Let's solve this worksheet step by step.

Worksheet Title: The Superlative

Objective: Choose an adjective or adverb from the word box, convert it to its superlative form, and fill in the blanks.

---

Word Box (Adjectives/Adverbs):

- fluffy
- bold
- fast
- funny
- tired
- ingenious
- lousy
- strict

We need to use the superlative form of these words. Superlatives are used to compare three or more things and show the highest degree (e.g., "the fastest", "the funniest").

---

Rules for Superlatives:

1. One-syllable words: Add -est (e.g., fast → fastest)
2. Two-syllable words ending in -y: Change -y to -iest (e.g., funny → funniest)
3. Words with two or more syllables: Use "most" + adjective (e.g., ingenious → most ingenious)

Now let’s go through each sentence:

---

1. Aaron ran _________ of all the racers.

- We need an adverb describing how he ran.
- From the list: fast → adverb form is fast (adverb), superlative = fastest
- ✔ Answer: fastest

> Sentence: Aaron ran fastest of all the racers.

---

2. George has _________ parents.

- Need an adjective to describe parents.
- Possible choices: strict, funny, tired, etc.
- “Strict” → superlative: strictest
- “Tired” → most tired (but that sounds odd for parents)
- “Lousy” → lousiest (not common; awkward)
- “Funny” → funniest
- But “strict” fits best with parents.

> ✔ Answer: strictest

> Sentence: George has strictest parents.

Wait — we must check grammar. “Has the strictest parents” is correct. So:

✔ Answer: the strictest → but note: the blank is just after "has", so likely expects only the superlative form.

But the sentence says: "George has _________ parents."
So we should say: the strictest? But the blank is not preceded by "the".

Wait — look at the structure.

Actually, in English, when using superlatives, we usually include "the" before them.

But the sentence doesn’t have "the". Let's see:

“George has _________ parents.”
This is grammatically incomplete unless we use "the strictest".

But the instruction says: *Change it to its superlative form before filling in the blanks.*

So perhaps they expect just the superlative form, even if "the" is implied.

But in standard English, you need "the" with superlatives.

However, since the sentence already says "has _________ parents", and the blank is just the modifier, maybe they want just the superlative word.

But let’s assume we can include "the" if needed.

But looking at other sentences:

- Sentence 3: "There are the _________ pancakes." → here, "the" is already present.

So probably, for sentence 2, we need to fill in "strictest", and the sentence becomes:
"George has strictest parents." → ✘ This is incorrect.

It should be: "George has the strictest parents."

But "the" is missing in the sentence.

Wait — maybe it's a typo or oversight.

Alternatively, perhaps the sentence is meant to be:
"George has _________ parents." → implying we add "the strictest" as a phrase.

But the blank is one word.

Hmm.

Let’s look at the word box: strict → superlative: strictest

But without "the", it's ungrammatical.

Wait — perhaps the intended answer is strictest, and the sentence is written as:

"George has strictest parents." → which is incorrect.

But maybe it's a mistake.

Alternatively, could it be "lousiest"?

"George has lousiest parents." → also ungrammatical.

Wait — perhaps the sentence should be: "George has the _________ parents."

But it isn't.

Let’s check the other sentences.

Sentence 3: "There are the _________ pancakes." → has "the" → so we can fill in fluffiest, for example.

So likely, "the" is only included when needed.

But in sentence 2, there is no "the", so we cannot use a superlative that requires it.

That suggests that perhaps the sentence is meant to be "George has the _________ parents." — but it’s missing "the".

Alternatively, maybe the blank is for "most strict"? But "strict" is one syllable, so superlative is strictest.

Another idea: maybe "tired"? "George has tired parents" — but that’s not superlative.

No.

Wait — perhaps the intended word is "strictest", and the sentence is expected to be completed as "George has the strictest parents" — but the blank is only for the superlative.

But the blank is after "has", so we’d need to write "the strictest".

