Irregular Past Tense Verbs Worksheets - ReadingVine - Free Printable

Let's solve this worksheet step by step. The task is to fill in the correct form of the verb in parentheses for each sentence, based on whether it's a regular or irregular verb and the context (present or past tense).

🔹 Part 1: Regular Verb Conjugation

Regular verbs typically add -s in the present simple for third-person singular subjects (he, she, it), and -ed in the past tense.

But here, all sentences are in the present simple tense, so we use:
- Base form for I, you, we, they
- Add -s for he, she, it

Let’s go through each:

1. I always ________ (walk) to school.
→ "I" is first person singular → base form
✔ walk

2. She ________ (watches) TV every night.
→ "She" is third person singular → already given as "watches"
✔ watches *(Note: This is actually irregular in form but common; however, "watch" is regular, so "watches" is correct)*

3. They ________ (play) soccer on Saturdays.
→ "They" → plural → base form
✔ play

4. He ________ (studies) for his exams.
→ "He" → third person singular → adds -s
✔ studies

5. We ________ (cook) dinner together.
→ "We" → plural → base form
✔ cook

6. You ________ (visit) your grandparents every summer.
→ "You" → base form
✔ visit

7. The cat ________ (chases) the mouse.
→ "The cat" = third person singular → adds -s
✔ chases

8. The flowers ________ (bloom) in the spring.
→ "Flowers" = plural → base form
✔ bloom

9. The birds ________ (sing) beautifully.
→ "Birds" = plural → base form
✔ sing

10. The children ________ (laugh) and play.
→ "Children" = plural → base form
✔ laugh

✔ Regular Verbs Answers:
1. walk
2. watches
3. play
4. studies
5. cook
6. visit
7. chases
8. bloom
9. sing
10. laugh

🔹 Part 2: Irregular Verb Conjugation

These are in the past tense, so we need the past form of irregular verbs. These do not follow the -ed rule.

Let’s go one by one:

1. I ________ (see) a movie last night.
→ Past of "see" = saw
✔ saw

2. She ________ (ate) breakfast before she left.
→ "Ate" is already the past tense of "eat"
✔ ate

3. They ________ (swam) in the lake.
→ "Swam" is the past tense of "swim"
✔ swam

4. He ________ (bought) a new car.
→ "Bought" is the past tense of "buy"
✔ bought

5. We ________ (teach) English to children.
→ Wait — this is present tense? But the rest are past. Let's check:
→ No time marker like "yesterday" or "last week", but the sentence says "we teach English" — likely present tense.
→ However, since this section is titled Irregular Verb Conjugation and others are past, let’s double-check.

But look at the sentence: “We ________ (teach) English to children.”
→ It doesn’t specify past tense. But the other sentences in this section are clearly past (last night, yesterday, etc.).
→ Actually, this one might be an error or out of place.

Wait — let's look at the full list:
- Sentence 1: last night → past
- 2: before she left → past
- 3: swam → past
- 4: bought → past
- 5: teach → no time clue?

Hmm — perhaps it's meant to be present tense, but that breaks the pattern.

But looking closely:
→ The instruction says: *"Fill in the correct form of the verb in parentheses to complete each sentence."*
→ So we must consider context.

Sentence 5: "We ________ (teach) English to children."
→ No past indicator → likely present tense
→ But "teach" is regular, not irregular!
→ Wait — this is confusing.

Let’s review:
- Teach is a regular verb → past is "taught"
- But "teach" itself is not irregular — it’s regular.
→ However, the section is labeled Irregular Verb Conjugation, so maybe it's a mistake?

But wait — "teach" has an irregular form? No.
→ "Taught" is the past tense of "teach" — and it's irregular because it doesn't follow the -ed rule (it's "taught", not "teached").

So yes — "teach" is irregular:
- Base: teach
- Past: taught
- Past participle: taught

So the sentence should be in past tense if it fits the theme.

But again — no time clue.

Let’s compare with others:
- 1: last night → past
- 2: before she left → past
- 3: swam → past
- 4: bought → past
- 5: ??? → no time word → ambiguous

But the verb is "teach" → if it's past, then taught
If present, teach

But the context of the section is past tense irregular verbs, so likely intended as past.

So:
✔ taught

(Even though the sentence lacks a time marker, it fits the pattern.)

6. You ________ (run) five miles yesterday.
→ "Yesterday" → past tense
→ Past of "run" = ran
✔ ran

7. The dog ________ (bit) the mailman.
→ "Bit" is the past tense of "bite"
✔ bit

8. The leaves ________ (fell) from the trees.
→ "Fell" is the past tense of "fall"
✔ fell

9. The fish ________ (swam) away.
→ "Swam" is past of "swim"
✔ swam

10. The people ________ (saw) the fireworks.
→ "Saw" is past of "see"
✔ saw

Now back to #5:
→ "We ________ (teach) English to children."

Given that all others are past tense, and "teach" is irregular (past = taught), it's most logical that this is also past tense.

So even though no time word is used, it fits the pattern.

✔ taught

📝 Explanation Summary:

- Regular verbs follow predictable patterns:
- Present: add -s for third person singular (he, she, it)
- Past: add -ed (e.g., walk → walked)

- Irregular verbs have unique past forms that don’t follow rules:
- Examples: see → saw, eat → ate, swim → swam, buy → bought, run → ran, fall → fell, bite → bit, teach → taught

This worksheet helps students distinguish between regular and irregular verbs and practice their correct conjugations in context.
