times may improve appearance without repairing the underlying decision.
Current pathway note, checked 11 October 2026: Posting Groups 1, 2 and 3 support admission to secondary schools; they are not subject levels. Individual secondary subjects may be taken at G1, G2 or G3 according to the student’s programme and the subject available. See MOE’s Full Subject-Based Banding pathway overview. The Singapore-Cambridge Secondary Education Certificate (SEC) begins in 2027; the applicable syllabus depends on subject, level, examination year and candidate type, and not every subject is available at every level.
The progress check is simple: can the learner choose correctly in a new sentence, underline the grammatical evidence and explain the choice in one calm sentence?
Discuss the learning evidence, calmly
A useful tuition conversation starts with the exact task, the child’s first answer and the reason behind it. For confused-word choices in English, one short contrast often reveals more than a long worksheet.
eduKateSG’s verified 3-pax positioning allows close attention to explanation, correction and transfer. It does not promise a grade. The practical question is whether the learner can use the idea independently on a fresh example.
Ask eduKateSG about a calm parent–student consultation on WhatsApp. Bring one recent school task and one independently attempted correction.