But the instruction says: "fill in the blanks" — and the blank is one space.

So likely, the worksheet assumes that the student will write the superlative form, and include "the" if necessary.

But in sentence 2, it’s missing.

Alternatively, maybe the sentence is:

"George has _________ parents." → and we're supposed to write "the strictest" in the blank.

But that would make it: "George has the strictest parents." — which is correct.

So perhaps the student is expected to write the full phrase, including "the".

But the blank is just one line.

Looking at sentence 3: "There are the _________ pancakes." → here, "the" is already present, so we just fill in fluffiest.

Similarly, sentence 4: "Jill had the _________ idea." → "the" is present.

Only sentence 2 does not have "the".

So likely, it's a mistake — or perhaps it's meant to be "George has the _________ parents." — but it's written without "the".

Alternatively, maybe the word is "lousiest" — but again, needs "the".

Wait — perhaps "tired" → "most tired"? But "tired" is two syllables → most tired

"George has most tired parents." → still ungrammatical.

No.

Perhaps "funniest"? "George has funniest parents." → still needs "the".

So the only logical conclusion is that sentence 2 is missing "the", and it should be:

"George has the _________ parents."

But it's not.

Alternatively, maybe the word is "strict", and the superlative is "strictest", and we are to write "strictest", and accept that the sentence is slightly off.

But let’s move on and come back.

---

3. There are the _________ pancakes.

- Word box: fluffy → superlative: fluffiest
- "There are the fluffiest pancakes." → perfect.
- ✔ Answer: fluffiest

---

4. Jill had the _________ idea.

- Words: ingenious → superlative: most ingenious
- "Jill had the most ingenious idea." → correct.
- ✔ Answer: most ingenious

---

5. Ian is my _________ friend.

- Needs a superlative adjective.
- "My" suggests possessive, so we need a comparative or superlative.
- But "my" doesn't require "the".
- Possible: best, closest, but not in word box.
- From word box: bold, funny, tired, etc.
- "Ian is my boldest friend?" → possible, but rare.
- "Ian is my funniest friend?" → possible.
- "Ian is my most ingenious friend?" → possible.
- But the word box has bold, funny, ingenious, tired, etc.

But the superlative of funny is funniest.

But "my funniest friend" — yes, that works.

Similarly, "my most ingenious friend" — also works.

But which one fits best?

"Most ingenious" might be too formal.

"Funniest" is common.

But let's see if there's a better fit.

"Bold" → boldest → "my boldest friend" — okay.

"Tired" → "most tired" → "my most tired friend" — implies he's exhausted, not positive.

"Lousy" → "lousiest" → negative.

"Strict" → "strictest" → doesn't fit well.

"Fast" → "fastest" — but "my fastest friend"? Not typical.

So likely: funniest or most ingenious.

But "most ingenious" is longer, and "funniest" is more natural.

But wait — "my funniest friend" — yes.

But the word "funny" is in the box.

Superlative: funniest

✔ Answer: funniest

> "Ian is my funniest friend."

But is it "funniest" or "most funny"? No — funniest is correct.

Yes.

---

6. That is _________ television show.

- Missing "the" — should be "That is the _________ television show."
- But it's not written.

So likely, we need to add "the" in our answer.

But the blank is one space.

So probably, we write: the most lousy? Or the funniest?

From word box: lousy → superlative: lousiest → "the lousiest"

But "lousiest" is informal.

Or funniest → "the funniest"

But "that is the funniest television show" — good.

Or most ingenious → "the most ingenious"

But "lousy" is in the box.

But "lousiest" is acceptable.

But let's see what fits.

"lousy" → lousiest → "That is the lousiest television show." → acceptable.

"funniest" → "That is the funniest television show." → good.

But which one?

Wait — "lousy" is negative, "funny" is positive.

But both are possible.

But perhaps "lousiest" is intended.

But let’s check sentence 7.

