Grade 1 Grammar: Adjectives adding -er and -est printable ... - Free Printable

Let’s go through each sentence one by one and pick the right word from the Word Bank to fill in the blank. We’ll think about what makes sense in each sentence.

Word Bank: wet · young · rare · simple · fast · silly · quiet · long

1. The enormous diamond was a _______ diamond in the whole world.

We’re talking about a diamond that is “enormous” — very big and special. That means it’s not common. So we want a word that means “not common.”
→ rare fits best. (A rare diamond = hard to find, very special)

✔ Answer: rare

2. I like my teacher because she is always _______.

What kind of teacher do kids usually like? Someone who doesn’t yell or make noise too much? Or someone who tells jokes? Let’s look at the options.
“Quiet” could work if she’s calm. But “silly” might also fit if she’s fun. Wait — let’s read the next sentences for clues. Actually, no — we should just pick what makes most sense here.
But hold on — maybe “quiet” isn’t the best. Teachers aren’t always liked for being quiet. Maybe “silly”? Hmm. Let’s skip and come back.

Wait — actually, looking again: “I like my teacher because she is always _______.”
If she’s always “silly,” that could be fun. If she’s always “quiet,” that might be boring. But maybe she’s calm and peaceful? Still… let’s check other sentences first.

Actually, let’s try this: In many classrooms, kids like teachers who are fun — so “silly” could work. But let’s see if another word fits better later. For now, let’s tentatively say silly — but we’ll double-check.

Wait — maybe “kind”? Not in the bank. “Nice”? Not there. So among the words given, “silly” or “quiet” are possible. Let’s keep going.

3. My brother is _______; he is ten in the third grade, but he is in the sixth grade.

He’s only 10 years old but already in 6th grade? That means he’s ahead of others — smart or advanced. But none of the words mean “smart.” Wait — maybe “young”? He’s young for his grade level. Yes! He’s only 10, which is younger than most 6th graders. So he’s young for his grade.

✔ Answer: young

4. It is not _______ to get lost in the forest. There is always someone walking around making sure that people don’t get lost.

This says it’s NOT something to get lost — meaning it’s easy to avoid getting lost. So the blank should be a word that means “hard” or “difficult.” But our word bank has “simple” — which means easy. So if it’s NOT simple to get lost → that means it’s hard to get lost → which matches the rest of the sentence (“someone is watching”).

So: “It is not simple to get lost...” → meaning it’s difficult to get lost → yes, that works.

✔ Answer: simple

5. John was _______ than two other runners. He almost won the race!

He almost won → so he was very close to winning → that means he was faster than the others. So we need a comparative form. The word “fast” can become “faster”.

The sentence says “John was _______ than two other runners.” → so we need “faster”.

Is “faster” in the word bank? The bank says “fast” — but remember the lesson at the top: you can add -er to short adjectives. “Fast” becomes “faster”.

So even though the bank says “fast”, we use “faster” in the sentence.

✔ Answer: faster

6. My family went on a road trip last summer. It was the _______ trip that we had ever taken.

They’re comparing this trip to all past trips. They’re saying it was the MOST something. The sentence ends with “ever taken” → superlative.

Which word from the bank can become a superlative? “Long” → longest. “Wet” → wettest. “Silly” → silliest. Etc.

What kind of trip would they remember as “the ___ trip ever”? Probably the longest — because road trips are often measured by distance or time.

Also, “longest” makes sense: “It was the longest trip we had ever taken.”

✔ Answer: longest

Now let’s go back to #2: “I like my teacher because she is always _______.”

We have left: wet, quiet, silly (we used rare, young, simple, fast→faster, long→longest)

Used so far:
1. rare
3. young
4. simple
5. faster
6. longest

Left: wet, quiet, silly

Which one fits best for a teacher? “Wet” doesn’t make sense. Between “quiet” and “silly” — both could work, but let’s think: if a teacher is always silly, kids might like her because she’s fun. If she’s always quiet, maybe she’s calm — but “always quiet” might not be why kids like her.

In many school contexts, “silly” is a positive trait for a teacher — makes class fun.

Also, looking at the illustration on the page — there’s a moose and some cute animals — maybe the tone is playful. So “silly” fits.

✔ Final choice for #2: silly

---

Now let’s list all answers:

1. rare
2. silly
3. young
4. simple
5. faster
6. longest

Double-check spelling and grammar:

- “faster” and “longest” are correctly formed from “fast” and “long” using -er and -est rules taught at the top.
- All words make sense in context.

Final Answer:
1. rare
2. silly
3. young
4. simple
5. faster
6. longest