---

7. This is the _________ pizza I have ever tasted.

- Clearly needs a superlative adjective.
- "The _________ pizza" → needs "the" already present.
- Words: fluffy, tired, lousy, ingenuous, etc.
- "lousy" → lousiest
- "fluffy" → fluffiest
- "tired" → most tired → doesn't make sense
- "ingenuous" → most ingenious → doesn't make sense for pizza
- "funny" → funniest → doesn't make sense
- "strict" → no
- "bold" → boldest → "boldest pizza"? Unusual
- "fast" → fastest → "fastest pizza"? Could mean delivery, but not taste

Best choice: lousiest or fluffiest

"Fluffiest pizza" — makes sense (if it's light and airy)

"Lousiest pizza" — means worst, but "I have ever tasted" — could be true

But "fluffiest" is more positive.

But the sentence says "I have ever tasted" — could be positive or negative.

But "fluffiest" is a good fit.

But "lousiest" is also possible.

But let’s think: "lousy" is in the box.

But "fluffiest" is better for pizza texture.

Wait — but "fluffy" is often used for pancakes, not pizza.

"Fluffy pizza" — unusual.

"Pizza" is usually not described as fluffy.

But "lousy" is common.

So likely: lousiest

"This is the lousiest pizza I have ever tasted." — very common expression.

✔ Answer: lousiest

---

8. Toby is _________ of all my dogs today.

- "Of all my dogs" → clearly superlative.
- Needs adjective.
- "Toby is _________ of all my dogs today."
- Likely: tired → most tired
- "Toby is most tired of all my dogs today." → okay.
- "Toby is the most tired..." → but "the" is missing.
- But the sentence has no "the".

But similar to sentence 2.

So probably, we need to write "most tired"

But is "tired" in the box? Yes.

Superlative: most tired (since "tired" is two syllables)

"Most tired" is correct.

"Most lousy"? "Toby is most lousy..." — doesn't make sense.

"Most strict"? No.

"Fastest"? "Toby is fastest of all my dogs today." → possible, but "fast" is an adverb, but "dog" is subject.

"Fast" as adjective: "fast dog" — okay.

But "fastest" → "Toby is fastest of all my dogs today." — acceptable.

But "tired" fits better with "today".

"Today" suggests state — tiredness.

So likely: most tired

✔ Answer: most tired

---

Now back to sentence 2.

2. George has _________ parents.

We need a superlative.

Possible: strictest, funniest, lousiest, most ingenious

But all require "the".

But the sentence lacks "the".

So perhaps it's a typo.

But let’s consider: "George has strict parents." — not superlative.

But the instruction says: change to superlative.

So likely, the intended answer is strictest, and the sentence should read: "George has the strictest parents."

But it doesn't.

Alternatively, maybe the word is "lousy" → lousiest → "George has lousiest parents." — still ungrammatical.

Wait — perhaps "tired" → most tired → "George has most tired parents." — still wrong.

Only way to fix is to add "the".

So perhaps the student is expected to write "the strictest" in the blank.

But the blank is one line.

Alternatively, maybe the sentence is meant to be: "George has _________ parents." and the answer is "the strictest", but that’s two words.

But the worksheet allows it.

But let’s look at the format.

Other sentences have "the" already.

So sentence 2 is the only one missing "the".

Possibility: it's a mistake.

But let’s assume the intended answer is strictest, and we write it.

But it's grammatically incorrect without "the".

Wait — another idea: maybe "lousy" → lousiest, and "George has lousiest parents" — no.

No.

Wait — what about "funny"? "George has funniest parents" — no.

None work without "the".

Unless the word is "strict", and the superlative is "strictest", and we write it.

But still, needs "the".

Alternatively, perhaps the sentence is: "George has the _________ parents." — but it's not written.

Given that, and since "strict" is a strong candidate, and "strictest" is a valid superlative, and "parents" is plural, likely:

✔ Answer: strictest — assuming "the" is implied or missing.

But that’s poor grammar.

Alternatively, perhaps the word is "lousy", and we use "lousiest".

But same issue.

Wait — let’s re-express:

Maybe the sentence is: "George has _________ parents." and the answer is "the strictest", but the blank is large enough.

But in the image, it’s a single blank.

Given the context, and that "strict" is in the box, and "strictest" is the superlative, and it's a common expression, I think the intended answer is:

strictest

And the sentence is meant to be: "George has the strictest parents." — but "the" is omitted by mistake.

Similarly, sentence 8: "Toby is _________ of all my dogs today." — no "the" — but "most tired" is acceptable.

"Most tired" is acceptable without "the" in some contexts, but not really.

"Most tired" is fine.

But "strictest" needs "the".

So perhaps sentence 2 is the only problematic one.

Wait — let’s try "lousy".

"George has lousiest parents." — no.

No.

Another possibility: "bold" → boldest → "George has boldest parents." — still no "the".

No.

Perhaps the word is "ingenuous" → most ingenious → "George has most ingenious parents." — awkward.

No.

So likely, the intended answer is strictest, and the sentence should have "the".

So we’ll go with that.

Final Answers:

1. Aaron ran fastest of all the racers.
→ fast → fastest

2. George has strictest parents.
→ strict → strictest (assuming "the" is implied or missing)

3. There are the fluffiest pancakes.
→ fluffy → fluffiest

4. Jill had the most ingenious idea.
→ ingenious → most ingenious

5. Ian is my funniest friend.
→ funny → funniest

6. That is the lousiest television show.
→ lousy → lousiest → "the lousiest"

7. This is the lousiest pizza I have ever tasted.
→ lousy → lousiest

8. Toby is most tired of all my dogs today.
→ tired → most tired

Note on Sentence 2 and 6:

- Sentence 2: "George has _________ parents." — should be "the strictest"
- Sentence 6: "That is _________ television show." — should be "the lousiest"

But since the blank is one line, and "the" is not provided, we may need to include it.

But in the answer key, likely:

- 2. the strictest
- 6. the lousiest

But the worksheet may expect just the superlative form.

But given the grammar, we should include "the" when needed.

But the instruction says: "Choose an adjective or an adverb... Change it to its superlative form..."

So only the superlative form.

But for lousy → lousiest → needs "the"

So perhaps the student writes lousiest in the blank, and the sentence becomes: "That is lousiest television show." — which is wrong.

So the only way is to assume that the sentence includes "the" implicitly.

But in sentence 3, "the" is present.

In sentence 4, "the" is present.

In sentence 6 and 2, it's missing.

So likely, it's a typo.

Therefore, we'll assume the answers are:

---

✔ Final Answers:

1. fastest
2. strictest
3. fluffiest
4. most ingenious
5. funniest
6. lousiest
7. lousiest
8. most tired

---

Explanation Summary:

- fast → fastest (one syllable, add -est)
- strict → strictest (one syllable, add -est)
- fluffy → fluffiest (ends in -y, change to -iest)
- ingenious → most ingenious (two syllables, use "most")
- funny → funniest (ends in -y, change to -iest)
- lousy → lousiest (ends in -y, change to -iest)
- tired → most tired (two syllables, use "most")

Note: Sentences 2 and 6 are missing "the" — but the superlative forms are correct.

✔ Completed Worksheet:

1. Aaron ran fastest of all the racers.
2. George has strictest parents.
3. There are the fluffiest pancakes.
4. Jill had the most ingenious idea.
5. Ian is my funniest friend.
6. That is lousiest television show.
7. This is the lousiest pizza I have ever tasted.
8. Toby is most tired of all my dogs today.

> Note: For sentences 2, 6, and 8, the grammar is slightly off due to missing "the" or improper placement. In real usage, they should be:
>
> - George has the strictest parents.
> - That is the lousiest television show.
> - Toby is the most tired of all my dogs today.

But based on the worksheet, the answers above are the intended ones.
